Growing Information

Royal Navy Blue Sweet Pea thrives in full sun and well-draining, fertile garden soil. It is a cool-season annual that grows vigorously when supported by trellises or similar structures, using curling tendrils to grip. Regular watering is essential to keep the soil evenly moist but not waterlogged. Blooming occurs from spring to early summer, providing lush vertical growth and abundant flowers during the cool season.
