Thunderchild Flowering Crab
Smooth Aster

Thunderchild Flowering Crab is a hybrid crab apple known for its attractive and fragrant dark pink blossoms and deep purple mature leaves.

Tree farmers will find this hybrid appealing as a pollinator for other apples, while home growers will enjoy the red pome's ability to attract flocks of Cedar Waxwings in the early spring.

This species is reportedly resistant to fireblight.

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. As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.
