Nursery contributed plant descriptions

Clouds of small gold to garnet centered flowers bloom early to late fall, attracting native bees by the score. Lovely in the garden bed, where is should be placed away from spreaders that might overwhelm this willowy beauty.
The fabulous Smooth Aster produces a profusion of deep blue, star-like flowers in late autumn after most other plants are long gone. Extremely hardy, it defies frosts and keeps on blooming, often well into November. A strong perennial, Aster laevis will grow in almost any soil. Hardy to Zones 4 - 8.
