False Indigo Bush (Amorpha fruticosa)
False Indigo Bush is a 6' to 10' tall native perennial shrub. It is a legume and grows best in medium to wet soils in full sun or partial shade sites. This plant features woody lower stems, branch stems with alternate leaves, and showy terminal spike-like racemes of small tubular dark blue flowers. It is usually found in wet ground along rivers, streams, ponds, ditches, swamp margins, and wet open woods. The plant does contain some indigo pigment and could be used as a substitute for wild indigo. This is an exotic looking plant often planted as an ornamental. It fixes nitrogen and the seeds attract numerous game birds and song birds. Prices listed are based on pure live seed weight, not bulk weight.
