Regarding the question about red-flowered Trillium in California's Redwood National Park, I recently posted a query about the taxonomic status of Trillium kurabayashii, a red trillium from around the Oregon-California border commonly grown in gardens here in Portland. I learned that the name T. angustipetalum is now applied to populations in some parts of California, and CalFlora's website seems to imply that T. kurabayashii has been sunk in that name. I am growing a red trillium from Tuolumne County (one of the T. angustipetalum locales) and several "kurabayashii" from Portland gardens. The latter eventually grow larger. I received some very interesting private correspondence from Larry Neel, who sent me photos of a remarkable number of color variants of both red trilliums and T. chloropetalum that he photographed in the wild. It still isn't clear to me whether T. kurabayashii is a currently accepted taxon, or sunk in angustipetalum, or what the difference between the two is other than size and distribution. In any case, these two names cover any red trillium that might be in Redwood National Park, and T. chloropetalum appears now to be restricted to populations with sessile, whitish (greenish, yellowish) flowers and red-mottled leaves. The other western white trilliums do not have sessile flowers.
