Asclepias curassavica or Mexican Butterfly Weed is a tropical perennial that is attractive to butterflies. They grow 2 to 3 feet tall and spread up to two feet. Plant them in full sun and this plant will bloom throughout the season with clusters of red orange yellow flowers atop the tall stalks. Butterflies of all types love to visit them. This plant is said to be somewhat drought tolerant. Hardy in zones 9-11, but commonly grown as annuals in cooler climates. Cutting back in the fall is recommended for zones where the plants live all year to ensure the health of the plants for the next year's butterflies.
