Painted Lady Sweet Pea is one of the earliest named sweet pea cultivars, prized for its elegant bi-color blossoms featuring a rose backdrop with light pink fronts and retained fragrance. This heirloom variety grows 6 feet tall on a narrow 8-12 inch frame, reaching full bloom in about 84 days from seed. Hardy across zones 2-11 and frost-tolerant enough to direct sow as soon as soil can be worked, it thrives in cool-season gardens from spring through summer. Unlike many sweet peas, Painted Lady demonstrates notable heat tolerance, a trait that has made it a gardener's favorite since its Victorian origins.

The rose and light pink bi-color flowers are instantly recognizable and carry a beautiful fragrance that draws you back to the garden repeatedly. Early season timing means it blooms in the cool months when sweet peas perform best, and its superior heat tolerance compared to other cultivars keeps it flowering longer into warmer weather. Tall and elegant on its support structure, yet narrow enough to fit tight garden spaces, it attracts pollinators while remaining deer-resistant.
Sweet pea flowers are grown for cutting and arranging, bringing fragrant bi-color blooms into the home. The vine structure and climbing habit make it valuable for trellising and vertical garden design. Painted Lady's height and narrow profile suit it well to narrow beds, against fences, or trained on obelisk supports where the rose and pink flowers create visual interest throughout the blooming season.

Sow seeds indoors in deep pots 4-6 weeks before your last spring frost, keeping soil at 55-65°F until germination. Once seedlings emerge and before leaves unfurl, move them to cold conditions outside to harden off before transplanting.
Transplant seedlings outdoors after hardening off. Alternatively, wait to sow directly outdoors 3-4 weeks before your last spring frost, as soon as soil can be worked. Space transplants 6 inches apart with 9 inches between rows.
Sow seeds outdoors 3-4 weeks before your last spring frost, as soon as soil can be worked. Sow thickly since sweet peas only thrive in cool months; do not delay planting. Space seeds for 6-inch spacing between plants and 9-inch spacing between rows.
Deadhead spent flowers regularly to extend bloom through the season. Pinch out growing tips on young plants to encourage bushier vine development if desired, though the naturally narrow growth habit (8-12 inches wide) means extensive pruning is usually unnecessary.
