Allium cratericola is a lovely little onion restricted to California. It is most often observed in the wild in Table Mountain in Butte County. The inflorescence stays appressed to the ground. In California, it tends to bloom much earlier than other onions, often times forming seeds by the middle of April. It can tolerate a variety of substrates including serpentine, volcanic, and granitic sediments. The key to cultivation is that the medium must be well drained with some organic matter. It likes being in full sun. Winter water is necessary, but a dry summer dormancy is extremely important. Photos by Nhu Nguyen. Photo 1-2 were taken at the Tilden Botanic Garden.
