Centaurea cineraria from California-GS11022020-1

[Gurcharan Singh]

Centaurea cineraria L.

An interesting species which because of same common name "Dusty Miller" could be confused with Jacbaea maritima, but latter has broader leaf segments spread in single plane and yellow flower heads. The more closer species is Centarea gymnocara (often treated as synonym) with similar finely dissected leaves and similar purple heads, but are easily separated by involucre bracts which are narrower with suddenly narrowed fringed tip in C. gymnocarpa, broader with extended longer fringe.
