Allium dichlamydeum E. Greene grows near the coast in Northern and central California. The inflorescence is medium pink. The Flora of North America describes the bulbs as having a herringbone pattern. See the Flora's description of Allium dichlamydeum. The herring bulb pattern is on the bulb coat and this is often partly or completely missing if the bulb is dug up. The underlying bulb is white. Therefore the zigzag/herringbone pattern may not be readily apparent and in any case is more easily visible with a hand lens. Photo of bulbs by Ken Gilliland.
Since they grow on cliff faces where there is little soil, their bulbs do not bury very deep. It is one of the latest blooming of the Californian onions. These pictures by Bob Rutemoeller show it growing on the Mendocino Sonoma Coast in bud on a coastal bluff, in bloom in the same spot a few weeks later, and a close-up. The fourth picture shows it growing in a wild rock garden where it would be difficult for predators to get it, and almost two months after the first pictures in mid July 2003 it is still in bloom, now with Dudleya farinosa (Lindl.) Britton & Rose blooming at the same time. The final picture is a close-up of the two plants in bloom in another year.
Photo 1 below shows the plants growing in a raised bed in Mary Sue Ittner's garden. Photos 2-3 by Mark McDonough show two views of this species growing in his Massachusetts garden. Photos 4-6 were taken by Nhu Nguyen of plants growing in a small pot in California. The bulbs divide well and produces a wonderful show.
Photos below by RH. Photos three and four originally obtained as Allium falcifolium Hook & Arn. Photo four shows flowers going over and becoming pointier as they wilt, this had created some confusion for the grower.
