How to Grow Lupine: Growing Lupine from Seed. Sow Lupine seed into a flower garden directly into a flower bed. Or, cast seed into an open meadow or field to grow as wildflowers. In the wild, Lupine grows best in acidic, well-drained soils. It prefers full sun, approximately six hours of good drainage, and well-drained compost.
To encourage lupine growth, Lupine flower seeds should be sown in warm, full sunlight. Once sown, keep seedlings in warm, dark areas for several days. If growing from seed, transplant seeds carefully about two to three feet apart. If using established seedlings, lightly cover them with potting mix before planting. Growing lupine from cuttings is a popular method for gardeners. Cuttings from young cuttings can produce striking, large lupine bushes in just a few years.
Plant lupines in spring, just before the flowers come out. Cool weather does not promote lupine growth. Keep in mind that certain colors do not grow unless the growing season is extremely long, such as the purple-blue. Growing flowers and lupines are not difficult, but you must know what to expect from each type of plant. Certain lupines and other plants cannot grow if the surrounding temperatures are too low.
There are two types of lupines: the common lupine plant, and the leaved lupine. The common lupine is a carpet type flower; the leaved lupine is a taller grass type flower. Both types of lupine have long blooming blooms that reach four to five inches. The color of the lupine flower depends on the type of flower grown, as well as the variety of lupine plant. Common lupine flowers include the pink, white, orange, blue, purple, freesia, and yellow varieties.
Many people grow lupine plants for the showy beauty they provide, however some people also grow these plants because of their exotic appearance. For this reason, it’s important to be sure you’re growing a true lupine, and not a cutting or hybrid. Cuttings and hybrid plants may still produce beautiful flowers, but the plant may not flower as well as a pure lupine would. For this reason, make sure you choose annuals or perennials over annuals when choosing how to grow lupine plants.
Growing lupine in acidic soil is a good way to increase its growth and bloom. Because of the blooming time of the lupine flower, many grow plants that bloom in cool weather – the warm colors are often created in cooler climates. If you live in a cool weather climate then you may want to move your lupine crop to a warm-weather location. If you move the plant to warm weather then the flower buds may not flower as lavender as you would like. This doesn’t mean you should move the plant, just move it closer to the warmer temperatures so the lupine will come out more in the spring.
One of the best ways to protect the life of the lupine is by planting cover crops around the base of the lupine. Cover crops are plants that stay relatively dry, like alfalfa or tobacco. These cover crops can help protect the roots of the lupine seeds by providing moisture to the soil where the seed is planted. Cover crops can also help protect the lupines from harsh winds. Make sure to plant cover crops far enough away so they can still have access to water when needed. If the lupine is placed too close to the edge of the soil then the wind can actually damage the lupine seeds.
As an alternative to the normal methods of how to grow lupine, there are also hybrid types of lupines that have become available to the growing world. Hybrid lupines are lupine plant that have been crossed with arctic lupines to create a new type of lupine that has some characteristics of both types of lupine. Hybrid plants are very popular and the prices for these are very affordable. If you cannot find arctic lupines in your area then you can try breeding lupines from Asian Lupine, which are able to tolerate lower temperature. But be sure to research breeding procedures thoroughly if you decide to use this method because some of these hybrid varieties can cause disease in your garden.
