Lupin likes well-watered areas in order to grow properly. Sowing: February to June or September to October, at a depth of about 1 cm. Soak the seeds overnight before sowing and germinate at 20 to 30°C on the surface of well-drained, moist seed compost. They do well in sun or partial shade, but for the best flowering plants during the growing season, sow the seeds in a spot in full sun in well-drained, neutral to slightly acid, moist soil.

Soak the seeds for 24 hours or nick the seed coat. Lupin dislikes transplanting — sow in individual pots. Prefers acid to neutral soil.
