Amsonia illustris

Prairie Blue Star

Steel blue flowers. Shiny willow-like leaves turn bright gold in the fall.

Growing & Maintenance Tips
Full sun to partial shade in a moderately fertile soil. Amsonia should be massed for optimum effect. The cool blue flower color does a good job of toning down adjacent flower colors in the border. It can be used in the front or the middle of the border.

Interesting Information
Amsonia for Charles Amson, an 18th century physician in Virginia.
