Background

Purple coneflower is the most versatile perennial in the cutting garden — the daisy-like blooms with their pronounced orange-brown domed centres are reliably beautiful from midsummer into autumn, the seed heads provide winter structure and bird food, and the plant itself is extraordinarily low maintenance once established. Native to the eastern US, it thrives in the conditions of the Hudson Valley without fuss.

Cut when the ray petals are fully open but before they begin to reflex backward. The central cone continues to develop after cutting and becomes a beautiful structural element in dried arrangements. Leave seed heads standing through winter — goldfinches rely on them.
