The flowers have a sweet fragrance and are often used in floral arrangements.
Lathyrus odoratus is native to the eastern Mediterranean region. 'Mammoth Mix' is a cultivated variety selected for its long stems and diverse color range. It is commonly grown as an annual in temperate regions, completing its life cycle within one growing season.
'Mammoth Mix' typically blooms from late spring to summer, producing a profusion of large and fragrant flowers. The exact blooming period may vary depending on local climate conditions and growing practices.
Annual Sweet Peas like 'Mammoth Mix' prefer full sun exposure but can tolerate partial shade. They grow best in well-drained, fertile soil enriched with organic matter. Regular watering is necessary to keep the soil consistently moist, particularly during dry periods. These plants are often grown on trellises, fences, or other support structures to allow the vines to climb.
Annual Sweet Peas can be propagated from seeds. Sow the seeds directly in the garden bed in early spring after the last frost date. Soaking the seeds in water overnight before planting can help improve germination rates. Provide support for the vines as they grow.
Lathyrus odoratus 'Mammoth Mix' is primarily grown for its long-stemmed and fragrant flowers. The mix of flower colors adds beauty and variety to garden beds, borders, and containers. The flowers are also valued for their use in cut flower arrangements, where their scent and long stems make them suitable for floral designs.
Regular deadheading of spent flowers can encourage prolonged blooming. Providing support, such as trellises or netting, is essential for the vines to climb and prevent them from trailing on the ground. Adequate water and occasional fertilization with a balanced flower fertilizer can support healthy growth and flower production.
