This photo was taken 3-24-12 in San Francisco. It looks like a variety of liatris, but I can't find the specifics. It doesn't look like the spicata variety that I grow in Ohio. I've never seen this true blue-purple color before, and the shape is slightly different. If it's not a variety of liatris, what is it?
I agree with ecrane. It is the sound break for a neighbor's front yard. It is used in center dividers in town. Annie's Annuals sells a couple of varieties http://www.anniesannuals.com/plt_lst/lists/search/lst.srch.asp?prodid=385&srch_term=echium http://www.anniesannuals.com/plt_lst/lists/search/lst.srch.asp?prodid=2051&srch_term=echium
Yes, thatís it! Thanks so much. I've never seen it before, and the name is totally foreign as well. Interesting plant.
It's a passion flower (passiflora), but I don't know the variety. Start a new thread, and someone more knowledgeable will respond.
