This forms a tall, upright clump of long green leaves, bearing clusters of rosy-pink, vanilla-scented flowers in mid-summer that are a magnet to butterflies! Certain types of butterflies also lay their eggs specifically on this plant, which the larvae use for food. Useful in the perennial border or wildflower meadow, and very easy. Seed pods are nice in dried arrangements, and may be picked just before they open. Fresh flowers are also cut, the ends of the stems must be seared over a flame to stop the sap from running.
