Upright Prairie Coneflower
Showy Milkweed

Upright Prairie Coneflower is a native perennial wildflower known for its vibrant flowers, which range from golden yellow to dark rust-red with yellow edges. Rising on tall, slender stems, the flowers’ drooping petals surround a central cone. They bloom from midsummer into fall, attracting butterflies, bees, and other pollinators. After blooming, the florets on the cone eventually develop into seeds, which provide a food source for birds.

Its upright growth habit allows it to grow in clusters, creating a striking display. Due to its deep taproot, Upright Prairie Coneflower is drought tolerant, making it well suited to dry areas and xeriscape gardens. Low-maintenance and deer-resistant, this wildflower is a great choice for adding vibrant color and ecological value to any landscape.

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.
