Female monarchs lay eggs on milkweed host plants because their caterpillars only eat milkweed leaves. The plants’ sap makes the insects distasteful so that birds learn to leave them alone. This species is easy to grow, preferring full sun. It is drought-tolerant, and spreads via rhizomes and seed (remove seed pods in fall if desired). Its large flower ranges is pinkish-purple, and is sweetly scented to attract adult butterflies and other pollinators. This plant used to be much more common along roadsides and abandoned fields, but pesticides have reduced its prevalence.
