What a silly name this is! Sticky monkey flower, Diplacus aurantiacus (or Mimulus aurantiacus), is native to a broad range of ecosystems of California and the Northern Coast of Baja California. It is famously happy in situations that are too rocky or sandy for most other species. The resinous foliage really can be rather sticky during warm weather. The relevance to a monkey is a mystery.
Sticky monkey flower is more popular among hummingbirds and insects than anyone else. Those who welcome hummingbirds and insects into their garden happen to like it too. Honestly though, it might a bit too casual for refined landscapes. It works better in or on the outskirts of rustic gardens. If not already growing wild, cultivars and the straight species are available in some nurseries.
Bloom begins late in winter or early in spring, and might continue through summer, but is rarely impressively prolific. The bisymmetrical and tubular flowers are about three quarters of an inch long. Almost all are pastel orange, sort of like circus peanuts. Gold and yellow are uncommon. Supposedly, there are rare cultivars that bloom in red or white. Mature plants get more than three feet tall.
