Snowball Viburnum

Silky Lupine is a native perennial wildflower known for its upright spikes of blue to violet flowers. Blooming from late spring into summer, the nectar-rich, showy blossoms attract a variety of pollinators, especially bees and butterflies. The plant’s fine, silky foliage provides soft texture and visual interest, enhancing landscapes throughout the growing season.

Silky Lupine is a nitrogen-fixing plant that enriches soils and supports surrounding vegetation. Its deep roots stabilize soil, and it spreads naturally by ejecting seeds from drying pods. If spread isn’t desired, new seedlings are easy to remove. While it is foraged by some wild animals, it contains alkaloids that are toxic to livestock. Silky Lupine is well-suited to pollinator gardens, naturalization plantings, erosion control, and ecological restoration projects.

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.
