Calylophus hartwegii v. fendleri

Sundrops

Native to a large area of the Southwest and Plains, this mounding, woody perennial blooms during the spring and summer with large clear yellow flowers. These blossoms have a 24 hour life span, opening at night and fading to an orange-pink color by late afternoon. Prune back in early spring to remove woody or frost-damaged stems. Use in well-drained soil, and be careful not to over water. This plant is very susceptible to flea beetles, but they are easily controlled with common insecticides.
