Plant Type: Perennials
Tall, upright stems bear loose racemes of small, double, deep blue flowers with a silver gloss. Starts to bloom in early summer and continues through late summer if spent flower stems are removed. A strongly, upright habit; clumps increase in size by producing shoots which arise from the base of the plant. Forms rosettes of dark green, narrowly lance-shaped, evergreen basal leaves.
Growing & Maintenance Tips:
Keep the soil moist but make sure it is well-drained. Members of this group will grow in either full sun or partial shade, though some shade is recommended in areas with very hot summers. The delicate flower colors are best preserved with some shade. Taller varieties may require staking. Cutting the plants back hard after flowering will keep them more compact and will help to prevent self-seeding. This action may also result in a second flush of blooms.
