Blue False Indigo is a low maintenance shrubby perennial that grows best in full sun exposure. Late spring to early summer the plant will become covered in bright blue flower spikes that grow up the clover-like foliage. The clean foliage holds an attractive blue-green color all summer. Once the flowers are spent, green seed pods develop that extend the season of interest for this perennial. The pods will dry to a black color that can persist well into the fall and early winter. This makes Blue False Indigo a wonderful, all-season plant. In some cases, such as partial shade environments, the plant may require staking when covered in the heavy blooms. It is tolerant of a mix of soil conditions, including drought and clay soil.
Blue False Indigo works best in borders, meadow gardens, naturalized gardens and as a specimen plant.
