Calotropis gigantea (formerly Asclepias), commonly known as Giant Milkweed or Crown Flower, is native to Asia, but has become naturalized in many other locations, including Western, Central, and South America, the Caribbean, Brazil, and Australia. It is frequently found growing wild in dry coastal environments, and is a lowland plant that does not typically grow at elevations above about 1000 feet. The natural habitat is usually along roadsides and on previously developed lots and acreage. The plant is a fast-growing, soft-wooded, evergreen or semi-deciduous and matures as a tall, tree-like shrub with large, soft-textured, gray-green leaves with an odd, heart-shaped base and a hairy underside.
Clusters of unique crown-shaped, waxy, five-petaled flowers in multi-toned purples, lavender, and white are produced throughout the warm season and attract several species of butterflies, such as Tiger Butterflies (Danaus chrysippus), Monarchs (Danaus plexippus), and other pollinators. A fibrous, non-edible fruit-like seed pod follows the flower. Monarchs are believed to have the ability to utilize compounds from the flowers as a defense. The flowers are also frequently used for tassels, leis, and other decorations in some cultures.
The trunk develops a unique and interesting gnarled appearance, growing at odd twisted angles as if pushed by the wind or some unseen force, and is covered with a thick, corky, white to gray, furrowed bark. Branches exude a thick latex sap when cut or broken.
Giant Milkweed will grow in a wide range of well-draining soil types, is very drought tolerant once well established, and is also tolerant of salt spray. Plants are sensitive to cold and must be protected from frost and temperatures below 40°F. It can be grown as a large potted plant, but poorly suited for average indoor growing conditions.
