I went to Alcatraz last week for the first time since a field trip in grade school. Wow, I should of gone sooner. It’s a fascinating spot and more than just a place to take out-of-town visitors.

The prison is of course iconic and there are great views of the Golden Gate and the rest of the bay, but also the island has some of the most historic gardens in California. They were started by the military in the 1850’s on soil brought over from Angel Island, and then various soldiers, jailers, and inmates expanded and maintained the gardens throughout the years as the island went from fort to military prison to federal prison. The gardens were abandoned when the prison was closed down and a lot of the island was swallowed up by weeds, but a lot of the tougher plants held on. In 2003 the Garden Conservancy took over the gardens and began restoring them. Many, many, many hours of volunteer labor have gone into them. Restoration seems to be about developing or preserving the dichotomies of Alcatraz: a prison garden full of escaped exotics, a weeded garden ruin, wild plants in one of the most human-built sites in California.

There are a ton of different building materials throughout the island, with various types of concrete, stone, and brick mixed and layered in funky ways reflecting the island’s transformations from fort to military prison to prison. Even in the calla lily photo there are two different types of stone. The brickwork in the photo below almost looks like a tapestry the way it is outlined by what were originally the corners of separate stone walls.

I’m not sure what plants are naturalized from before and which ones have been added by the Garden Conservancy. There’s an extensive website for the gardens, including a blog, with a lot of photos and information about the history of the gardens. Quite a few garden bloggers have visited the island; Saxon Holt at Gardening Gone Wild, Far out Flora, and Oakland Guerrilla Gardener are two of the ones I know about.

This hand-carved granite doorway was built when the prison was still a fort. In the upper corners are two pulleys from the original drawbridge door.

Trillium ovatum

I don’t post about many garden events, but one of my favorites is coming up on Saturday, the native plant sale at Tilden. It’s their biggest event of the year with many great plants for sale, some of them quite hard to find. The rush to the Trilliums is the single most frenzied horticultural moment I know of. (Speaking of which, I don’t know if it has been my luck or some kind of bumper year for Trilliums, but I have seen more of them this spring than ever before. I’m curious if that has been anyone else’s experience as well.) The sale starts at 10AM, with people starting to line up about an hour beforehand.

Ready for Tomorrow

I went to the UC Botanical Garden yesterday. Anita and I decided to get memberships for the year. We realized that the garden is actually quite close to our house, not quite as close and convenient as the Tilden garden, but almost, and we should get to know it better. This was the first visit of the year. The garden was in transition between winter and spring, the earliest plants in leaf but most of the other deciduous plants still dormant.

The South Africa section has a new section of moss rock wall. Really nice stonework, dramatic contrast between the boulders and the walls. Be interesting to see what they plant, something with an intense flower no doubt, based on everything else in that section. I think it’s my favorite section of the garden.

It’s hard to think of a flower like this as the natural bloom and not a cultivar that has been bred by humans, but the UC has only wild collected seed.

I don’t remember noticing this vertical stone before. I think that’s a flowering quince behind it.

The ceanothus were going in the native section, but a lot of the other spring bloomers were just getting ready to break. Like the Tilden garden, the UC is a little later than my more coastal garden.

The Summer Holly, Comarystophylis diversifolia, was covered in buds. I’m not sure I’ve ever seen one in full bloom. The Oso Berry, Oemleria cerasiformis, is another one that I don’t often see in bloom.

And there is patch of Giant Coreopsis, the star of my recent bloom day, looking like they wandered over from the South Africa section. Such a strange plant; it’s very clear to me why I need one in my own garden and why I’ve never planted one for anyone else.

Last December I admired the aspens at Tilden, here and here, after they’d dropped their leaves. I told myself I should stop and check out their fall color this year, and I did actually follow through, stopping in several times to walk the garden while the aspens were coloring. They were nice, not quite like I saw in the mountains on my way back from Bishop but I give them extra points for doing it near the coast. In general, this doesn’t seem to have been one of our best years for color. I think the early storms knocked off a lot of the leaves as soon as they changed.

September

The aspens were definitely nice, though, and are of course great after they drop their leaves. I’m a fan of local natives, but it’s also great to see mountain species down here in the Bay Area. I’m lucky that my commute takes me past Tilden so regularly.

This Week

The aspens have been bare for a while now. Willows and spicebush are two of the main species coloring and dropping leaves there. In my own garden, the spicebush still has most of its leaves and even a couple of flowers and buds. I’m only five miles away, but in a less frosty microclimate.

Wildcat Creek

There’s one vine maple turned red. All the other fall color is yellow.

Vine Maple, Acer cirnatum

And along with fall color, November means that manzanita season is approaching. A few had token blooms, but this one was starting up its full bloom.

Parry Manzanita Starting Up

Townmouse recently mentioned the 2010 Fall Color Project that Dave at the Home Garden is hosting. He’s collecting and posting links to blogs around the country that are showing off their fall color. Click through to the kickoff post or to his front page to start with the most recent collection.

Here are the rest of my Ruth Bancroft Garden photos, mostly from my second visit to the garden, after the cold frames were taken down. Most of the plants outside of the cold frames are fairly common in Bay Area dry gardens these days, but I didn’t know a lot of the cactus species that had been under the frames. It was definitely worth the second visit to see them out of their plastic winter wrappers.

This photo and the next three are plants that don’t need winter protection in the Walnut Creek, so they were outside of the cold frames my first visit.

Even without the frames, there’s still a funky desert aesthetic created by some of the homemade staking.

The garden has some cool big yuccas.

This tree aloe was in the cold frame on stilts. Someone told me that in a single year they once lost 5 or 6 tons of aloes from a frost, hauling away whole dumpster loads of them.

NY Times and SF Gate did articles with photos of Ruth Bancroft and the garden when she turned 100 last year.

— The San Jose Mercury News has an article about some new work going on at the garden, with photos of the garden throughout the years.

I was interested in some of the changes in the Bancroft Garden as it evolves from a quirky private garden to a public one. For instance the entrance was moved from one side of the garden to the other, with a noticeable change in style. I suppose they couldn’t keep it, but there’s something to be said for an entrance that is just a giant agave and a mailbox with the name hand lettered in Sharpie.

The original parking lot was at the eccentric shade house/gazebo.

The better view of the structure is from the inside of the garden where there’s a flagstone patio.

The entrance and main parking lot were moved to the back of the garden so that there would be enough space for a tour bus to turn around. There’s a slick sign and planting on the street at the new entrance, but after parking you walk into the garden through a section that feels very much like the hinterlands; it took me a while to figure out that it actually was the hinterlands. Apparently, there’s a master plan in development that will change that.

The planting at the new entrance looks much newer than all the plantings inside the garden.

As soon as the property ends, the ivy starts. It’s hard to show with photos how completely the garden is surrounded by generic subdivisions.
