When I saw the blooms on Grindelia at the local native plant nursery, I thought it was beautiful and unusual. The centers of the opening flowers look like they have a dab of clear, glossy jelly on them. Bought one at 7.99 and it did well on my hot sunny bank. A couple years later I noticed gum plants growing along the roadsides of our town! Hmmm.

It is attractive and bright colored, unfussy..has spread to three or four plants after four years, slowly progressing down the bank. Deer don't bother it and I don't water it, so, I won't consider it a weed, but glad I only bought one!
