Dear John, Our wiki page is a good reference: http://pacificbulbsociety.org/pbswiki/index.php/… Brodiaea californica is the tallest Brodiaea. californica is the species name, not a cultivar name and most authorities now place this genus in the Themidaceae family. It is usually lavender or violet, but occasionally pink or white. Telos sells a purple and a pink form. Many of our California native bulbs show wide differences in color, height, and form of the same species depending on where they originated. Not only that, but the same species can bloom at different times as well as there must be something in their genetic make-up that determines this. You can grow the same species from seed collected in different places and have plants that look different and bloom at different times. There is also a smaller version of this plant: Brodiaea californica ssp. leptandra There is good information on growing these plants in the new Wild Lilies, Irises and Grasses book edited by Nora Harlow and Kristin Jakob.
