A Dwarf Native New England Aster in Deep Purple

Purple Dome Aster (Symphyotrichum novae-angliae 'Purple Dome') is a compact selection of our native New England aster, forming a tidy dome that disappears under deep purple, golden-eyed daisies every fall. Unlike the tall, floppy wild species, Purple Dome stays neat without staking while delivering the same magnetic late-season nectar that monarchs and native bees depend on. A must-have native for pollinator gardens in Edina, Maple Grove, and Woodbury.

Landscape Uses

Use Purple Dome in native and pollinator gardens, mixed borders, rain gardens, and naturalized areas. Its compact, self-supporting habit pairs beautifully with goldenrod, ornamental grasses, and sedum for a classic native fall scene.

Best Time to Plant

Plant in spring or early fall. Spring planting gives the longest establishment window before winter.

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, water in well, and mulch 2–3 inches deep, keeping mulch off the stems.

Watering

First Year: Water deeply 1–2 times per week to establish the roots.
After Year One: Water during dry spells. New England aster prefers average to moist soil and blooms best with regular water.
Drip Irrigation: A drip line keeps moisture even without wetting foliage, which helps prevent mildew.
