Lupine

Lupinus

Category: Flowers

Lupines bloom in late spring/early summer, in pea-like, elongated clusters and require a cool climate. Naturalized lupines are usually blue, white, or purple, but garden varieties can be vivid yellow, pink, red, burgundy. Lupines are easily identified by their palmate, silvery gray-green leaves. Lupines look best in pollinator, perennial, and naturalized beds and are an excellent cut flower.

Beneficial Critters

Growing from Seed

Soak seeds overnight or scarify to promote germination. Sow seeds in at least 32 cell tray or larger. Darkness aids germination.

Planting Considerations

Lupines will self-seed when they have found their happy place. Self-seeded young plants can be moved, but once established they do not like transplanting and are best left undisturbed. Roots are tender and plants started inside should be transplanted without delay. Note that most lupines are poisonous to humans and animals.

Harvesting

Harvest when 80% of blooms are open.
