Aruncus dioicus – Goat’s Beard

General Information: Goat’s Beard, is a large shrub-like perennial that dies back each winter. Tall, wispy, feathery white plumes add interest and height to the landscape. As a functional native ornamental, this fast-growing plant is sometimes described as a tall ground cover which can smother invasive species and resists herbivores. A useful native companion or alternative to the widely-available Asitlbe plant, which has nearly identical growing requirements. Unlike Astilbe, however, the flowers of Goat’s Beard are rather fragrant and attractive to pollinators. This plant has medicinal uses amongst Indigenous Peoples. There are some traditional European dishes that feature Goat’s Beard, however we do not recommend eating this plant, as the leaves are known to contain toxins.

Cultivation Details: Blossoms late May through Mid-July. Slowly spreads via rhizome to form a dense patch over time. Add to the backdrop of a sunny hedgerow for a staggered compliment to other blooms, or use as a standalone hedge in shadier areas to keep out unwanted species. Works well as a specimen planting or mixed in with other shrubs, perennials, and pollinator plants. Does not out-compete grasses and can be mowed along with them in late fall. Goat’s Beard also can create a dramatic backdrop to a partially shaded area, foundation planting, or border, and is especially well-suited for planting in a woodland garden. Deer and rabbit resistant. Host plant to the Dusky Azure Butterfly.

Growing Requirements: Plant in partial to full shade. Plants may tolerate nearly full sun if kept adequately moist. Succeeds in clay, sand, or loamy soils. Prefers a rich, moist soil. Requires some moisture, will dry out during prolonged dry spells. Consider amending the soil with organic mulch. Tolerates a wide range of soil pH, from acidic to very alkaline.

Fun Facts: The species name dioicus means “having male and female flowers on different plants,” i.e. dioecious. Female plants are said to be slightly less showy than males. Note, these are unsexed plants. Seed will not be produced unless a male and female are present.
