Louisa, I have absolutely no idea. I have just purchase a book of 700 Ca. Natives ,and I cant find this one. It started up against that Yucca that is blooming and now this year, it is everywhere. It is a very attractive plant. I need to get a better picture. I think. Sedum sounds maybe like it could be it.
I agree with PoppySue, based on the picture, I'm guessing Helichrysum petiolare ("licorice plant"). It has very attractive silvery foliage with a velvety texture, and looks great trailing from baskets or planted among flowering perennials.
Popppy Sue and Go Vols , I say! I think you've got it!
The Licorice helichrysum , is close . It IS a variety of helichrysum. I looked on the "H" list on the link you provided Poppy Sue. And there are alot of other varieties.
The licorice variety has that large flower. This one has little flowers all over it. I think I will see if it will grow in a pot. It is a very attractive plant. Thankyou. I am going to search out the particular variety it is. Now that you have pointed me in the right direction. It helps , I think, if you have seen the flowers. Thanks Dave for moving this post to this forum too.
