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.
