Doellingeria umbellata

Common Name: Flat-topped Aster

Flat-topped Aster is a tall, late-blooming perennial that grows 2 to 7 feet high, featuring clusters of small white flowers with yellow centers from late summer to fall. It thrives in moist meadows, wetlands, and woodland edges, preferring loamy or peaty soils. This plant attracts butterflies and bees, making it a valuable addition to pollinator gardens. It is commonly used in wetland restorations, rain gardens, and naturalized landscapes where it provides late-season nectar for insects.

Sowing Information

For most homeowners, the recommended method is to hand-broadcast seed at a minimum rate of 16–64 PLS (Pure Live Seed) ounces per acre. To ensure even coverage, broadcast the seed in perpendicular passes across the site. Grass seed should be broadcast first and lightly raked into the soil. Afterward, apply a light mulch layer using clean, seed-free straw or, preferably, our native Little Bluestem straw, available at our retail garden centers. Once mulching is complete, broadcast native wildflower seed over the area without raking it in. A good rainfall or thorough watering will provide sufficient soil contact for successful germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
