White Fringe Tree
Smooth Aster

White Fringe Tree is known for its fringe-like white flowers. It can either grow as a small tree or a large multistemmed shrub. The White Fringe Tree has separate male and female plants. Both male and female flowers have white fringe-like petals, but the male flowers are longer and showier. The female flowers give way to clusters of dark blue to black berries. These berries are not edible for humans but attract birds and other wildlife.

The White Fringe Tree is tolerant of clay soils, saline soils, and air pollution but does not do well in prolonged dry conditions.

Smooth Aster is a native perennial wildflower known for its violet-blue, daisy-like flowers. They bloom later in the season, from late summer to early fall. The flowers attract a variety of pollinators, including bees, butterflies, and other beneficial insects. It also serves as a host plant for the Silvery Checkerspot (Chlosyne nycteis) and Pearl Crescent (Phyciodes tharos) butterflies, further enhancing its ecological value. This easy-to-grow wildflower is well suited for native wildflower gardens, pollinator gardens, and naturalization projects.

The Smooth Aster’s non-aggressive root system allows it to spread slowly, and it is more likely to reproduce by seed, which can be controlled through deadheading.
