Surprising Beauty: Carnivorous Plants in the Garden

Thursday, July 22nd, 2010

This piece was originally published in August of 2009, but beautiful plants are always worth revisiting, especially in high summer. Enjoy.

Have you noticed how the concept of beauty evolves as you grow older or as you garden longer? Just ten years ago, if you had told me that I would consider a bouquet of carnivorous plants as lovely a sight as I had ever seen, I would have replied (politely, I hope) that I was really more of a pansy, peony or poppy girl. So no-one was more surprised than I was when I recently encountered a bouquet of carnivorous plant spent flower heads and traps and I thought to myself that they were some of the most strikingly lovely plants I’d ever seen. It’s not that I have forsaken peonies, not at all. Rather, I can happily attest that one of the benefits of growing older as a gardener (and as a person) is that your concept of beauty deepens and widens to include all manner of beauty. Photo: A sample of David and Cathy Walther’s carnivorous plant collection, including the double-flowered, speckled white trapped Sarracenia leucophylla ‘Tarnok’.

David Walther, co-owner with his wife Cathy of Spring Fever Nursery in Yankee Hill, has been intrigued by carnivorous plants and been growing them in his home garden for close to 10 years. His collection currently includes many plants comprising multiple varieties of half a dozen or so species. I first saw David’s collection in mid-spring, when a handful were beginning to bloom. I visited them again in late-summer and their dramatic colors, structures and over-all interest were still going strong. While many carnivorous plants have very attractive and showy flowers, it is the traps and the spent seed heads that persist and that, in my opinion, hold multi-season interest for the gardener. Photo: Sarracenia flava, the tall plant with dangling yellow flower petals, in bloom and Sarracenia leucophylla x. willisii ‘Dana’s Delight’ in bud.

Evidence of carnivorous plants dates back to the Cretaceous Period (1144 to 65 million years ago). Currently, botanists believe that there are close to 600 species of carnivorous plants and fungi, from something like 15 genera and 7 families, and which live around the world. Several carnivorous plants are native to California including the California pitcher plant (Darlingtonia californica) and a sundew (Drosera). Photo: A small venus fly-trap (Dionaea muscipula)

Carnivorous plants could also be referred to as insectivorous plants, as insects of all kinds are their normal prey. Carnivorous plants the world over have evolved at different times in response to impoverished circumstances – be it very dry soil without sufficient nutrients or very wet and acidic bog conditions. As result of poor growing conditions, the plants could not derive the nutrients they needed in order to survive and reproduce and so they developed means of getting their nutrients from nutrient-rich insects in the vicinity. The technical definition of a carnivorous plant is one that attracts, captures, kills and digests its prey, but many plant people include as carnivorous plants that just do some of these steps. Photo: David cut open a Sarracenia trap for me to demonstrate how many bugs the plant has digested. While they do capture a lot of bugs, they are not actually effective bug control.

In general, carnivorous plants attract different insects for food than they do for the purposes of pollination. Furthermore, carnivorous plants do not use their reproductive parts (flowers) in order to capture or digest insects and their digestive parts are not involved in pollination or reproduction. Photo: An ant crawling on the operculum or lid of a pitcher trap. The shape of the operculum helps to protect the trap from overflowing with rainwater and helps to direct bugs into the trap.


Beyond botanical classifications, carnivorous plants are categorized by their degree of carnivory – full-time, meaning they do not obtain any of their nutrients from the soil, or part-time, meaning they get some of their nutrients from their soil/water and some from insect prey. They are also categorized by the kinds of traps that they use – active or passive fly-paper (wherein bugs are attracted to a sticky liquid on the plant’s leaves that binds them like glue), pitcher/pitfall and lobster-pot traps (wherein insects are attracted by a scent inside of cup or pitcher which they cannot get back out of) and steel or snap-traps (wherein the traps actually close around the trapped prey, such as the venus fly traps), and finally mousetraps, which are only found on aquatic carnivorous plants and are in the form of a bladder which when triggered inflates itself and sucks in water and its prey. Wow. Amazing, but less lovely in a bouquet, I would think. Photo: David points out the structure of a Sarracenia flower. The petals are the yellow parts hanging down the longest, the sepals are less long and hang down over the petals. David is lifting one up. The stigmas (pointing up and tucked under the petals) are all joined together by an upside-down umbrella-shaped style to form a little basin beneath the pollen-bearing anthers and filaments.

