Dwarf fritillary butterfly caterpillars on passion vine
In 21st-century California, it is increasingly a luxury of kingly proportions to have a yard of one’s own, especially within one of the state’s major metropolitan areas. As such, container gardening is the only option for many of us, a type of gardening that presents its own set of challenges, not the least of which being watering, as even the most drought-tolerant of plants will require much more watering in a container than they would in the ground. Maintenance reservations aside, I bit the bullet some months ago and started transforming the fire escape/balcony we have here in Oakland into a pollinator garden that is ideally groovy to look at and hang out in as well. To these ends, I planted, among other ‘tings, three kinds of passion vine back in April, hoping to attract the dwarf fritillary butterfly, whose food of choice is the passion vine. Well, as of a month ago, I discovered tiny orange eggs on the vines, and then two weeks ago, these eggs hatched into the tiniest of caterpillars. Since then, the caterpillar children have eaten to their hearts’ content and grown exponentially bigger by the day.
It would be a cliche to say that these are uncertain times we are living in, but, well, the cliche rings true. And in such uncertain times, inviting wildlife intro your landscape in whatever way possible can be a tonic to the lunancy about, serving as a small beacon of hope. What’s not to marvel over that a tiny butterfly would fly around and somehow locate a little patch of passion vine in the middle of dense, urbanized Oakland and decide to make that small patch of green home for its butterfly kids? It is marvel-worthy indeed.
A photo of Vacant Lands 1 in San Francisco’s Presidio
Here are the photos from the first Vacant Lands installation, installed in San Francisco’s Presidio as part of the Architecture as Pedestal Exhibition. Thank you to everyone who came by, asked questions, looked, explored, observed. We came up with the idea for the project in 2014, so it’s been a long road from conception to installation, and thus the support and interest were greatly appreciated. Naturally we already have our eyes and mind on the next installation, what it will look like, where it will be, and how you will be able to explore it. Stay tuned. For more info, you may click HERE.
We are spectacularly thrilled to announce that we will be doing our first Vacant Lands installation right here in San Francisco. The installation will be featured as part of the Architecture as Pedestal exhibition, which will be held on October 29 and 30 in the Presidio.

Lounging and observing the laboratory
The occasional sad reality of doing landscape design is that not all landscapes you create will survive long-term. Ownership can change, and maintenance can be spotty. At the very least, you can expect that some plants will die or be less successful than planned due to circumstances outside of your control, and the result will be a landscape different than what you had envisioned. In our case we never could have anticipated the bumper crop of rabbits that seemed to emerge in Minneapolis in the summer of 2009, or how that bumper crop would subside by 2014. Nor could we have anticipated how much the monarch and honeybee populations would dwindle during that same period. Fortunately, we’ve had a living laboratory of sorts in which to observe all of these phenomena long-term and to see what plants are bunny magnets, and which are monarch and bee magnets.
Here is our run-down:
Nepeta x faassenii ‘Walker’s Low’ / Walker’s Low catmint: Blooms for at least a month (reblooms after a mid-summer haircut), with the bees (bumble, honey, and solitary, not to mention hoverflies, hummingbird moths, butterflies, and hummingbirds) on it from sunrise to sunset
Aster oolentangiensis / sky-blue aster: Very good late-summer nectar/pollen source
Solidago speciosa / showy goldenrod: Also an ideal late-summer nectar/pollen source
Diervilla sessilifolia ‘Butterfly’ / Butterfly bush honeysuckle: Bumblebees love the little yellow flowers; lightly cut back after blooming for a second bloom
Perovskia atriplicifolia ‘Longin’ / ‘Longin’ Russian sage: Bees of all varieties love this plant, and it blooms from July virtually til the end of summer
Sedum ‘Autumn Joy’ / Autumn Joy stonecrop: Amazing late-summer nectar/pollen source
Liatris ligulistylis / meadow blazing star: They bloom, and the monarchs come. . . in droves; it’s as simple as that
Eutrochium purpurea / Joe Pye weed: Huge, tall, and full of monarchs once they bloom in July
Verbena bonariensis / Brazilian verbena: An annual that blooms from June (depending on when you plant it) until the end of summer and thus provides a very consistent nectar source for monarchs, which flock to it
Echinacea purpurea / purple coneflower: Numbers dwindled down to almost none by 2013, have replanted new ones and caged them
Panicum virgatum / switchgrass: Ultimately disappeared after two years and space taken over by other plants
Sporobolus heterolepis / prairie dropseed: Initially took a huge hit from the rabbits but now seems to be doing better now that it’s been in the ground longer (maybe rabbits don’t like crusty old grasses?)
Koeleria macrantha / June grass: Suffers some damage by rabbits each year in the spring, becomes less attractive to them by July
Rudbeckia hirta / gloriosa daisy: Numbers dwindled down to almost none by 2012; some that had self-sown in cages around other plants managed to survive, and now the landscape is full of them again (but there are also fewer rabbits now)
Liatris spicata / dense blazing star: Caged them and the rabbits have since kept away; landscape now dense enough that the plant has self-sown here and there, and the seedlings seem to be protected by other plants (that is a very loose hypothesis based on casual observation)
Aster oolentangiensis / sky-blue aster: Some were gnawed down to the ground and died; remaining ones caged and are now thriving and self-sowing with a bit too much aplomb
Liatris ligulistylis / prairie blazing star: A choice meal of rabbits of all shapes and sizes; the plants need cages around them if they are to survive a rabbit’s dinnertime whims
Just to be clear and in layman’s terms: bee and monarch magnets will bring you happiness; rabbit magnets, without the proper protection, will bring you sadness.
With all the rain this year, the cacti at the UC Berkeley Botanical Gardens are putting on quite the show right now. If you have never been, now is the time to go. Not only do you get to see these insanely huge cactus flowers live and in the flesh, but you get to experience sweeping views down a canyon and out into the Bay, with the Golden Gate Bridge just shy of the horizon. And there are newts o plenty swimming in the pond in the Asian Garden area. You will be stupefied by their gentle cuteness. What’s not to love?
