HORTICULTURAL
Plant Sale Text: Swamp milkweed’s fragrant dusty-pink flowers attract butterflies in droves. Each intricate flower has five delicately curved petals. Swamp milkweed grows on the banks of streams and ponds, and in flood plains. It tolerates a wide range of growing conditions varying from standing water to soils that never completely dry out. Over time, its shallow rootstocks will eventually colonize an area. Milkweeds are a host plant for Monarch butterflies and supports up to 12 species of lepidoptera.