While some plants have been recognized as carnivorous for a very long time, other plants have only recently been recognized as such, including some species of Bromeliads. You might have noticed that bromeliad leaves often form a little cup, which prior to the 1980s was believed to be only for conservation of water. In the 1980s it was discovered that some bromeliads actually absorb and use the nutrients of the insects that (inadvertently or by design) drown in these little water basins. Some other plants’ flowers – like the famed dutchman’s pipes (various Aristolchia) or jack-in-the-pulpits (various Arisaema), look a lot like carnivorous traps, but they are in fact flowers trying to attract pollinators, not traps trying to attract food. Photos: Carnivorous looking non-carnivores. A Dutchman’s Pipe on the left and an Arisaema on the right.

David Walther’s carnivorous plant collection has developed a little each year since he originally became interested in them. Since many carnivores grow naturally in peaty or boggy conditions, David grows his planted in old wine-barrel halfs, which he fills with 50% sand and 50% peat or sphagnum moss. These he keeps watered well. “It’s not that they drink a lot of water, but more that they like wet feet and the materials in which they are planted retain a lot of water, so I don’t actually water these more than I water my other plants,” explains David. Because they generally grow in humid as well as moist conditions, and thrive under stress, David also plants his containers quite tightly, and then overseeds them with a small delicate grass or restio. This grassy cover helps to keep water from evaporating too quickly and keep the plants’ roots cool. While the conditions should be wet, they should not be stagnant. David has mesh-covered drainage holes in his barrels and he prefers his wooden containers over plastic ones because they allow for respiration and evaporation. Photo: David inspecting his carnivorous plants.

Most carnivorous plants are delicate when it comes to replicating their desired conditions. David’s carnivorous plants generally like good amounts of bright light. They do not like being fertilized and he makes sure to water them with rested water – meaning water that you have let sit out in a watering can or a bucket for 12 – 24 hours. This helps to ensure that any added chemicals like chlorine have dissipated. Photo: Two of David’s carnivorous plant containers. David does not cover or take his plants in in winter and they do fine each spring at his 2300 foot elevation location.

Because carnivorous plants allocate their energy perhaps even more carefully than other flowering plants, their structures are fascinating. Unlike other flowering plants that grow leaves primarily for photosynthesis and flowers primarily to attract pollinators so that they can reproduce and ensure the survival of their species, carnivorous plants have to do at least twice that and get it done with less: they grow their traps as well as their flowers, produce their sticky liquids and muscillage to attract insects as well as the enzymes to kill and break the bugs’ down into nutrients. In the winter, when light is low, temperatures are low and bugs are scarce, many carnivorous plants send up leaves called phyllodes not related to the plant’s traps but just for the purpose of additional photosynthesis. Photo: The speckled pattern on Sarracenia traps.

“It is amazing how the many parts all work together – beautifully – towards the ultimate goal of capturing food,” David says to me with evident respect for his plants. He goes on to explain: “Most of the pitfall or lobster-trap style plants have a sort of top – called an operculum - which helps to keep the trap from overflowing with too much rainwater. Most operculum are shaped in such a way that they also help to direct and funnel potential prey in the direction of the trap.” Photos: Left, photo courtesy of David and Cathy Walther: A little frog peeking out of a trap - waiting for a snack. Right: A spider dealing with a bee beneath a spent Sarracenia flower head.

While most bugs should use caution in the presence of a carnivorous plants, some creatures have developed an understanding of how to work with them and take advantage of other insects being attracted to them. While examining some traps, David and I see a green spider that has set up its web on the lip of a Sarracenia’s spent flower head. It is very busy wrapping a bee for later. “Small frogs will creep into a trap backwards and wait for their dinner to come to them,” David tells me. “The business of evolution and survival is ingenious.”

And oddly enough, it is strikingly beautiful at the same time.

How Sweet (and Savory) it is: In the Herb Garden with Nancy Schleiger

Wednesday, July 14th, 2010

Rich, minty, sagey and earthy pine fragrances waft around you as you walk through Nancy and David Schleiger’s 2 acre plus, close to 26 year old garden. Beneath the sheltering canopies of stately old oaks and black walnuts, native plants and aromatic, blooming herbs line the walkways and borders in room after garden room of the long narrow property. The front garden, which greets visitors and acts as a bridge between the quiet street and the Schleiger’s house, is just the beginning. Cross the threshold of the back garden gate and you find yourself craning to see beyond the next gate, around the next corner, over the next border. “How far does the garden go?” you might ask in anticipation, “Oh, a ways,” Nancy might reply, modestly. Nancy Schleiger likes her garden plants to smell good, to taste good, to feel good and to help you to feel good. And whether its the herbs she has been cultivating and selling in our region for so long, or the many, many natives she now cultivates as well - both for her home garden and for her Native Springs Nursery- her plants generally fill all her requirements. Photo: Ornamental oregano.

