MONARCH JOINT VENTURE Partnering across the U.S. to conserve the monarch migration Plant Milkweed for Monarchs Monarchs cannot survive without milkweed. Monarch caterpillars need milkweed plants (Asclepias spp.) to grow and develop, and female monarch butterflies only lay their eggs on milkweed.With shifting land management practices, we have lost much milkweed from the landscape. Please plant milkweed to support monarch populations, and their incredible migration!onarch caterpillars need milkweed plants (Asclepias spp. ) to grow and develop, and female monarch butterflies only lay their eggs on milkweed.
