Ok – and be honest now – how many plants have you killed? As a gardener, the most reassuring (and funny, because true) advice, I have ever heard was from Panayoti Kelaidis, Senior Curator and Director of Outreach at the Denver Botanic Gardens, when he said something along the lines of “If you have killed 100 plants, you are a beginner gardener, if you have killed 1000 plants, you are an amateur, and if you can no longer keep track of how many plants over 1000 you have killed, you are an advanced gardener.” Hallelujah, I’m advanced.

But in all truth, I would rather not kill plants, even in the name of experimentation and learning through trying. When I first began gardening in the northern Central Valley – I had a high mortality rate in my garden: some things died because I planted them too late in Spring and the heat got them, some things died because I planted them too late and the frost got them, some things that said “full-sun” did not really want full CENTRAL VALLEY sun, others things got too much water in winter and rotted, others too little water in summer and died of thirst. HOLY COW! Why even garden here, you might ask. Well, as you know, we garden here because it is in our genes to garden no matter where we are and because if we are pointed in the right direction we do actually learn quickly how to manage with our specific region and climate.

Do you know what an herbarium is?

We have at least two here in the North State. Did you know that?

I did not know either of these things – at least not precisely or with complete confidence, and nor did most of my gardening friends when asked this question.

An herbarium is to plants, what a library is to books. If you love plants (and if you’re reading this essay, you’ve already raised your hand) AND you love the idea of preserving and expanding knowledge about them – then you will love the idea of an herbarium. An herbarium is a catalogue, a collection, a record, a repository and a protectorate of plant life and knowledge about plant life.

Diane Stout loves Prickly Pear (Opuntia spp.) cactus - all kinds of them. She likes them in artwork, she likes them in pots, she likes them in all shapes and sizes all around her Orland garden. She likes them so much she named her nursery in Orland after the plants. The home garden that she shares with her husband Dave is home to nearly 40 individual Opuntia plants, comprising 16 different species or varieties. Opuntias are quite hardy, very low-maintenance and, extremely drought tolerant. In general, they prefer full sun, lean rocky soil with sharp drainage, and once established, they need almost no supplemental water.Photo: Diane began her colllection in earnest by asking for cuttings from mature stands of Opuntias in the area, for instance from old farmsteads or churches. Here an established stand of Prickly Pears complement the side of an old industrial metal quonset hut in Los Molinos.

Opuntia is a genus of close to 200 species of cacti originating to North, Central and South America and the West Indies. The genus can be divided into what some people call the Prickly Pear cacti – with round but flatter pads, and the Cholla or Teddy Bear cacti – with heavily spined, oblong sausage-shaped pads. California beavertail cactus (Opuntia basilaris), Teddy Bear Cholla (O. bigelovii), Pancake or Dollar Joint Prickly Pear (O. chlorotica), Silver or Golden Cholla (O. echinocarpa), Old Man Prickly Pear (O. erinacea), and Buckhorn Cholla (O. acanthocarpa), are all considered native to California – mostly to the desert scrub and desert woodland regions of the state.