Nancy, and her husband David, an architect, started working on their Durham garden in the early 1980s, and Nancy first started going to local farmer’s markets shortly thereafter. “I first became interested in herbs as I got to know more growers - especially those from different cultures such as some of the Hmong gardeners - I began to learn how other people use different plants - for food, for medicine. I started to experiment with different herbs and growing new ones each season and soon people started to seek me out for interesting herb selections,” Nancy explained to me as we wandered from the back deck garden, through a native and perennial border room and through a gate into the official Herb Garden. Photo: Nancy Schleiger standing beneath an old oak which reigns over her front garden, much of which is planted with native shrubs and perennials as well as hardy and drought tolerant herbs. (more…)

Heat Loving Succulents

Thursday, July 8th, 2010

With summer’s heat upon us, I am once again amazed at the resilience and beauty of succulents in our North State gardens. I was inspired to revisit this piece on Claude Geffray’s Gardens in Chico.

Look up the word “succulent” in the dictionary and as an adjective you will find something like: juicy, thick and fleshy; from the Latin succus, meaning “juice.” The designation “succulent” describes any plant that “stores water against times of drought in specialized tissues,” according to the Brooklyn Botanic Gardens’ Crazy About Cacti and Succulents. Succulents such as jade (Crassula ovata) or Aloes, store extra water in their leaves, others, including most cacti, store water in their stems, and still others store water in their roots or bulbs. While all cacti are succulents, not all succulents are cacti, but almost all succulents are low-maintenance, drought tolerant, relatively pest and disease free and darn good looking - in or out of bloom, year-round. Photo: A view down a covered shade area to one of Claude Geffray’s demonstration succulent and cacti gardens in Chico.

Claude Geffray, a Frenchman by birth, now longtime resident of the North State is founder/owner of Creative Cacti and Succulents, a landscape design business specializing in inspiring succulent and cacti designs, and Geffray’s Gardens, a specialty grower of a head-spinning array of succulents and cacti and based in Chico. Photo: The sculptural leaves of an Agave attenuata .

I have been aware of succulent plants and their specific beauty since I was a girl growing up at 8,000 feet in Colorado and my best friend’s mother – Janet Findling, a woman of the American West born and raised – had a large collection of potted cacti and succulents. My mother was a world-class professional gardener, but she had a decidedly East coast aesthetic and succulents were not for her – Yuccas were yucky and pokey and hostile, in her mind. But my best friend’s mother adored them. She saw in them the sculptural beauty and built-in strength that draws gardeners to them today – from the very small, candy-colored Sedums to the immense and architectural Yuccas and Agaves. To Mrs. Findling – and thousands of gardeners like her today, succulents and cacti were iconic plants of the American West. Thanks to many good books and many good growers, the array of succulents (from around the world) that are available at nurseries and which we can grow in our gardens today is breathtaking. Succulents from Africa, Australia and South America as well many, many good North American natives are now easily available in the trade. Photo: A typical ruffled Echeveria, which needs some protection from winter frosts - simply placing them in pots beneath the eaves of your house or garage should do the trick.

Claude Geffray’s interest in succulents began in his early twenties when, as an art student in San Francisco, he bought a succulent plant at a flea market. Coming from France, Claude had not seen many plants like this before and its shape and texture caught his artist’s eye. As a group, succulents and cacti have held his fascination ever since. Wanting to settle down from the pace of the city, Claude moved to Chico in 1985. By 1988 he had started his small specialty nursery, Geffray’s Gardens, which is now a premier retail and wholesale provider of cacti and succulents for “interiorscapes, landscapes, and specialized xeriscapes gardens for the Northern California region.” Photo:French-born Claude Geffray at one of his Open Garden days this past summer.

