The sweet pea has long been cultivated as a decorative plant. The stems are delicate and weak, reaching a.height of 0.5-2 m; the leaves have a pair of leaflets and an axis, ending in a tendril that attaches to supporting objects. The tendril is branched. The blossoms are large and aromatic and grow in clusters. The magenta corolla grows up to 3.5 cm in diameter; cultivated varieties may reach up to 5-6 cm and have varying coloration. Sweet peas are used in gardens and parks; to decorate walls, enclosures, and balconies; and as cut flowers.
