Baccharis pilularus. Although I could be wrong since it’s usually an upright shrub. Smells like California.

Yes, baccharis. During an earlier let's plant this thing everywhere cycle in CA, the most used were the horizontal spreaders, such as 'Pigeon Point'. The spreaders are happy to get 3-4' tall, although they tended to be advertised as 2'ers. I'm not sure what cultivars are popular right now, as I haven't planted baccharis in many years. They have their place and use, and are very good at certain tasks, but I think they are rather boring.

Main problem being inconspicuous flower heads - one could plant for instance one of a number of low growing Ceanothus in the same situations and get its blue floral display.
