Monkey Flower- Mimulus spp. (syn. Diplacus)

Because this 2-3 ft. flowering, semi-evergreen perennial develops a woody base it is considered a subshrub. Of the many native species, the named hybrids are showiest and most commonly available in nurseries. Native to coastal areas, monkeyflowers thrive in both partial shade and full sun, requiring little moisture but excellent winter drainage in nearly any soil. Deep green, sticky leaves fill thin stems that tend to flop as they elongate. To encourage density, prune once or twice annually in stages after bloom just above a pair of buds, never into bare wood. Tubular, lobed flowers nearly cover plants spring-summer in white, orange, yellow or red. Many showy hybrid cultivars are bi-colored. Often short-lived, plants may need to be replaced after a few years
