The Story

Plant Bio

Baptisia, or False Indigo, are robust, long-lived perennials that form an impressive shrub-like clump. They are valued for their attractive blue-green foliage, spires of pea-like flowers, and their extreme toughness and durability in the landscape. 'Indigo Spires' is a vigorous hybrid noted for its prolific flower production, featuring long, tapering spires of vivid indigo-violet flowers that are held well above the foliage. It has a vase-shaped habit and excellent presence in the garden.

Uses & Benefits:

Baptisia provides a commanding, shrub-like presence in the perennial border. Its spires of flowers are a major event in the late spring garden, followed by attractive blue-green foliage that remains handsome all season. The dark seed pods add winter interest.

As a nitrogen-fixing legume, it can improve the soil for neighboring plants. Its deep taproot makes it incredibly drought-tolerant and self-sufficient once established, making it a cornerstone plant for low-maintenance, sustainable landscapes.

The flowers are a vital nectar and pollen source for queen bumblebees and other large native bees. It is also a host plant for the larvae of several butterfly species, including the Wild Indigo Duskywing.
