Occurring widely in the northeast in thickets, open woods, and fields, Purple Milkweed is similar to common Milkweed except that it has much deeper rose-pink flowers and more pointed leaves. Plants form clumps 2 to 3 feet tall and wide and have stout straight stems topped by beautiful mid-summer rosy-purple flower balls. Butterflies LOVE their nectar and Monarch butterfly caterpillars love their leaves. Easy to grow in dry, poor to average soil, in full sun. Plants may seed and form colonies. (Sunlight Gardens)
