Here is another photo of an opening Spanish gold bloom, with both a solitary bee and a bee fly in it. Compare the antennae of the two, as well as how the wings are held. Flies have 1 pair of wings which are often held at any angle to the body at rest, while bees have 2 pairs of wings that are usually folded over the abdomen at rest. The antennae of flies tend to be very short, while bee antennae tend to be longer and often bent, fairly near the head.
This is yet another of those native plants that could definitely have a place in a garden setting. Its foliage is clean and has an interesting texture, being waxy, grayish green and having the leaf edges lined with little hairlike, soft bristles. The flowers are bright and pretty, and are attractive from before blooming through at least the end of the open blossom. Spanish gold requires no care and is well adapted to xeric conditions. Certainly worth consideration to see how it could be integrated!
So I'll leave you with a bright, sunshiny face to think about, the next time you pass by that plot of "weeds" - remember: it's only a weed if you think it is!
