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.

Canada Anemone is a native perennial wildflower known for its white, buttercup-like flowers. Blooming from mid-spring to early summer, it attracts a variety of pollinators, including bees, butterflies, and other beneficial insects. Its deep green foliage, characterized by deeply cut leaves with sharply toothed edges, adds texture and visual interest to the landscape even when the plant is not in bloom.

Canada Anemone grows naturally in moist meadows, forest edges, and riparian zones. Spreading rapidly through underground rhizomes, it forms large colonies that can help stabilize soil. It is well-suited to naturalization and restoration projects, including revegetating difficult, wet sites. Also suitable for rain gardens and pollinator gardens, but extra care and maintenance may be required to control its spread in smaller urban yards.
