Mimulus guttatus (Yellow Monkey Flower) is an annual or short-lived, spreading, mat-forming perennial boasting bright yellow, snapdragon-shaped flowers spotted with red on the lower lobes. Borne in succession from early spring to late summer, the showy blossoms are borne on leafy stalks in the upper leaf axils. They are pollinated by bees, butterflies, and hummingbirds. They contrast nicely against the foliage of soft, light-green, broadly rounded, and toothed leaves. Yellow Monkey Flower is a perennial in warm zones and a half-hardy annual in colder places. Yellow Monkey Flower spreads vigorously by seed and rhizomes. Putting on a show in wet, sunny places in the wild garden, this water-loving perennial is perfect as a ground cover for small, moist situations and is an excellent pond plant.
