Flora Norton Sweet Pea is a classic heirloom climber that reaches 6 feet tall and rewards patient gardeners with fragrant blooms from spring through summer. Named after the woman who bred this vibrant variety in the early 1900s, it produces flowers in a striking blue-purple shade that was revolutionary for its time. Sown in early spring, seeds germinate in 5 to 30 days and reach bloom in 84 days, filling a garden with delicate, ruffled petals and the honey-like fragrance that makes sweet peas irresistible to pollinators. Deer leave it untouched, and it thrives in full sun with moderate, consistent watering.

Flora Norton brought a breakthrough color to sweet pea breeding, and this cultivar bears her name as a living legacy. The blue-purple flowers emerge abundantly from spring through August when given full sun and cool-season growing conditions. At 6 feet tall, it's a serious climber that needs sturdy support but rewards the effort with weeks of fragrant blooms that attract bees and butterflies while standing firm against deer pressure. The 84-day timeline from seed to first flowers fits neatly into spring plantings across most zones, making it accessible to gardeners who plan ahead.
Flora Norton Sweet Pea is grown as an ornamental flowering vine, prized for its intensely fragrant blooms and the visual structure it brings to gardens. Gardeners grow it on trellises, arbors, and along fences to create vertical interest and to cut fresh flowers for indoor arrangements. The fragrance makes it particularly valuable in cutting gardens, where handfuls of blooms release their honey-like scent throughout a room.

Sow seeds 1/2 to 1 inch deep in deep pots 4 to 6 weeks before planting outdoors. Keep soil at 55 to 65°F for germination. Once seedlings emerge and before the first leaves unfurl, move pots to cold outdoor conditions to prevent legginess. This hardening process produces stockier, more vigorous plants ready for transplanting.
Transplant hardened seedlings outside 3 to 4 weeks before your last spring frost, once they have been acclimated to outdoor conditions. Space plants 6 inches apart in their final location. Ensure soil has been amended with 3 to 4 inches of compost and aged manure worked deeply in.
Direct sow seeds outdoors 3 to 4 weeks before your last spring frost. Sow seeds 1/2 to 1 inch deep and space them 6 inches apart. Prepare soil with 3 to 4 inches of compost and aged manure incorporated deeply.
Harvest flowers as soon as they open for the longest vase life. Cut blooms in the early morning when stems are fully hydrated. Pick flowers regularly throughout the bloom season to encourage continued flowering; removing spent blooms prevents the plant from setting seed and directs energy into producing more flowers.

“Flora Norton Sweet Pea carries the name of one of the most significant plant breeders in sweet pea history. Flora Norton worked in the late 1800s and early 1900s to expand the color range of Lathyrus odoratus, which had been a favorite of Victorian gardeners. She developed this distinctive blue-purple cultivar, a breakthrough at the time when sweet peas were primarily available in reds, pinks, and whites. The variety became commercially important and remained in cultivation as a named heirloom, a testament to Norton's contribution to ornamental gardening and her recognition as a pioneering female plant breeder.”
