I took some more pictures at the UC Botanical Garden while I was there viewing the corpse flower. There’s a lot to see there. The garden is organized by region, like most botanical gardens, with an emphasis on mediterranean and low-water plants.

Dichelostemma volubile, Snakelily

Snakelily stem

I tend to think of the Tilden garden when I think of natives, but California natives make up about one third of the UC garden’s acreage, and the garden claims to have about one third of California’s native species represented, including almost all of California’s native bulbs. One I hadn’t seen before is a Snakelily (Dichelostemma volubile), a climbing bulb whose stems twine their way up through shrubs in the oak understory.

serpentine dry stack wall

Someone made a nice low wall of (I think) serpentine stone for the raised bed of serpentine plants. Serpentine, or serpentinite, is the state rock of California (though there is a languishing attempt to un-designate ti because it contains asbestos) and gets talked about in native plant circles because only certain plants will grow in serpentine soil. The stone is hard and smooth with a bluish or greenish cast to it; the white is from calcium. It’s rarely used for building in our area. About.com says that “serpentinite is a sexy rock.”

Southern Africa section

The Southern Africa section has some intense colors.

New World Desert section

The New World Desert section might be my favorite. The garden has a huge collection of cactus.

Knot Garden in the Mediterranean section

The garden has a great collection of palms near there, but I didn’t take any photos. I sometimes forget how nice palms can be, and even seeing them and realizing how cool the different shapes and varieties are, I still neglected to take a photo. Several more photos that I did take are below. (more…)

Trudy the Corpse Flower

You can catch flies with honey, but you can catch even more with the stench of carrion. I went to see Trudy the corpse flower blooming at the UC Botanical Garden in Berkeley. Corpse flowers (Amorphophallus titanum) earn that lovely goth name by exuding the stench of rotting meat to attract flies to act as pollinators, and they’re not shy about it. The smell is potent, Trudy filed the UC glass house with the smell of roadkill goat, and it’s effective, too; there were ten or twenty flies buzzing around it while I was there, and apparently there’s a bigger swarm in the morning when the smell is strongest. And it’s all a con job on the flies; they lay their eggs thinking there will be food for their offspring, but the children hatch and starve without a genuine carcass to feed on.

The flower is six feet tall and impressive even without the stench. Corpse flowers are from Malaysia and they take seven or more years to bloom, waiting until the plant’s corm weighs thirty pounds or more. The bloom, which is actually a collection of little flowers, has a claim as the biggest inflorescence in the world, and the spadix (the big spike sticking up in the middle) generates heat, up to twenty degrees warmer than the ambient temperature. Someone at the garden has a sensor set up to test if the plant gives off a biomagnetic field the way humans and animals do.

This particular corpse flower, Trudy, first bloomed in 2005 at age twelve, and then waited four years to bloom again, making this her second time blooming, though the garden has others which bloomed while Trudy was resting. The bloom will only last a couple of days before it gets pollinated and collapses. The garden’s website has tons of photos and regular updates. For years, we’ve been getting emails every time one of them blooms, but this was the first time I went by to check it out, and, I gotta say, it was pretty cool. There are seedlings for sale if you want to pay thirty dollars for an indoor plant that requires constant watering and feeding and smells like carrion when it blooms. Photos of nice-smelling flowers are below. (more…)

Paeonia californica, California peony

The California peony is blooming at the Regional Parks Botanic Garden at Tilden in Berkeley. I’d never seen one blooming before. To quote Las Pilitas, “You need perfect drainage, a very green thumb, and luck with this one.”

Deborah Small’s Ethnobotany Blog has a beautiful photo of one growing wild.

California Peony going dormant

Pt. Reyes meadow foam at the Tilden bot garden

Tomorrow is the Bringing Back the Natives Tour and I will be certain to visit two particular gardens on the tour, the Regional Parks Botanic Garden at Tilden and the Fleming garden, two of the states oldest and best gardens for California natives. The are great gardens on any day, and right about now is the time when they look their best.

The Fleming garden is the absolute must-see garden of the tour. It goes way beyond what is typical of a residential or native garden, and I think it’s especially interesting to also see the botanic garden on the same day. I don’t know exact history of either garden, but I do know that Jenny Fleming was involved with the botanic garden to some extent throughout the years, and her garden feels like a condensed, concentrated form of the botanic garden at a private home, with a lot of similar plants and combinations. Luke Hass, who does the maintenance for the Fleming garden, has a couple of articles about the garden on his website. RootedinCalifornia has some recent photos and the tour’s website has others. It’s an amazing garden that has to be seen in person to be appreciated.

meadowfoam and stream orchid

Both gardens are over fifty years old, which makes them unique places to see native plants used in Bay Area gardens. Often times on native tours it can be boring to see the same plants at every garden, but in this case it’s interesting to compare how the plants are used in the two settings. The naturalized plantings of meadow foam, Limnanthes douglasii, are a good example. In the Fleming garden it’s intermingled with stream orchid, Epipactis gigantea, while the Tilden garden has the yellow form, Pt. Reyes meadow foam, Limnanthes douglasii var. sulphurea, with Maianthemum. Meadow foam is an annual, but it’s growing in a way that only happens in a mature garden.