I have heard Claude speak to groups of gardeners about growing, caring for and arranging succulents and cacti - his soft french accent roundly describing the plants of which he is so fond. I have visited his nursery and gardens on open days and each time I have come away with treasures more numerous than I care to admit. The wonderful thing is, the plants I bring home from Geffray’s Gardens don’t die. Which, if you happened to have been seduced by the loveliness and drama of wonderful cacti and succulents from - perhaps - slightly more glamorous environs and vendors in the Bay area or in Southern California, you will know that plants from these locales often don’t take well to the North State - it’s too hot, it’s too cold, it’s too dry, it’s too shady, it’s too windy. It’s not the Bay area or Southern California. When you visit Claude’s displays, it will be clear to you if you live in the Valley or foothill portions of our region that if he has it covered, you should probably have it covered, if it is growing outside for all the heat and cold to bear down on in his garden, then you are pretty safe to plant it outside as well. Photo: A selection of the many colors and shapes of succulent treasures in just one of Claude Geffray’s hoop houses at Geffray’s Gardens in Chico.

Succulents and cacti are available for almost all elevations and gardening zones. Hens-and-chicks (Sempervivums) happily flourished, put off pups (as it is called when a rosette-forming succulent plant has a little baby-version of itself appear and grow along its side), and even bloomed at close to 6,000 feet with plenty of winter snow in my last garden, and there are a handful of Agaves and many Opuntias, Yuccas and Hesperaloes that will thrive in the high country as well. But watch for the gardening zone marked on your plant and if you garden in zone 4 and you’re smitten with a zone 8 succulent - put it in a pot and move it into a protected position or indoors for the winter. For some good succulent how-to books, see this week’s Book Recommendations below. Photo: A pathway through one of the succulent and cacti demonstration plantings at Geffray’s Gardens.

Many things endear succulents to a gardener, not the least of which is that they are almost foolproof - perhaps the greatest cause for failure is OVER WATERING or not providing them with enough drainage, which amounts to the same thing. In general, most cacti and succulents - once established - only want water when they have dried out, once a week, or maybe twice in summer sun. They dislike too much water pooling around their crowns and so, especially in areas of heavy winter rain or wet snows, a mulch of fast draining gravel or sand will be appreciated. Originating from areas where water conservation is necessary for survival, succulents tend to like lean soil, very little if any supplemental food (if you have your plants in containers, Claude recommends half concentration fertilizer every other month during the bloom season), they are not susceptible to most pests or diseases, and they are easy to propagate - they practically root themselves from almost any cutting (or inadvertently broken-off-segment). Try it. Cut off of piece of your succulent, let it sit for a day or so allowing the cut to “heal” over, then stick it in the ground. Water it in a few days. Voila! New succulent. Literally. Photo: Left: Agave victoriae-reginae, Right: Echeveria imbricata in bloom.

An important thing to ask as you search for the perfect succulent or cacti for your garden is this: Where did this plant come from? Sadly, many cacti and succulent are collected illegally from the wild, which does not improve our gardens but rather diminishes the beauty and integrity of our wild lands. Make sure that the plants you are choosing have been grown responsibly and legally. Photo: Cascading Echeveria in a pot on a covered patio.

Claude sells his plants, his specially formulated cacti and succulent planting mix and his bold and interesting container designs year-round at Chico’s Saturday Market. He also holds Open Days at the nursery a few times a year. Not only do you get to peruse the wonderful hoop houses full of succulent treasure, but you also get to walk Claude’s succulent and cacti display gardens - well worth a wander. They give you a good idea of the outdoor drama that these plants provide as well as which ones are hardy. Photo: A row of potted Flapjacks (Kalanchoe thrysiflora) in a Chico garden.

More Info: Geffray’s Gardens also has Black Bamboos, Sago Palms, Hardy Palms, and miscellaneous plants on sale. Hardy Cacti and Succulents can be bought bare root from the growing beds, or in different size containers. They also offer an assortment of clay and ceramic pots as well as our own cactus mix. Geffray’s Gardens is located on Carper’s Court, in Chico. From Esplanade take East Avenue toward Hwy 32. Turn right on Alamo, cross Henshaw, go another 150 yards, and find Carper’s on your right. There will be signs in the adjacent streets. Photo: A tray of small succulent plugs at Geffray’s Gardens.

For further information and dates for upcoming open garden days, please call Claude at 530 345 2849.

Here are a few good books on selecting and growing cacti and succulents. All of my reading recommendations are available in stock (or by special order for the more expensive ones) at Lyon Books in Chico. You can order on-line and Lyon Books is happy to ship. You can also try our wonderful public libraries for these books: Photo: A display garden at Geffray’s Gardens.

