Vegetative Growth
12-24 monthsPlant develops multiple stems with increasingly larger, lance-shaped to ovate leaves that are opposite or whorled; stems may develop a reddish or purple hue
Ensure consistent moisture and partial shade. Fertilize lightly in spring with balanced fertilizer. Mulch to conserve moisture. Can take 2 years to reach flowering size.
Flowering
6-10 weeks (typically late July through September)Tall stems (4-6 feet) terminate in large, flat or slightly domed clusters of tiny pink, mauve, or purple flowers; foliage remains green and lush

Seed Development & Dormancy
8-12 weeks in fallFlower clusters dry and produce tiny seeds; foliage begins to yellow and decline in fall; plant dies back to the ground
Allow seed heads to remain on plant for bird food and self-seeding. Cut back dead stems in late fall or early spring (optional; many leave for winter structure). No watering needed once dormant.
Winter Rest
3-4 monthsPlant is fully dormant with no visible above-ground growth; dormant rhizomes remain in soil
