Milkweed Giant

The Milkweed Giant, scientifically known as Calotropis gigantea, is a striking perennial shrub or small tree notable for its impressive size and unique flowers. Native to Southeast Asia and commonly found in tropical and subtropical regions, this plant is an essential part of many ecosystems, serving as a host plant for various butterfly species, particularly the Monarch butterfly.

Height: Typically grows between 6 to 10 feet (1.8 to 3 meters), but can reach up to 15 feet (4.5 meters) under ideal conditions.

Leaves: The leaves are large, opposite, and oblong, measuring up to 8 inches (20 cm) in length. They have a leathery texture with a pale green to grayish-green color. When broken, the leaves exude a milky sap, characteristic of the Milkweed family.

Flowers: The plant produces clusters of star-shaped flowers that are usually white to lavender in color. Each flower has five petals with a crown-like structure in the center, giving them a unique appearance. The blooms are fragrant and attract a variety of pollinators.

Fruit: The fruit of the Milkweed Giant is a large, oval-shaped pod that can grow up to 4 inches (10 cm) long. When mature, the pods split open to release numerous seeds, each equipped with silky, white hairs that aid in wind dispersal.

Native Range: Southeast Asia, but has spread to other tropical and subtropical regions.

Soil Requirements: Thrives in well-drained, sandy soils but is highly adaptable to a range of soil types.

Sunlight: Prefers full sun but can tolerate partial shade.

Watering: Drought-tolerant once established, but regular watering promotes healthier growth.

Temperature: Best suited for warm climates, being sensitive to frost. It can withstand high temperatures typical of tropical and subtropical regions.

Ecological Importance

The Milkweed Giant plays a crucial role in the lifecycle of several butterfly species, most notably the Monarch butterfly. It serves as a host plant for caterpillars, providing them with food and habitat. Additionally, its flowers are a source of nectar for various pollinators.
