Lupines grow and bloom best in full sun, with at least six hours of direct sunlight on most days. They can tolerate mild shade, although blooming will be reduced.
Lupines prefer cool temperatures and moist, sandy, well-drained soil. They grow best in soil with a pH that is neutral to slightly acidic, but they can also grow in very acidic soil.
Keep the soil evenly moist after planting lupines to encourage good root development. But remember that lupines don’t prefer soggy moil as overwatering can lead to root rot.
