Lupinus
Lupins are easy to grow when planted in rich, well-drained, slightly acid soil in full sun to partial shade. Space 12"-18" apart, with the crown (point where roots meet the shoots) just below soil level. Mulch well to conserve moisture.
Lupine is not tolerant of hot summers. Water deeply during periods of drought. Cut back spent flower stalks to encourage a second bloom. Once planted, lupine does not transplant well.
Grows 12"-36" tall. Flowers late spring to early summer.
