Smooth Aster
Beaked Sedge

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.

Beaked Sedge is a native perennial wetland plant that forms dense clumps of tall, grass-like stems. It produces distinctive beaked seed heads that mature from late spring into summer. The plant provides food for waterfowl, muskrats, and other wildlife, while its dense growth offers cover for birds and small mammals. Its flowers and seed structures contribute to pollinator and invertebrate habitat in aquatic ecosystems.

Thriving in saturated soils and shallow water, Beaked Sedge is common in marshes, fens, and riparian zones. Its rhizomatous growth enables it to spread into large colonies that stabilize soils and support overall wetland health. Hardy and low-maintenance once established, it is well-suited to riparian plantings, naturalization, and ecological restoration projects.
