Gwendoline Sweet Pea grows to an impressive 6-foot height on a slender 8-inch-wide frame, allowing you to pack substantial vertical color into tight spaces. The spring-to-summer bloom window spans five full months, providing extended fragrance and cut flowers for the home. Deer leave it untouched while bees and butterflies seek it out consistently, making it a low-maintenance bridge between spring and summer in the cutting garden.
Gwendoline Sweet Pea excels as a cut flower, with blooms that last well in the vase and release fragrance throughout a room. The tall climbing habit makes it superb for trellising against fences, arbors, and garden walls, where it can create a living screen of color. Many gardeners grow it specifically for succession plantings, harvesting regularly to encourage continuous flowering throughout the season.
