The Lupinus polyphyllus, also known as the Big-leaved Lupine, Blue Bonnet, Garden Lupine, and Meadow Lupine, is a stunning perennial herbaceous plant with palmate leaves that grows up to 1.5 meters tall. It is native to Western North America and widely cultivated for its attractive blue to blue-violet flowers, produced in late spring/early summer on tall spikes. The Lupinus polyphyllus is easy to grow, preferring moist habitats and pH 6-8 soil. The species also has multiple varieties, including burkei, humicola, pallidipes, polyphyllus, and prunophilus. The Russell hybrids, derived from the Lupinus polyphyllus, have become increasingly diverse and are commonly used in gardens, with their vibrant colors ranging from reds to blues and are attractive to bees. However, the species can also be invasive, posing a threat to the endangered Karner Blue Butterfly due to hybridization with the butterfly's food plant. Overall, the Lupinus polyphyllus is a beautiful addition to any garden but must be carefully monitored to prevent any negative impact on local wildlife.
