Common Milkweed (Asclepias syriaca) is widely known as a host plant for Monarch Butterflies. Once found in a wide range of sites, milkweed has been in dramatic decline in recent years. Common Milkweed spreads readily by seed or rhizomes and its long tap root helps to withstand drought. Planting even a small patch of these stunning pink flowers in your garden can help the Monarchs!   Light: Full Sun, Part Sun Moisture: Medium to Moist Soil Type: Well-Drained, Sandy, Loamy, or Clay Soil pH: 6.0-7.5 Average Height: 1-4 Feet Flowers: Light pink to lavender in color, ball-shaped clusters (umbels) of small, downward-pointing blossoms Bloom Time: June–August Native Region: Eastern North America Wildlife: Monarch Butterflies and Milkweed Tussock Moth
