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.
