For those of you who can't get enough cool butterfly plants for your garden, you should really check out this interesting member of the Milkweed Family. The summer heat can never get too hot for this plant, as it is well accustomed to the weather of its native range in Southern Arizona and adjacent Mexico. Arizona Butterfly Weed, like all members of the genus Asclepias is a delight for the larvae of Monarch butterflies. Its flower clusters are purplish-white opening from buds that are pink. The very narrow leaves also give the plant a fine texture when used in flower beds or patio containers.
