The Perennial Sweet Pea, also known as the Everlasting Pea, is a charming, traditional herbaceous climbing vine that can reach heights of up to 10 feet. This plant showcases vibrant flowers during the summer months, with blossoms positioned on long stems that rise above the foliage. It utilizes tendrils for climbing and can be trained on trellises or used to adorn fences and other structures. Additionally, it serves as an attractive ground cover, effectively stabilizing slopes. The stems feature leafy wings, enhancing its decorative qualities. Notable characteristics include the winged stems and the ternately compound leaves, with the third leaf developing into a three-branched tendril. This plant thrives in full sunlight and well-drained soil. To propagate, soak the seeds in water for several days before planting them less than half an inch deep in early spring. It is worth noting that this plant does not respond well to transplantation and is generally free from significant pest issues.
