Vacant lot, fenced for future construction, in bare finely compacted gravel of graded builing site, with Conyza canadensis, Hypericum perforatum. Taprooted perennial, appearing annual, with short curved white hairs throughout esp. upward, loosely compacted leafy basal buds, long few-branched leafy bracted inflorescence. Noted from several often dry and dusty sites in Greater Vancouver over the years. Unlike any native species, probably introduced from California. Often lumped with Epilobium ciliatum, but seems distinct in its hairiness at least. 100+ plants.
