Swamp Milkweed - White

Asclepias perennis, commonly known as aquatic milkweed or swamp milkweed, is a perennial plant native to the southeastern United States. It belongs to the milkweed family (Apocynaceae) and is known for its delicate, small white or pale pink flowers that grow in clusters. Here are some key details about Asclepias perennis:

Key Features:

• Flowers: Asclepias perennis produces clusters of small, star-shaped flowers, typically white or light pink. The flowers are known to attract butterflies, especially monarchs, as well as other pollinators.
• Habitat: As its common names suggest, it thrives in wet habitats such as swamps, marshes, and along streams and riverbanks. It prefers moist to wet soils and can often be found in areas with periodic flooding.
• Leaves: The plant has narrow, lance-shaped leaves that grow opposite each other on the stem. The leaves are smooth and have a light green coloration.
• Growth: It typically grows 1 to 3 feet tall. It's a relatively small species compared to other types of milkweeds.
• Importance to Pollinators: Like other milkweeds, Asclepias perennis is a vital food source for monarch butterfly larvae, which feed on the leaves. The flowers also provide nectar for adult butterflies and other insects.

Ecological Role:

• Asclepias perennis plays an important role in supporting pollinators, particularly monarch butterflies, whose populations have been declining due to habitat loss and other environmental pressures.

Cultivation:

• It is a desirable plant for pollinator gardens, particularly in wetter areas where other milkweed species might not thrive. It's often cultivated in gardens that mimic wetland conditions and is valued for both its beauty and ecological benefits.
