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 Mint is a native perennial plant known for its fragrant edible leaves. It produces small white to purple flowers in clusters around the stem and is commonly found in wet areas, including ditches and along wetlands, lakes, and rivers. The leaves can be eaten fresh or used to make teas and essential oils.

Canada Mint can spread quickly through underground rhizomes, making it well-suited to naturalization and restoration projects where it can spread freely. In smaller urban yards or gardens, container planting is recommended to help manage its growth. If planted directly in the ground, regular care and maintenance may be needed to limit its spread.
