LATHYRUS odoratus 'Knee High Mix' (Annual Sweet Pea, Semi-Dwarf - Knee High Mix) is a variety of sweet pea, which is an annual flowering plant. It is known for its beautiful and fragrant flowers.
As the name suggests, 'Knee High Mix' is a semi-dwarf variety, which means it grows to a compact height compared to other sweet pea varieties. Typically, it reaches a height of around 1 to 2 feet (30-60 cm) at maturity. 'Knee High Mix' is a sweet pea variety that grows as an annual plant. This means that it completes its lifecycle within a year.
This variety produces a mix of flowers in various colors, including shades of pink, purple, white, and red. The flowers are known for their sweet fragrance, making them popular for cut flower arrangements and gardens.
'Knee High Mix' sweet peas prefer full sun, although they can tolerate some light shade. They thrive in well-draining soil that is rich in organic matter. It's important to provide support such as trellises or fences for the plants to climb as they grow.
Sweet peas are usually started from seeds. They can be sown directly in the ground after the danger of frost has passed or started indoors a few weeks before the last frost date and transplanted outdoors. The seeds should be soaked in water for a few hours before planting to enhance germination. Regular watering, especially during dry periods, is essential to keep the plants healthy and blooming.
To encourage continuous blooming, it is recommended to deadhead the faded flowers regularly. This process involves removing the spent flowers to prevent seed formation and encourage the plant to produce more blooms. Applying a balanced fertilizer every few weeks can also promote healthy growth and flowering. Sweet peas typically bloom during the spring and early summer months. However, the exact blooming period may vary depending on your location and local climate conditions.
