Only about five minutes elapsed between the first and second of these photos of the unfurling buds of sacred datura, Datura wrightii. I had no idea how quickly these things opened in the fading evening light as they get ready for their nighttime pollinators. Stand too close to these massive opening buds and you could almost get hurt!



There are times I’m sorry you can’t convey hover the internet how something smells. This is one of them. These massive eight to nine inch flowers can pump out so much scent every moth in the neighborhood comes for a visit. I usually think humans and insects don’t have an awful lot in common. But we definitely share an attraction to this flower’s amazing scent.
That’ll be the next photo project: setting up the tripod again in the dark, waiting for the moths, as I get intoxicated on the scent of the flowers…

The house behind us has a back fence that is about fifteen feet behind our rear fence. Between the two is a no-man’s-land of unmaintained iceplant, ivy and whatever else has escaped from the adjacent gardens. In some neighborhoods this might be the location for a back alley. But with lot of the back house rising six feet over ours, the land is too sloped to accommodate much more than a narrow concrete culvert to drain the slope behind us and keep the infrequent rains from inundating all of us below.

We have a gate that leads into this space of ambiguous ownership, but I’d never spent much time back there until a recent project to repair the fence.
I looked with contempt at the thick mat of iceplant. Botanical shag carpeting, I thought. Every ignored space in town is covered with it. It does next to nothing to provide habitat for the local fauna. Although it’s often planted to stabilize a slope, its weight can actually pull the slope down more than hold it in place. Yes, it’s very drought-tolerant, and it’s serviceable in some situations. But the plant for me usually represents a colossal failure of the imagination. We can do better than this.
I just happened to have two pots of seedlings of the native sacred datura, a.k.a. toloache, a.k.a. Datura wrightii. The plant easily grows six or more feet across, and I realistically had no space for it in the garden around the house. The lightbulb over my head came on.

It’s amazing what ten minutes with a trowel, a watering can and two pots of plants can accomplish. In this second photo, lower right, is one of the datura seedlings that I inserted into the thatch under the iceplant.
I must admit that after planting them I forgot to water them for almost a week of dry weather well into the eighties. Expecting to see carnage, I was surprised to instead see the plants looking at least as happy as they were in their seed pots. I gave them another drink of water, but that may be all they’ll require from here on out. Starting next spring, I’m hoping to bee able to see their amazing morning-glory flowers from my deck, unfurling at dusk to greet the night.
From my last walk in the local wilds I came home with a napkin folded around the seeds of another plant I previously didn’t have room for. I’m thrilled. I’ve got a whole new plot to garden.

In the local canyons, this time of year brings about the spectacular flowers of the sacred datura, Datura wrightii. The low, mounding bushes grow two to three feet tall and easily twice as wide, and are covered from dusk to mid-morning with immense white trumpets, easily eight inches across, often flushed with pale lavender.

This is one of several species of the genus that has been called toloache in Mexico. It’s in the nightshade family, and like other members of the genus Datura, the plant is as toxic as it is spectacular.
Even though it’s highly poisonous, some Native Americans used the plant as part of a ceremony marking the passage of a child to an adult. From the Wikipedia: “Among the Chumash, when a boy was 8 years old, his mother gave him a preparation of momoy to drink. This was supposed to be a spiritual challenge to the boy to help him develop the spiritual wellbeing that is required to become a man. Not all of the boys survived [my emphasis].”
On my recent pre-dusk hike through our local Los Peñasquitos Canyon Preserve all the buds on the numerous toloache plants were tightly furled when I arrived.
But by the time I left, less a half hour before sunset, the flowers buds were loosening. Had I stayed an hour longer I would have been able to view the fresh flowers in the last glow of daylight like an intoxicating evil welcoming the night.
Here you can get a sense for how large these flowers will be.
Despite its bad press this is one of our local plants that I’ve been eying to add to the garden. The only thing the cat shows any interest in are plants that look like grasses or catnip, and there are parts of the yard no small child could get to. Besides, I’ve already got a number of toxic plants in the garden–oleanders, tomatoes and other nightshade cousins.
In addition to having amazing flowers, this datura requires no added water during the long dry summer. Nothing this spectacular can make that claim.
Speaking of poisonous plants, last week’s New York Times had an article on the Duchess of Northumberland. She’s in the process of building a modern annex to grounds that were designed by Capability Brown, the landmark British landscape designer from the eighteenth century. Traditionalists are not happy. “They said I am to gardens what Imelda Marcos is to shoes,” the Duchess is quoted. In her project one of the features is the Poison Garden, which the article describes as “a spooky fenced-off area with about 100 varieties of toxic plants, as well as cannabis and opium poppies.”
I bet this duchess’s garden parties will be pretty interesting affairs…
