Lupinus polyphyllus | Russell Lupine ‘Purple & Yellow’
Russell Lupine hybrids are perhaps the most popular named hybrid flower group in commerce today. They were developed in England by Yorkshire gardener George Russell in the early 1900’s, and are still today one of the worlds favorite wildflowers. Sturdy and majestic, Lupines are not only noted for their beauty, but also for their ability to thrive in challenging environments. The most commonly known and widely cultivated Lupine species, known for growing tall, lush, spikes densely packed vividly colored, pea-shaped flowers are known as Russell Lupine, or Garden Lupine. Its nectar & pollen rich blossoms attract bees by the bunches. Bumblebees are especially fond of Lupine.
Lupinus polyphyllus is an early season perennial that may take a year after planting to offer it’s stunning blooms, but will reward a gardener’s patience with abundant, colorful blooms the following year. If started early enough indoors there’s a good chance plants will bear tall, magenta-purple and yellow flower spikes during the first year in late summer.
Seeds grown from these plants will not be exact replicas of the parent plant, but will be similar in colors and appearance.
Lupine seeds can be planted in just about any region and any climate. For best results, grow in full sun in moist, but well-drained soil, and protect young plants from slugs and snails. Deadhead spent flowers to encourage repeat-blooms. Will self-sow. Excellent for naturalizing. Not bothered by deer or rabbits.
