Bush Monkey Flower
Mimulus aurantiacus
About Bush Monkey Flower (Mimulus aurantiacus) Nurseries Show All Photos The bush monkey-flower or sticky monkey-flower is a flowering perennial plant that grows in a subshrub form, native to southwestern North America from southwestern Oregon south through most of California and into Baja, Mexico. It grows up to 1.2 meters tall, has deep green sticky leaves 3 to 7 centimeters long and up to a centimeter broad and flowering stems that grow vertically. The flowers are tubular at the base and about 2 centimeters long with five broad lobes; they occur in a variety of shades from white to red, the most common color being a light orange. They are pollinated by bees and hummingbirds. The stigmas are notably sensitive and will close after being touched.

This genus has been subject to taxonomic debate. It is currently included in the Lopseed family but was previously in the Scrophularia. Some authorities prefer to list the genus as Diplacus. Within this species there are six recognized varieties that differ in flower size, color and other features.
