This unique species of milkweed is native to eastern North America where it is frequently seen growing along roadsides and in open fields. Its perennial foliage emerges each spring from a hardy tuberous root that withstands temperatures much colder than our Arizona winter lows. Surprisingly, butterfly milkweed’s herbaceous stems lack the milky sap that we often see in other plants of this family, but this species still enjoys the milkweed’s superior tolerance of heat, sun, and drought, as well as their resistance to the voracious appetites of rabbits and deer. Clusters of brilliant orange-red flowers will continue blooming throughout the summer, making this plant easy for birds and butterflies to spot from far away. Monarch butterflies are especially fond of milkweed, devouring foliage as caterpillars and then returning as adults to sip nectar and lay eggs.