A few years ago I read Debra Lee Baldwin’s book entitled Designing with Succulents, and became completely inspired. The book took my schoolgirl-crush on succulents and showed me that it could survive the step-up to a long-term adult relationship. Designing with Succulents convinced me that succulents are not only wonderful as showcase elements in ones or twos, but that you can in fact landscape an entire garden with lush, colorful succulents as the very backbone of your design. The trouble was that a lot of the plants featured in the book were not hardy for me. Photo: Calandrinia grandiflora in a Bay area garden. This wonderfully flowering plant is hardy in the north valley, but will need some protection from very hard frosts.

Then alpine plant expert Gwen Kelaidis, based in Denver, published Hardy Succulents, Tough Plants for Every Climate (Storey Publishing, 2007). It covers a wide range of cacti and succulents good for colder or more extreme climates and gives good advice on how to make the most of microclimates. My favorite photos in the book are those with snow capped cacti. Photo: Mature Agaves punctuate and frame a classical threshold between one garden space and another at the famous Lotusland gardens in Santa Barbara.

Debra Lee Baldwin has recently published Succulent Container Gardens (2009, Timber Press), which is also excellent.

Another good book is The Garden Succulents Primer (Gideon Smith, Ben-Erik van Wyk; Timber Press, 2008), an extensive listing of succulent plant genera and families, with identification and cultivation information.

Many good succulents and cacti are native to our region, are available from accredited growers and are worth trying in your garden. To learn more about these, try looking through: Cacti, Agaves and Yuccas of California and Nevada (Cachuma Press, 2008). Photo: Northern California native canyon Dudleya (Dudleya cymosa).

For the academic and devout, the truly awe-inspiring tome to own would be The Cactus Family (Edward Anderson; Timber Press, 2001). Almost everything you would ever want to know about Cacti is here. And, as a bonus, you could use it as a booster seat for the smallest of your family.

And finally, The Garden Conservancy has a wonderful workshop - Making Room for Succulents in Your Garden - coming up on July 16th:

Heavenly and Hardy Hellebores - with David Walther of Spring Fever Nursery

Thursday, February 18th, 2010

“I like to think they are shy,” David Walther, co-owner with his wife Cathy, of Spring Fever Nursery in Yankee Hill tells me, speaking of his beloved hellebores. “Many varieties of hellebores have flowers that face downward because as winter bloomers they are trying to protect their pollen from wind and rain and snow until pollination takes place. But the difference between the back of a hellebore’s so-called bloom, and its wide - often surprisingly beautiful - face can be a night and day difference.” Photo: A bowl of floating hellebore blooms plucked from the array at Spring Fever Nursery - included are Helleborus orientalis, Helleborus niger and many Hellborus x hyrbidus in single, semi-double and fully double forms.

The Queen of Winter Flowers: Camellias in the Garden with Jerry Mendon

Friday, December 18th, 2009

Camellias - also known as the Queen of Winter Flowers because almost all varieties of the genus bloom from late fall through late spring - are for many gardeners synonymous with history, beauty and refinement. These flowering evergreen shrubs or small trees, idealized in Chinese and Japanese art and literature for centuries, are indigenous in much of Asia. Camellias have been treasured in Europe since first being introduced there in the mid- 1700s, and specimens were first brought to the United States in the very late 1800s. Thriving in the American Southeast and along the American West Coast, the camellia genus is comprised of many species - including Camellia sinensis, from which black and green tea is made from the young leaves - and thousands of named varieties, cultivars and hybrids. Interest in camellias reached fervent levels early in the 20th century when Western plant hunters scoured the globe for new plants to record, collect, propagate and eventually hybridize. It was at this time that individuals and botanical organizations began collections of the prized plants. Photo: As winter bloomers, camellias provide valuable nectar and food for pollinators during the colder months. (more…)

Surprising Beauty: Carnivorous Plants in the Garden

Wednesday, August 12th, 2009

Have you noticed how the concept of beauty evolves as you grow older or as you garden longer? Just ten years ago, if you had told me that I would consider a bouquet of carnivorous plants as lovely a sight as I had ever seen, I would have replied (politely, I hope) that I was really more of a pansy, peony or poppy girl. So no-one was more surprised than I was when I recently encountered a bouquet of carnivorous plant spent flower heads and traps and I thought to myself that they were some of the most strikingly lovely plants I’d ever seen. It’s not that I have forsaken peonies, not at all. Rather, I can happily attest that one of the benefits of growing older as a gardener (and as a person) is that your concept of beauty deepens and widens to include all manner of beauty. Photo: A sample of David and Cathy Walther’s carnivorous plant collection, including the double-flowered, speckled white trapped Sarracenia leucophylla ‘Tarnok’.

