37 Beautiful Texas Milkweeds (Asclepias spp.) to Grow for Monarch Butterflies

List of Texas Milkweeds

Texas Milkweed Species to Include in your Butterfly Garden

There are thirty-seven species of native Texas milkweeds (Asclepias spp.) that can be grown for Monarch Butterflies and other insects. Milkweeds are an important host species for Monarch, Queen, and Soldier Butterflies. The Monarch butterfly in particular uses the cardenolides found in the milky sap of milkweeds to give an unpleasant taste to predators. These plants are also an important nectar source to all insects visiting your pollinator garden.