Partly as a result of seeing it at Tilden and the Fleming garden, I have it at my house as well, in the veggie garden in between some of the edibles and in our outer garden where it is growing up through the Snowberry, Symphoricarpos albus. It’s not the prettiest plant after it finishes blooming, while you wait for the seeds to form, but the flowers are charming and it combines really nicely with other plants.

Allium unifolium

We’ve been starting to add California native bulbs to our home garden and our landscape plantings, and so far, Allium unifolium is one of our favorites. A lot of the native alliums require perfect drainage and a summer dry period and would be difficult to source even if you thought you could get the growing conditions right. A. unifolium, though, is easy to find and grow; we read that it’s supposedly the most clay tolerant of the alliums, and so far that’s been the case. Also, because it’s considered garden worthy (the Dutch like it) and not just for native purists, you can actually find it in sufficient quantities to make an impact in a large garden, where it will spread somewhat aggressively if it’s happy. It’s beginning to bloom in several of our gardens now.

Allium unifolium in our garden

We were recently at the Regional Parks Botanic Garden at Tilden for their native plant sale, and I took pictures of the alliums that were blooming. The bed’s aesthetic (three foot high bed of stone holding 4-12 inch high plants) is more for collectors than for casual visitors, but it has some interesting stuff, of which Allium crispum sounds like the best bet to try in a garden. The Pacific Bulb Society has a good info page for North American alliums. Far West Bulb Farm also has photos and info and might be a source for some of them. I put photos of four alliums and the raised bed below. (more…)

Sing! by Mariposa Gardening and Design

We went to the San Francisco Flower and Garden Show (San Mateo Flower and Garden Show?) yesterday. This freestanding dry stone wall, by Mariposa Gardening and Design and John Shaw-Rimmington of the Dry Stone Walling Association of Canada, was the coolest feature in the show in my rather stone-oriented opinion. There’s something very cool about walking under a dry-stacked stone arch. They said about thirty people gathered around to watch them remove the form from underneath the arch during setup, and I saw a ton of people pose for for photos underneath it during the show.

Cool Living by Fiddleleaf Fine Gardening and Design

I also really liked the living wall by Fiddleleaf Fine Gardening and Design. The other green walls looked to me like they were grown horizontally and then put vertical for the garden show, but you could tell the Fiddleleaf wall was grown vertically from the way the plants oriented themselves. The construction details made me confident that it would actually be sustainable in the effort and resources to maintain it, and that it could evolve over time instead of being static. Green walls certainly seem to be the newest latest greatest; there were three of them in the garden show this year and it’s obviously an intriguing interesting idea, so I want to do some research into them. A lot of them seem to trade on the same novelty that makes Home Depot customers want to try growing a tomato plant hanging upside down in a bag, but I thought the Fiddleleaf living wall was the real deal, a beautiful sustainable feature for a small urban space.

Sky's the Limit by Rebecca Cole

“Look at this!” a woman beside me exclaimed when she saw the green walls in Sky’s the Limit, by Rebecca Cole, and I thought that captured the effect of seeing the tidy geometric mats of living wallpaper. Tons of novelty value, plants growing in a different way than you normally see. It’s impressive how well the shape in the painting matched the shape on the curtains, which matched the custom cushions, which matched the custom tiles. The garden swept most of the awards in the show, and it is the exemplar of a certain type of garden, the all-at-once garden, everything designed simultaneously so that everything matches, a perfect garden for the client who wants to write a check and then never change a thing.

The Return of Paradiso by Quite Contrary Garden Design

Similarly or in contrast to that garden, I’m not sure which, Quite Contrary Garden Design used found materials to make a cohesive whole. The materials all matched, but with the more casual roughness of flagstone, rather than tile. You could see that the designer collected the items, rather than designed them. I didn’t get to try out the wooden lounger, but I really liked how it looked.

There are photos already up on many of the designers’ websites, found through the garden show’s list of garden creators. BayAreaTendrils has photos, and I’m sure there’ll be more on other Bay Area blogger sites.

The show goes on for one more day, and the word at the show was that this won’t be the last year after all, that there’s a contract for five more years. Duane Kelly, the apparently-soon-to-be-former owner, has an interview at NestInStyle, talking about how the show needs to attract a new generation of visitors. It’ll be interesting to see what the new owners do to try to accomplish that.
