Sweet Pea Queen of the Night Seeds is a heat-tolerant blend of fragrant heirloom sweet peas features stunning varieties like "Captain of the Blues" (mauve-blue), "Cupani" (maroon-lilac bicolor), and "King Edward VII" (deep crimson). These romantic flowers, with their rich colors and sweet perfume, are perfect for creating beautiful vine displays on fences or arbors. Plant seeds in well-drained soil, enriched with compost, and set up a sturdy trellis or support before sowing. In cool early spring, sow 1 inch deep and 2 to 3 inches apart, thinning seedlings to 4 to 5 inches apart. Sweet peas thrive in cooler weather and bloom best before the heat arrives, so plant early for the best results. Keep the soil moist and mulch to protect the plants as they grow.
