| Description | This is one of the most effective native milkweeds for attracting both caterpillars and mature Monarch and Queen butterflies. The caterpillars will feed on the foliage but usually not heavily enough to hurt the plant, and the butterflies will visit it for nectar and to lay their eggs. Arizona Milkweed has a limited distribution in the state, preferring moist, shaded canyons in southeastern Arizona. In cultivation this species benefits from regular supplemental irrigation, and will reward the gardener by flowering prolifically and attracting pollinators. In moist beds Arizona milkweed is prone to reseeding. |
