How to Plant Lupins


There are between 200 and 250 species of Lupins, some annuals and some perennials. They have tall spikes from which pea-like flowers grow in many colors. There is also a tree Lupin that is not really a tree, but an evergreen shrub that can grow up to six feet tall. The flowers on both plants are very fragrant and make wonderful additions to English gardens. Lupins are easy to grow and care for and will give you an entire summer of beauty and scent.

Step 1

Dig the flower bed down about three inches and work an inch of compost into the loose soil.

Step 2

Plant annual seeds 1/4-inch deep and about 12 inches apart in the soil. Choose a sunny to partially shady location after the last threat of frost. Perennial seeds should be soaked in warm water for 24 hours before planting 1/2-inch deep and 12 to 36 inches apart, in a similar location in the fall.

Step 3

Water to moisten the soil immediately after planting. Keep the soil moist for annuals and start to water perennials in the spring. Do not soak or allow the seeds or seedlings to stand in water.

Step 4

Once the flowers are established, fertilize with a high-phosphorus, water-soluble fertilizer. Fertilize once for annuals, mid- to late summer, and twice for perennials, mid-summer and again in the fall. Follow manufacturer's directions as to amount to use.
