Sweet Pea ‘Mammoth’ is a variety of sweet pea (Lathyrus odoratus) known for its large, fragrant flowers and vigorous growth. The ‘Mammoth’ variety produces large, ruffled flowers that come in a range of vibrant colors, including shades of red, pink, blue, lavender, and white. The flowers are known for their strong, sweet fragrance, making them popular in gardens and floral arrangements. This variety is a vigorous climber, capable of reaching heights of 1.8 to 2.4 meters (6 to 8 feet) with proper support. The plants have strong stems, making them ideal for cutting and displaying in vases. Sweet Pea ‘Mammoth’ typically blooms from late spring to early summer. With regular deadheading (removal of spent flowers), the blooming period can be extended.

  1. Growing Conditions:
    • Light: Sweet peas thrive in full sun, requiring at least 6 hours of direct sunlight daily.
    • Soil: They prefer well-draining, fertile soil with a neutral to slightly alkaline pH. Adding compost or organic matter can improve soil fertility.
    • Water: Keep the soil consistently moist but not waterlogged, especially during the growing and blooming periods.
  2. Planting:
    • Sowing Seeds: Sweet pea seeds can be started indoors 6-8 weeks before the last frost date or sown directly into the garden after the danger of frost has passed. Soaking the seeds in water for 24 hours before planting can help improve germination.
    • Spacing: Plant seeds about 2.5 cm (1 inch) deep and 5-7.5 cm (2-3 inches) apart. Thin seedlings to 15-20 cm (6-8 inches) apart to give each plant adequate space to grow.
  3. Support:
    • Provide a trellis, fence, or other support structure for the vines to climb. This helps prevent the plants from sprawling on the ground and encourages better air circulation, reducing the risk of disease.
  4. Care and Maintenance:
    • Fertilization: Apply a balanced, all-purpose fertilizer at planting time and again mid-season to promote healthy growth and abundant blooms.
    • Pruning: Regularly remove spent flowers to encourage continuous blooming and prevent the plants from setting seed.
  5. Pest and Disease Management:
    • Watch for common pests such as aphids, slugs, and snails. Treat infestations promptly with appropriate organic or chemical controls.
    • Ensure good air circulation around the plants to minimize the risk of powdery mildew and other fungal diseases. Avoid overhead watering to reduce leaf wetness.

By providing the right conditions and care, Sweet Pea ‘Mammoth’ can be a stunning and fragrant addition to your garden.
