From the southeastern U.S. Most of these elegant but tough plants, which resemble small shrubs, grow 2–3 ft. high and wide. Narrow leaves and erect stems are topped by clusters of small, star-shaped blue flowers in late spring. The plants look good all summer; their bright yellow fall foliage is a bonus. Bluestars thrive in ordinary garden soil and tolerate heat and some occasional lapses in watering. They look especially lovely when massed.
This award-winning plant is considered by many to be the finest of the bluestars. Its light green leaves are soft and very narrow, almost needlelike, and its fall color is an exceptionally bright, clear gold. Flowers are sky blue.Amsonia tabernaemontana
