Native to Baja, California and Sonora, Mexico, this evergreen vine has smooth, rounded green leaves. Bright yellow, orchid-like flowers adorn the plant in spring and summer. If not supported, this plant will twine on itself to produce a mounding shrub or even a groundcover. This plant is fairly drought tolerant once established, but will appear more lush with regular summer watering. Sensitive to hard frosts, this plant will recover slowly in the spring.
