A Bold Native Perennial with Creamy Summer Plumes

Goat's Beard (Aruncus dioicus) is a magnificent, shrub-sized native perennial that brings drama to the shade garden, sending up huge, feathery plumes of creamy-white flowers over mounds of fern-like foliage in early summer. Often mistaken for a giant astilbe, it thrives in moist, part-shade spots and makes a commanding backdrop or specimen. Deer-resistant and pollinator-friendly, this tough Minnesota native anchors woodland and rain gardens in Edina, Maple Grove, and Woodbury.

Landscape Uses

Use Goat's Beard as a specimen or backdrop in shaded borders, woodland gardens, rain gardens, and along streams and ponds. Its size rivals a shrub, and it pairs beautifully with hostas, ferns, and astilbes. The plumes are lovely for cutting.

Best Time to Plant

Plant in spring or early fall, when cooler weather and steady moisture help roots establish.

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. Give it room to reach full size.

Watering

First Year: Keep the soil consistently moist, watering 2–3 times per week.
After Year One: Water regularly, especially in heat. It prefers steady moisture and dislikes drying out.
Drip Irrigation: A soaker hose or drip line keeps the root zone evenly moist.
