I only saw four gardens on this tour today. Here is the one that I liked, designed and maintained by Sequoiah Wachenheim and Jay Tidwell, owners and operators of Earthly Arts. This is their home garden.
The backyard is dedicated to food, including "raspberries, loganberries, mulberries, kumquats, Asian pears, pomegranates, and plums" not to mention all the greens and onions you see here:
They bought the property six years ago and pickaxed out the weedy back lawn. Thirty cubic yards of horse poop later, voilà.
A meditative side yard with a small lawn connects the front and back yards.
Note the yellow Chiranthodendron-type flowers floating in the water. Long-time readers may remember seeing the flowers of Chiranthodendron pentadactylon many times on this blog. That Latin American plant is cousin to California's Fremontodendron which you've also seen many times. The flowers in the pool are from a cross generic hybrid that you can usually find for sale at Dry Garden.
This side-yard used to be a rabbit run, but I overheard Ms. Wachenheim tell a visitor that the bunny was incompatible with their strawberry patch. Now bunny is only allowed out on supervised release. (They also have chickens of course.)
The ornamental front yard uses many of the plants you commonly find in contemporary Californian dry designs.
But I would say the kapok tree (Chorisia speciosa) is more common in Southern California. I recently drove by a mile of it on Santa Monica Boulevard in Beverly Hills.
Aeonium 'Schwarzkopf'--a lovely black aeonium. I've tried this plant a few times, and it always reverts to green! Which is, like, totally inexplicable to me.
