The Spencer type indicates large, ruffled petals that wave delicately in the breeze, and the Prince of Orange cultivar delivers warm, glowing color that no other sweet pea quite matches. At 6 feet tall with a compact 8-inch spread, this heirloom climber fits snugly along a trellis or fence without overwhelming a garden space. Deer steer clear while pollinators flock to the blooms, and the scent carries across the garden on warm afternoons.
Sweet peas are grown primarily as cut flowers, with Prince of Orange producing abundant blooms ideal for vases, wedding bouquets, and cottage garden displays. The flowers are purely ornamental and valued for their fragrance and decorative appeal rather than for eating.

Sow seeds in deep pots 4 to 6 weeks before your last spring frost, placing seeds at a depth of 1/2 to 1 inch. Keep the soil temperature between 55 and 65°F until seedlings emerge (expect sprouting within 5 to 30 days). Once seedlings have their first true leaves, move them to cold conditions outdoors to harden them off before transplanting.
Transplant seedlings out after they've been hardened off in cold conditions. Timing is flexible; many gardeners sow directly outdoors instead. Space plants 6 inches apart.
Sow seeds directly outdoors 3 to 4 weeks before your last spring frost, placing each seed at a depth of 1/2 to 1 inch. This timing allows seeds to germinate as soil warms and frost danger passes.
