Sweet pea is a cool-season climbing annual known for its vining growth and delicate foliage. It produces fragrant, butterfly-like flowers along slender stems during the growing season. This plant grows well in mild to cool climates and performs best in full sun with well-drained, fertile soil. Sweet pea establishes steadily and is suitable for garden beds, borders, and trellised planting, where it can climb and provide vertical interest.
