Mighty Chocolate Cherry Astilbe
Mighty Chocolate Cherry Astilbe
A Giant Astilbe with Chocolate Foliage and Cherry-Red Plumes
Mighty Chocolate Cherry Astilbe (Astilbe 'Mighty Chocolate Cherry') is a true showstopper, one of the largest astilbes available, sending towering cherry-red plumes up to three or four feet over dramatic chocolate-bronze foliage in mid to late summer. It commands attention at the back of a shaded, moist border and brings bold height and color where most shade perennials stay low. Deer-resistant and pollinator-friendly, it's a statement plant for Minnetonka, Lakeville, and Blaine shade gardens.

Best Time to Plant
Plant in spring or early fall, when cool weather and steady moisture help roots establish. Avoid midsummer heat.
How to Plant
Dig a hole twice as wide as the root ball and just as deep. Set the crown level with the soil, backfill with compost-enriched soil, water thoroughly, and mulch 2–3 inches deep to conserve moisture.
Watering
First Year: Keep the soil consistently moist, watering 2–3 times per week. This large astilbe especially needs steady moisture.
After Year One: Continue regular watering, especially in heat.
Drip Irrigation: A soaker hose or drip line provides the steady moisture this plant demands.
