Common milkweed is more than just a garden plant—it’s a lifeline for monarch butterflies. It is the only food monarch caterpillars can eat, and the flowers provide rich nectar for many kinds of butterflies, bees, and beneficial insects.
The plants grow tall and upright, with broad green leaves and rounded clusters of rosy-pink flowers in summer. It has a bold, wild beauty that works well in natural gardens, meadows, and pollinator plantings.
It does spread by underground rhizomes, which can be a gift or a challenge depending on your space. In open areas or naturalized gardens, that spreading habit helps it fill in and create a true monarch habitat.
