Silky Lupine

Early Blue Violet is a low-growing native perennial wildflower valued for its striking early-spring blooms. The flowers range in color from vibrant blue to deep violet, often marked with pale highlights and fine white hairs. They provide an important early nectar source for pollinators and serve as a host plant for several fritillary butterfly species.

It spreads by both seed and rhizomes, gradually forming small colonies. Its dark green, heart-shaped leaves add ornamental appeal, and the plant shows some resistance to deer browsing. Early Blue Violet is well-suited to naturalization projects and pollinator-friendly gardens, and has also been used in coastal butterfly habitat restoration in the Pacific Northwest.

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.
