Snowball Viburnum
Showy Milkweed

Snowball Viburnum is a popular ornamental shrub with prolific flowering. This plant is prized for its round clusters of white flowers that resemble snowballs, delighting children and adults. In fall, its leaves turn vibrant shades of red.

Snowball Viburnum is sought after as a single accent shrub, but can also make a dense hedge or privacy screen.

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.
