It is likely this is the first member of the Orobanchaceae that I ever knowingly encountered–a small patch of scarlet Indian paintbrush grew on the edge of some gravel pits about 10km from my childhood home. This species is perennial, so that patch is possibly still there if someone hasn’t torn up the rocky soil with an ATV or the like. I do remember being taken out by my parents specifically to see that patch on one or two occasions.
Castilleja has somewhere in the neighbourhood of 160-200 species, and almost all of these are in western North America. Castilleja coccinea is one of the exceptions, as it is broadly distributed across eastern North America. These plants, with their scarlet-red bracts, were photographed in early May.
