Silky Lupine
Rosy Lights Rhododendron (Azalea)

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.

Rosy Lights Rhododendron is the next flowering, deciduous shrub you need in your garden. It is incredibly cold hardy and produces fragrant, bright pink blooms in late spring. Pruning is recommended after the flowers are finished to control the size and shape of this shrub.

Try Rosy Lights Rhododendron when planning your next hedge/screen, or plant it on its own as a striking accent plant. Part of the Northern Lights Series.
