Canyon Sunflower is a rather large perennial with two inch yellow sunflowers. Canyon Sunflower looks like yellow dahlias on bushes. It seems to always be in flower. The foliage is succulent and tender but the plants are fairly drought tolerant and need little or no care. We have them planted in the nursery in high full shade, I would do the same in any hot interior climate. Along the coast I have seen it growing at the edge of oaks mixed with Salvia spathecea and Grindellia.
