Erythranthe eastwoodiae is a Colorado Plateau endemic, growing in special areas that make it too vulnerable to collectors and sight-seers.

New plants are produced from stolons (runners) so that large areas are sometimes covered in E. eastwoodiae plants.  Flowers are about an inch long, scarlet to orange/red, and short-lived.

In 1911 Per Axel Rydberg discovered this lovely plant in Utah, and in 1913 he named it Mimulus eastwoodiae for expert botanist, Alice Eastwood.  (Click for more biographical information about Eastwood.)

Erythranthe is from the Greek "erythros", red, and "anthos", flower.

See Erythranthe for a discussion of the genus and genetic research.

Erythranthe eastwoodiae. Synonym: Mimulus eastwoodiae. (Eastwood's Monkey Flower)

Dried leaves persist from last year's growth as soft, hairy, young-green leaves unfold. Notice the tinges of red on the youngest leaves before chlorophyll develops.
