Lupines come in a range of colors, including red, white, yellow, blue and violet. They grow up to 3 feet tall with small, pea-shaped blossoms growing clustered on the central stalk. Lupines grow in a variety of places throughout the United States wild and are easy to grow in gardens in most climates. One well-known variety of wild lupine is the Blue Bonnet---the state flower of Texas. Lupine are early summer bloomers, finishing their flower cycle by mid-summer in most varieties.

Step 1

Sow lupine seeds outside after the danger of frost has passed in your area. Choose a bed in partial to full sun. Dig the soil 6 inches deep to loosen it before planting.

Step 2

Sow seeds on the soil surface 10 to 12 inches apart. Cover the seeds with 1/8 inch of soil.

Step 3

Water until the soil is moist, but not soaking wet. Keep the soil moist at all times with one to two deep waterings a week.

Step 4

Fertilize with general purpose fertilizer once the seedlings are 1 month old and again at 2 months.

Step 5

Remove the flower spikes, or stems, once the blooms have faded to encourage further blooming. Cut the spike off at the base.
