Botanical Name

AMSONIA hubrichtii

Plant Common Name

Hubricht's Bluestar

General Description

This plant is beautiful in spring, summer and fall. Hubricht's bluestar is a clump-forming herbaceous perennial grown for both its beautiful flowers and foliage. This native of Arkansas and Oklahoma is tough, clump-forming and can become quite large over time.

In spring, clusters of five-petaled starry pale blue flowers appear with the first foliage. The dense upright stems are densely lined with very fine green leaves. These offer a soft ferny appearance to the garden throughout the rest of the season. In late fall the leaves turn brilliant golden yellow and create quite a show.

Plant bluestar in full sun to partial shade and provide it with fertile garden soil. The clumps spread slowly over time and may need dividing every three to four years. This species is ideal for woodland gardens, foundation plantings and mixed borders.
