False Indigo
Amorpha fruticosa is a perennial shrub, often found at the water's edge and tolerating dry spells as well as occasional flooding. It prefers sunny locations but appreciates partial shade, particularly if the soil is on the dry side. Depending on the site, plants can grow up to 12 feet tall and will often spread by self seeding and suckers. False Indigo is a host plant for Silver-Spotted Skippers, Southern Dogfaces, and Black-Spotted Prominents. It also attracts Andrenid bees, which are specialist pollinators for Amorpha species. The flowers are a deep purple color with orange anthers, creating a beautiful and striking contrast.
We plant this nitrogen fixer as a companion plant near many of our keystone species. It serves as a chop 'n drop plant similar to Baptisia australis.
Arrives in a well rooted 3.5" x 5" pot.
