About Common Milkweed

Common Milkweed is the quintessential powerhouse of the prairie, renowned for its incredible fragrance and vital role in the ecosystem. This robust perennial typically grows 3 to 5 feet tall (occasionally up to 8 feet), featuring broad, velvety leaves and large, drooping umbels of dusty pink flowers that bloom from June through August. Its sweet, honey-like scent can fill an entire garden, attracting a diverse array of bees, butterflies, and hummingbirds. Native across much of central and eastern North America, it is highly adaptable, thriving in full sun and various soil types from moist to dry. As a primary host for Monarch caterpillars, it is indispensable for supporting their lifecycle. While its rhizomatous nature allows it to spread aggressively—making it perfect for large naturalized areas—gardeners in smaller spaces should be mindful of its vigor. Seeds require a period of cold stratification to break dormancy, often best achieved by direct sowing in late autumn.
