Neon Flash Spiraea is a colorful, low maintenance, and multi-purpose shrub.

Late spring to fall you'll be drawn to its vibrant neon red blooms that rest on a neat mound of green foliage. If deer and rabbit are an issue on your property, consider planting Neon Flash Spiraea for its deer/rabbit resistance. Its tolerance of a variety of well-drained soils makes it an ideal foundation, landscaping, or border plant.

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.
