Jump to: navigation, search

Variety candidissimum is a very attractive taxon with snowy, white-tomentose foliage and involucres and bright red corollas. It comes into contact with var. venustum in the North Coast Ranges of California, and individuals of some populations are difficult to place with confidence into either variety. Some plants of northern Nevada are also intermediate in their features between var. candidissimum and var. venustum.
