Baptisia Indigo Spires

False Indigo

This deep blue Baptisia is a very compact variety with a perfect habit and heavy flower production. Unlike some Baptisia which can be tall and leggy, 'Indigo Spires' forms a densely branched, fully rounded clump of glaucous green foliage that extends far down the stems, leaving little bare stem showing at the base. In early summer, long spikes of deep violet purple flowers accented by a yellow keel are borne on all sides of the rounded clump, not just at the top, producing a bigger show of color overall. Secondary flower spikes extend the flowering time into midsummer.

Growing and Maintenance Tips

Baptisia is a low maintenance perennial that is extremely disease resistant. It is adaptable to a wide range of soil types but prefers average to dry, well drained soil in full sun. It can handle a couple of hours of shade but will be floppy in too much shade. It is very tap rooted and, once established, should not be disturbed. Old foliage should be cut down in the fall because the plant is unattractive once frost hits. Dividing this plant is not recommended.
