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.
