Tips for raising natural, water-wise lupin perennials from seeds and cuttings.
A favorite spring-time activity, growing lupine (Lupinus polyphyllus) provides flower gardeners with a wide and brilliant array of colors. Plants have stiff, erect flower spikes of 1-4 feet that emerge from horizontal foliage. Flowers are similar to those of peas or sweet peas and grow in large, crowded racemes of deep blue, purple, yellow, pink or white. Found growing wild throughout most of the northern United States. Short-lived perennial.
Easy to grow, lupine thrives in cool, moist locations. It prefers full sun to light shade and average soils, but will tolerate sandy, dry soil. Plants develop long taproots, so loosen the soil to a depth of 12-20 inches using a roto-tiller or garden fork. They will not grow in clay.