David Walther, co-owner with his wife Cathy of Spring Fever Nursery in Yankee Hill, has been intrigued by carnivorous plants and been growing them in his home garden for close to 10 years. His collection currently includes many plants comprising multiple varieties of half a dozen or so species. I first saw David’s collection in mid-spring, when a handful were beginning to bloom. I visited them again in late-summer and their dramatic colors, structures and over-all interest were still going strong. While many carnivorous plants have very attractive and showy flowers, it is the traps and the spent seed heads that persist and that, in my opinion, hold multi-season interest for the gardener.

For the Love of Lavender: Tuscan Heights Lavender Gardens in Whitmore

Friday, June 19th, 2009

Lynette Gooch loves lavender. All kinds of lavender for all kinds of reasons. In the United Kingdom the gardening world has things known as National Collections, wherein when a specific garden has more species or varieties of any one kind of plant than any other garden, they can become designated a National Collection. Private gardens and gardeners are as likely to hold National Collections as larger public botanic gardens. In the United States, we do not have such a scheme, but if we did, Lynette Gooch and her husband Richard might well hold the National Collection of lavender with their 207 different named varieties of lavender at the display gardens in Whitmore: Tuscan Heights Lavender Gardens.

Grown as a culinary and medicinal herb throughout the world, throughout time, lavender (Lavandula) is a genus comprising multiple species and hybrids. Species of the genus originate from the Mediterranean, Africa and Asia, and the genus thrives in the Mediterranean climate of the North State.


The Tuscan Heights’ story started in 1999 when Lynette and Richard, farmer/gardeners at heart, were looking around the North State with possible re-location in mind. Living in Roseville at the time, Lynette is from Calaveras County originally and of strong Italian descent, with fond memories of the large family production garden she grew up helping to tend with her father. “Of five kids, I seem to have been the most gardening inclined, which I think has helped me out here!” she tells me the warm summer day I toured around the gardens. “We were about to leave and head home when Richard by chance picked a local discount classified paper and happened to read about land in Whitmore. ‘Where’s Whitmore?’, he asked me. So we drove up, I got out of the car, looked around, breathed deeply, kicked at the dirt with my foot and said - This is it. Let’s write the check.” Although the sloping land was covered in poison oak, manzanita and blackberry, Lynette knew she was home. The Fern Fire had devastated the area 12 years earlier, and Lynette could see that the soil had begun to recover and was ready for any garden she might want to grow. Neither she, the land nor Richard knew just what that garden would become.

Late Case of Spring Fever? The remedy.

Friday, May 15th, 2009

So, you still have a little spring fever? Have a hankering for something special - out of the ordinary? Maybe you saw a cool plant you were unfamiliar with at a garden on one of our regional garden tours, or in a magazine. Sometimes, one of our outstanding local independent nurseries will do the trick and assuage your hankering: a stolen moment, between hectic errands, spent wandering around a quiet nursery looking at plant tags will often lead to new discoveries.

Beyond garden tours, spring is also the time of year when independent growers with specialty collections will bring their treasures to regional farmers markets, or better yet, will hang a little sign outside their yard that reads: Open Garden and Nursery Stock Sale This Weekend – Rain or Shine. Some people’s hearts race at the thought of a tag sale and the treasures it could hold, mine races at the thought of a grower’s garden open day and plant sale.

I first made the acquaintance of David Walther while I looked over his specialty perennials at the Saturday Chico Farmer’s Market. It was a chocolate-color-splotched geranium leaf that caught my eye – I do love a true geranium – and when the plantsman told me its name was Black Widow geranium, well, you know how it went from there. I had to have it. I gave him the last of the $ in my pocket and juggled the pot between my canvas bags of lettuce, eggs and fresh artichokes. “I am having open days at my nursery garden the next three weekends,” he said, sort of off-hand, as I left.
He didn’t have to tell me twice. Photo: David Walther outside of one of his nursery hoop-houses.
