Scale-broom: Lepidospartum squamatum.
A very aromatic bloom in the sunflower family that attracts a wide variety of Lepidoptera, Hymenoptera, Diptera, Coleoptera, and Orthoptera. It has small scales on its stems instead of leaves in order to conserve moisture in a hot environment. This is not a spring wildflower; rather, it is a hardy shrub that blooms in the late summer and fall only. If you ever see this bush blooming it would be worth your while to stop and check it for insects. You never know what delights you will find.
