Lupine plant care isn't complicated, and they're easily propagated by seed, as seen in their native habitats, where lupines cover hillsides with vibrant displays. In some varieties, the flowers are bicolor blossoms that pair a set of white petals with a second set in a primary color, creating a layered effect. Small pleated leaflets grow in rings around a central point, forming a cuplike shape. Hardy in Zones 4-9, lupine can be grown as either an annual or perennial, depending on the environment.

However, the deep South's heat and humidity (Zones 7-9) compromise lupines' well-being; grow these flowers as annuals in this area. In warmer climates, make sure lupines get light afternoon shade to cool things down. Lupines are traditional additions to a cottage garden and look lovely in a mixed border. The blooms make good cut flowers for arrangements. Cottage Landscaping Ideas for a Natural, Romantic Garden Style How and When to Plant Lupine While lupine perennials are easy to start from seed, these lupine plant care is challenging for overwintering when not grown in their ideal settings. The native species doesn't perform well as ornamentals in home gardens. Instead of growing wild lupines in home gardens, look for hybrids that thrive as cool-summer perennials, understanding that hot summer temperatures will end their flowering for the season. For a potted specimen, dig a hole about the same width and depth as the planting container. Remove the plant and loosen the roots a bit from the root ball before placing in the hole. Backfill with soil, tamp lightly, and water well. To plant lupine seeds outside, prepare the bed by scratching the soil. Scarify the seed and plant 1/4-inch into the ground and loosely cover. Keep the soil moist until you see germination, and continue to water regularly until the plant is established. Most plants will flower more profusely in their second seaason. Lupine Care Tips Lupine is easy to care for and requires little maintenance. Light Plants should be grown in full sun, which means at least 6 hours a day of direct sunlight, often on the south-facing side of a yard, for the best flower production and the sturdiest stems. Soil and Water Grow lupines in rich, fertile, slightly acidic, well-drained soil. To determine if soil has good drainage, dig a hole about 12-18 inches wide and 12-18 inches deep (it doesn't have to be exact). Next, fill the hole with water. Once it's drained, refill it with water and wait for it to drain again. The level should drop about an inch per hour in soil with good drainage. Soggy soil will result in root rot. If rainfall is lacking, water once a week. Temperature and Humidity Lupines like climates with summers on the cooler side. They don't do well in high heat and humidity. You can also reduce the temperature in root zones by applying mulch around the plant. How to Choose the Best Mulch for Your Landscape Fertilizer Fertilizing lupine may result in the overgrowth of foliage, reducing the flowering of plants. If the soil is too alkaline, use a specialty fertilizer to add acidity according to manufacturer's directions. Pruning Cut away dead branches to prevent disease spread, and cut back all foliage once it turns brown as the weather turns cold. During the growing season, deadhead spent flowers to encourage further blooming. Alternatively, cutting the plant back to half after its first bloom will also encourage new growth. Potting and Repotting Lupine Use deep, well-draining containers to pot lupine. Its taproots are long and need room to grow. Use lightweight soil to allow for good drainage. Water when the top 2 inches are dry and keep watering until a stream of water flows out of drainage holes. Repot when roots begin to grow out of drainage holes, but use caution when lifting the plants out of the container since the taproots are very delicate. Pests and Problems Lupines are susceptible to powdery mildew; good air circulation helps prevent this problem. Cut away affected leaves. If a plant develops a brown spot, remove it and destroy it. Lupine can be affected by common garden pests. Use horticultural soap to cleanse plants of aphids, snails, and slugs. How to Propagate Lupine You may benefit from self-seeding if you live in suitable zones and have the right environment for lupines in your garden. If the parent plants are hybrids, the seedlings will not come true, and you're likely to end up with various flower colors. Rooting side-shoot cuttings in late spring to early summer is more likely to be successful for propagating identical new plants. To propagate lupine: Propagate with cuttings in the early spring while the plant is dormant before it begins to leaf out. Cut a segment of the crown and roots from the plant using a clean, sharp knife.Plant the new segment in your chosen location.

The flowers are constructed with three upright "standard" petals and three drooping "fall" petals, which are often different colors. The falls may be "bearded" or not. Some cultivars bloom a second time in late summer. Zones 3-9 Jupiter's Beard Known as red valerian because of its rosy pink flowers, Jupiter's beard is one of the longest-blooming perennials in the garden.
