In late spring to early summer, periwinkle blue flowers cluster at the stem tips of this long-lived perennial creating a delicate contrast with light green, feathery foliage. By midsummer the plants give the impression of billowing clouds melding with the surrounding landscape. Native to the southeastern United States, Amsonia ciliata is one of the best clump-forming perennials for fall color, shining a radiant bright yellow before going dormant for the winter.

- Culture Notes
- This long lived perennial prefers a rich well-drained soil and regular summer watering. Plant it in full sun for the best flowering and brightest fall color. Be patient with new young plants, often they can look a little straggly and forlorn and may take a few years to fill out. To help plants establish give them some space to minimize competition. Once they mature they will be long lived and robust, full specimens.
- Geek Notes
- Native to North Carolina and south to Florida then west through Missouri, Arkansas and Texas.
