The southernmost population of any Tillium, at least in western North America, is reportedly at Coon Creek in San Luis Obispo County. Here it grows in riparian woodland within a mile of the ocean (the surrounding hills are coastal sage scrub). This area is in Central California and provides hope that someday a cultivated strain may be adapted to Southern California. The flowers are red and can bloom as early as Christmas. This is T. angustipetalum (as treated by the Jepson Manual) and Robert F. Hoover (1970) makes this interesting observation: "It is remarkable that our plants have narrow petals like those of the remote Sierra Nevada, instead of being the broad-petaled form found northward in the Coast Ranges."
