The individual florets may be of two colors giving the whole spike a two tone effect. A wide range of colors is available. Cut the flower stalks after the first bloom to encourage formation of a second spike. The plants prefer full sun but some light shade is tolerated. Lupine prefers moist, well-drained, acid soil.
Long taproots make transplanting difficult.
The seeds and seedpods are poisonous. The seed germinates in 3 to 4 weeks at 65 to 70 degrees and may need scarification. Start seed in peat pots to make the transplanting as easy as possible. The plants are divided in autumn but the survival rate is poor. This information is for educational purposes only.
