Description

This outstanding, hardy perennial is perfect for beds, borders, and naturalized plantings. It forms eye-catching mounds of deep purple, nearly black foliage that brings high drama from spring to fall. Towering stalks of soft lavender and white bell-shaped flowers attract hummingbirds and pollinators. Extremely low maintenance and easy to grow, it requires no regular pruning, making it a worry-free choice for any landscape.

Plant Care

Water

Water regularly; allow soil to dry down between watering. Drought tolerant once established.

Fertilizer

In early spring, just as new growth begins to emerge, use a balanced, slow-release granular fertilizer like 10-10-10. Do not fertilize after mid-summer as it encourages tender new growth that will be killed by the first winter frost.

Pruning

Remove dead foliage in fall or early spring before new growth emerges.

Seasons of Interest

Dense mounds of dramatic deep purple foliage emerge, providing exciting contrast to spring-flowering perennials and evergreen shrubs.

Dramatic stalks of soft lavender bell-shaped flowers with white interiors bloom profusely in early and mid-summer. A high contrast and eye-catching addition to the summer garden.
