Planting & Care

Sow Persian Slipper Lupine seeds indoors 6-8 weeks before the last frost, or directly outdoors in early spring or fall. Scarify seeds by nicking the hard outer coat with a file or sandpaper, then soak in water for 24 hours before planting. Press seeds into the soil surface and cover lightly with 1/8 inch of soil, as light aids germination. Keep soil moist at around 65-70°F (18-21°C); germination typically occurs in 14-30 days.

Once seedlings have several true leaves, transplant outdoors after hardening off. Space plants 12-18 inches apart in a sunny location with well-drained soil. Water regularly during dry spells, but avoid overwatering. Mulch around plants to retain moisture and suppress weeds. Deadhead spent flowers to encourage additional blooms and prevent unwanted self-seeding. In colder zones, provide winter protection with a layer of mulch.
