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.

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…)
