Round-Leaved Sundew

Showy Milkweed is a native perennial wildflower known for its fragrant clusters of pink to purple, star-shaped flowers. It is an essential plant for Monarch butterflies, acting as a critical host plant for caterpillars and a nectar source for adults. Blooming from early to mid-summer, these flowers also supply nectar to many other pollinators, including bees, butterflies, moths, and hummingbirds.

Ideal for butterfly conservation, pollinator gardens, and naturalization projects, Showy Milkweed thrives in a wide range of soils, including dry and rocky ground. While it spreads via underground rhizomes to form colonies, it is much less aggressive than Common Milkweed (Asclepias syriaca).

Note: All parts of the plant contain toxic cardiac glycosides, especially the milky sap. Do not ingest any part of the plant and prevent sap from contacting skin or eyes. Toxic to humans, pets, and livestock.

Round-Leaved Sundew is a native carnivorous plant, easily recognized by its bright green leaves covered in distinctive red, glandular hairs. These hairs secrete a sticky substance that is used to attract, trap, and digest insects. Their carnivorous nature allows them to survive in nutrient-poor, acidic soils where many other plants may struggle to grow.
They produce small white flowers that grow along the top of a slender, leafless stem. They can be found growing in wetlands, most often among sphagnum moss, in consistently moist, acidic soils. It does best in cooler summer climates and is intolerant of shade. Due to its small size, the plant can be difficult to spot in its natural habitat. Round-Leaved Sundew is an indicator of healthy wetland systems and is valued in ecological restoration and conservation projects.
