Mock Orange
Smooth Aster

Mock Orange is an ornamental shrub known for its fragrant, white flowers. The scent is often described as orange-like with a hint of jasmine. Attractive to pollinators, hummingbirds, and humans alike.

Mock Orange is highly versatile, and can be used as an ornamental shrub, either alone or as a hedge. It is well suited for streambank stabilization and riparian zone restoration, due to its ability to grow in low, moist areas as well as those that are high and dry. Lewis Mock Orange also has the capability of being used in soil bioengineering projects such as live staking.

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.
