Planting and Care Guide

Planting Tips

Plant in average to lean, well-drained soil. Space 12–18 inches apart. Water thoroughly after planting. Penstemon prefers lean conditions- avoid rich or consistently wet soils which cause weak growth and reduce hardiness.

Care Tips

Water regularly after planting; once established it is quite drought tolerant. Deadhead spent flower spikes to encourage a second flush of bloom later in the season. Cut back to the basal foliage rosette in late fall. Divide every 3–4 years in spring. Largely pest-free and deer resistant. Excellent for pollinators. The clear blue tubular flowers are produced over a long season and are outstanding for the front to middle of a sunny border.
