Fire Light Hydrangea
Smooth Aster

Fire Light Hydrangea is a flowering shrub that is known for its striking colours. As they mature, the flower colour changes from a creamy white to a vivid deep pink. Hydrangea flowers persist longer compared to other flowering shrubs, blooming from late July into fall. They are a popular choice for flower arrangements.

The Fire Light Hydrangea can be grown as a stand alone shrub, as a hedge, or incorporated into a flower garden. Blooms occur on new wood, so regular pruning is encouraged in late winter. This is from the Proven Winners® collection.

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.
