Bought one 4x4 inch plant 3 years ago. Put it in my dryish/native front garden (San Francisco). Beautiful blue flower heads. Has reseeded itself and now that I recognize the seedlings and have spotted them around it mixes well with the CA poppies, linaria, shirley poppies, meadowfoam and clarkia. Great plant.

I always try all plants in pots no matter what anyone remarks. This plant grew but was certainly lost among my other potted plants, frail foliage and flowers not very eye catching, even though I am trying it again this year 2009 to see if I can improve upon what I did previously, maybe mix it with something else to show it off, though it is in my mind a forgettable plant in a pot.. Perhaps has another better use. Nothing special but I am willing to give it (and me) another chance.
Has finely divided, mid-deep green leaves with linear leaflets. Bears heads of tiny light blue to almost lilac flowers with conspicuous stamens.
Flowers late April - August
Loves a well-drained soil in full sun but seesm to be tolerant of quite a wide range of conditions.
