Amsonia ciliata (Fringed bluestar)
Marcus, Joseph A.
The blue star plant grows 1524 inches tall. The leaves are borne singly, but very close together all the way up the stem to the flower cluster. They are 1/2 inch wide and 2 inches long, with one vein running lengthwise down the center and attached directly to the main stem (without a petiole). The leaves are smooth, soft, and slightly smaller toward the upper part of the stem. The narrow tube of the pale blue flower, 1/2 inch long, opens into 5 petal-like lobes in a star shape l/2 inch across, with a ring of white at the center. Several blossoms grow in a loose cluster at the tips of the stems.

Use Ornamental: Fringed bluestar is a long-lived perennial grown for its handsome foliage and spring flowers. The multi-stemmed clumps, to 3 ft. tall, are crowded with smooth, narrow, light-green leaves giving the plant a fine-textured, delicate appearance. Steel-blue, tubular flowers, the rim flaring to a star-shape, appear in loosely conjested clusters at the tips of the stems. The thin seedpods and golden fall foliage are additional attributes.
