Strybing Arboretum
The Oudtshoorn pincushion, Leucospermum erubescens, is just one many exotics from South Africa to be found at the Strybing Arboretum and Botanical Garden.

Strybing Arboretum and Botanical Gardens

Three out of the four days I was in San Francisco last week I managed to visit the Strybing Arboretum in Golden Gate Park. The first day I got there about 3PM, after my visit to the Conservatory of Flowers and window-shopping in the Haight. I’ve visited the Strybing several times before and was tired out from walking around, so I went to rest in one of my favorite spots, the coastal redwood glen. I lay there for a very long time, looking up at the redwoods, the illusion of being deep in the wood disturbed only by traffic sounds (well, that and the fact that I was lying on a park bench).

Shortly after 5, I felt rested and ready to takes some photos. First I had to find the facilities. When I did, they were locked. I dashed to the other side of the gardens. Those were locked, too. Turns out that the Strybing closes at 4:30. If I left now to find a restroom, I wouldn’t be able to get back inside. I was disappointed but I had no choice.

I decided that I was going to feel cheated if I didn’t go back to take some photos. I’ve done my sight-seeing on previous trips and shopping does not entice me. So the next morning I got to the Strybing first thing after breakfast. It was a rare sunny morning. Morning is definitely the best time to visit (if it’s a sunny day) because the garden is better lit than even mid-afternoon when the tall trees put all the understory plants in shade.

The only problem is that the rainbirds are going. So you have to be careful to dodge them or risk getting drenched.

Given how very dry the climate is, I was surprised that the Strybing used rainbirds instead of drip irrigation to water. San Francisco is a gardeners’ paradise. The temperatures are cool but there is plenty of sun. The only problem is water.

The Strybing is huge, 55 acres, and it seems larger because the beds are laid out in a very, naturalistic way with small paths that seem to wind every which way and lead you in circles. Even with a map in hand, I always get turned around. Collections are grouped by place of origin so that the climatic conditions can be mimicked. Rather than create geometric garden rooms, hills, berms, and trees isolate each area and obscure most views.

There are only a couple of open places in the garden. On entering the Strying the first thing you see is the Great Meadow, which is just a lawn with a small fountain at the far end. This is the least interesting space to a gardener. It is the people place, where people to go and lie on the grass and read or watch their kids run free among but away from the valuable plants and trees. The paths lead you to the right, to the other open space of the Wildfowl pond.

Perversely (given the design of the garden) my favorite view is a long unbroken one looking either toward (or from) the Zellerback Garden of Perennials. I like to sit under the arbor (which was drenched with white wisteria, this trip) and write. When I consult the map, I discover that the entire garden is built on an axis that goes from the entry to the arbor in the Garden of Perennials. One would never guess that being in the garden.

As natural as it seems, the Strybing Arboretum (and the entire Golden Gate Park) is a made place, built on wind-swept sand dunes. The designer, John McLaren, spent 56 years acquiring plants from all over the world and arranging them in natural-looking landscapes. According to a sign in the park, “When he reached the mandatory retirement age of 70 in 1916, pressure from voters resulted in a city statute giving him life-tenure. He died on the job at the age of 96.”

The Strybing is a plant collector’s dream. Want to know what you might stumble across? The pdf listing the 7,000 species currently at the Strybing is 115 pages long! Here’s just a few that caught my eye.

Aeonium tabuliformeWhen I walked into the Strybing, the first thing I saw was this dinner plate aeonium and thought, my goodness, it’s like all the plants are on steroids. Related to sempervivum, the common name suggests that dinner plate aeonium just grows big. But I don’t know…all the plants I saw in San Francisco seemed huge.

The Australian bottlebrush is apparently well-adapted to San Francisco. I saw huge tree-sized specimens blooming everywhere, even some interesting weeping forms. However, I’m a little tired of red flowers in my own garden because I have so many of them and they all clash with each other. So imagine my delight when I saw this lemon bottlebrush, Callistemon pallidus. The pale yellow inflorescences seemed to glow in the twilight. Several cultivars have been introduced in Australia. One is called, appropriately, ‘Austraflora Candle Glow’. I hope they will become available in Texas soon.

Gingko biloba
I grow a gingko, too, but mine is only about six feet tall with a trunk so thin I can wrap my thumb and finger around it. I was astonished to see that someday it might become a very large tree.

Psoralea pinnate
The flowers of Psoralea pinnata, blue broom, had almost the same color and grape soda scent as Texas mountain laurel. But instead of dark round glossy leaves, it had soft, needle-like leaves (which is probably why one of its common names is Dally pine). A native in South Africa it has been introduced to Australia and New Zealand where it is considered an invasive weed.

I’m amazed that two plants on either side of the world, could have flowers so similiar in shape, color and scent, and yet completely different leaves. Don’t things like that just make you want to be a taxonomist, to study the similarities and difference among plants and figure out a way to classify and group them? When I visit a place like the Strybing, it kills any desire to grow only native plants. I want to embrace a world of plants. Life on earth is more fascinating than our wildest imaginings.
