Exhibiting towers of vibrantly hued flowers, lupine plants add character to any sunny garden. Spires of showy, bright blooms reach 3 feet in length, making the lupine a stunning display that rivals other perennials for its sheer magnitude. Gorgeous in cut-flower arrangements, or plant them in groups along a fence or toward the back of borders. Popular varieties include dwarf lupine, Russell lupine. These vivacious, spiky flowers add structure and interest to any perennial planting or bouquet.
