25 Gallery Yellow Lupine Seeds – Lupinus polyphyllus Perennial Garden Flowers

Gallery Yellow Lupine is a compact, well-branched perennial that produces dense spikes of bright yellow pea-like flowers in late spring and early summer. Its cheerful color and upright form make it a standout in perennial borders, cottage gardens, and meadow plantings, where it attracts pollinators and adds vertical interest.

Lupinus polyphyllus 'Gallery Yellow' is known for its uniform habit and reliable performance, typically growing 24–36 inches tall. The palmate foliage provides a lush backdrop even after bloom, and the flowers are excellent for cutting.

Planting & Care

Sow lupine seeds indoors 6–8 weeks before the last frost or directly outdoors in early spring after danger of frost has passed. Scarify seeds by nicking the seed coat or soaking in warm water for 24 hours to improve germination. Press seeds into moist, well-drained seed-starting mix and cover lightly with 1/8 inch of soil. Keep at 65–70°F; germination typically occurs in 14–21 days. Provide bright light and good air circulation to prevent damping off.

Transplant seedlings outdoors after hardening off, spacing 12–18 inches apart. Lupines prefer cool weather and may struggle in hot, humid summers. Water regularly during establishment and mulch to keep roots cool. Deadhead spent flowers to encourage rebloom and prevent self-seeding if desired. In hot climates, provide afternoon shade. Plants may be short-lived in zones warmer than 8 but often reseed.
