Threadleaf Blue Star has very narrow needle-like leaves 3 to 4 inches long and only a matchstick in width giving it a fine, brushy look. The plant grows approximately 3-4 ft. tall here. The flowers are a medium dark steel blue in late spring. It prefers a dry-ish site.

Fall color is a good deep gold before the plants die back for the winter. This is a very attractive and dependable plant. Plus, it is deer-resistant.

Mine has never turned this brilliant yellow/orange in the fall. It's in full sun. Not sure why.

For best results (if planting more than one of these plants), space them at least 1 and a half feet apart from each other.
Landscape uses:
Plant bluestars singly or in small groups in the middle of a border. Willow amsonia does well in damp soil and is a good choice for planting by the side of a stream or pool.
