Velvet-Leaf Milkweed
asclepias tomentosa
The Velvet-Leaf Milkweed (Asclepias tomentosa) is a resilient, sun-loving perennial herb native to the southeastern United States. Thriving in the harshest sandy conditions, this fascinating wildflower plays a vital role in coastal plains and sandhill ecosystems. Its common name is a nod to the soft, velvet-like hairs coating its stems and leaves, giving the plant a silvery-green shimmer in the bright sunshine. Like other members of the milkweed genus, it is famous for its milky, toxic latex sap and its ecological role as an indispensable host plant. It stands out with its uniquely pale, yellow-green to bronze flower clusters that bloom throughout the warm summer months. This species is a hardy survivor, well-adapted to wildfire-prone environments and nutrient-poor soils, making it an ecological anchor for countless native pollinators.
生息地: Found in dry, sandy upland habitats such as sandhills, scrublands, open pine flatwoods, and coastal dunes.
外見
This herbaceous perennial typically grows upright, reaching heights of 30 to 80 centimeters. The most distinctive feature is the dense, soft coating of short, woolly hairs on the stems and leaves, creating a velvety texture. Its leaves are oppositely arranged, lance-shaped to oblong, and often slightly wavy along the margins. The flowers, which cluster in terminal or upper-axillary umbels, display a subtle, pale greenish-yellow, cream, or bronze coloration with hoods that curve outward.

おもしろい事実
Its seeds are attached to silky, fluffy hairs called coma, which catch the wind like tiny parachutes to disperse over long distances.
Monarch caterpillars that feed on this plant store its cardenolide toxins in their own bodies, making them highly poisonous to avian predators.
The species name 'tomentosa' translates to 'covered with densely matted woolly hairs,' directly referring to its signature velvet leaves.
