Amorpha fruticosa

Amorpha fruticosa (occidentalis) or False Indigo, grows in north slopes and moist spots through much of San Diego County, western Riverside county and cooler protected spots in Arizona and New Mexico. False Indigo is found in sheltered north slopes, canyon bottoms and along streams. Soils are fairly diverse and can be alkaline. Southern Dog Face butterfly larvae use the leaves of this plant for food. Plant in a part shaded spot that is cool, you do not find Amorpha on hot south facing slopes, but somewhere that you would want to set on a hot summer day. They like soil that doesnt dry out, but is not wet.
