50 Black Knight Sweet Pea Seeds - Dark Purple Climbing Annual Flower for Trellis

Black Knight Sweet Pea is a classic climbing annual prized for its rich, dark purple blooms and intense fragrance. This heirloom variety produces long stems of deep maroon-purple flowers that are excellent for cutting and bringing indoors. The vigorous vines climb readily on trellises, fences, and arbors, adding vertical interest and old-fashioned charm to any garden. Black Knight is a favorite among gardeners for its striking color and reliable performance in cool weather.

Sweet peas are cool-season annuals that thrive in spring and early summer, or in mild climates during fall and winter. They prefer full sun to partial shade and well-drained soil rich in organic matter. With regular watering and harvesting of blooms, plants will continue to flower over a long season. Black Knight is a wonderful choice for cottage gardens, cut flower gardens, and anywhere its fragrance and color can be enjoyed up close.

Planting & Care

For best results, nick or soak seeds for 24 hours before sowing to improve germination. Sow seeds outdoors in early spring, as soon as soil can be worked, or start indoors 4-6 weeks before last frost. Plant seeds about 1 inch deep and 2-3 inches apart. Provide a trellis or support for the vines to climb. Keep soil consistently moist but not waterlogged. Mulch to retain moisture and suppress weeds.

Water regularly during dry spells and fertilize lightly if soil is poor. Deadhead spent flowers to encourage continued blooming, or cut stems for bouquets. Sweet peas are cool-season growers and may decline in hot summer weather. In mild climates, they can be sown in fall for winter and spring bloom.
