False Indigo

The new Towers series of False Indigos have been developed at Plants Delight Nursery to have an upright, narrowly vase-shaped habit. 'Blue Towers' features enormous flower spikes carrying large, periwinkle to lavender blue flowers in early summer. The flower spikes stand tall above the narrowly vase shaped clump of glacous green foliage. 'Blue Towers' will make a huge splash of color that will be the focal point of an early summer border.

Growing and Maintenance Tips

Baptisia grows best in full sun, though it tolerates light shade. If grown in too much shade, plants may require staking. Baptisia is easily grown in poor to average soil that is well-drained. Once established, it is moderately drought tolerant because of its tough, deep taproot. This perennial native may take a couple of seasons to become established, but is very long-lived once mature. Avoid disturbing established clumps.
