Seep Monkey Flower
Erythranthe guttata
  
About Seep Monkey Flower (Erythranthe guttata) 38 Nurseries Carry This Plant Seep Monkey Flower (Erythranthe guttata syn. Mimulus guttatus) is a perennial wildflower in the Lopseed family (Phrymaceae). As the name suggests, it grows in moist stream banks and seeps. Often it will grow with its roots submerged, and the light green foliage and yellow flowers will float on the surface of the water. Its spreading root systems make it one of the best plants for filtering water in aquatic gardens, and its abundant yellow snapdragon-shaped flowers add spectacular color to a pond in winter and spring. Note that because it aggressively spreads and copiously self seeds, it may need to be periodically pulled or cut back to prevent it from crowding out other plants.

Seep Monkey Flower attracts bees, butterflies and moths. Useful in naturally wet landscapes, such as a moist alpine meadow, along any sort of waterway, and in serpentine soils.
