Scarlet Monkeyflower
Erythranthe cardinalis
The scarlet monkeyflower is a spreading perennial herb most noticeable when in bloom. The fiery red-orange flowers have a deep funnel, apparently made of fused petals, the lower lip of which curls out around the funnel’s edge. The long, pollen-bearing stamens extend above the upper lip. The flowers, about 2 inches long, are born high above the downy, toothed leaves on long, sticky haired stems. The plant is composed of many mounding clusters of stems, reaching 2-3 ft when fully grown.
