Description

This plant produces a stunning flower display in springtime. Flowers have dark purple petals and yellow centers with dark green foliage. Like most herbaceous perennials, on a non-irrigated green roof this plant can be susceptible to severe drought. It will benefit from a deeper soil profile or where the green roof media has been mounded. It will need regular water to become established. A mountain wildflower native to North America, this hardy plant is well suited for use as an accent on green roofs. Flowers attract many butterflies.
