Lathyrus odoratus 'Mammoth Mixture' – Extra large, wonderfully scented sweet pea flowers in a colorful mixture

Lathyrus odoratus 'Mammoth Mixture' is a particularly popular blend of annual sweet pea varieties known for their extra-large flowers, abundant blooms, and especially their intense, classic sweet pea fragrance. This mixture features various colors—ranging from soft pink, lilac, white, red, burgundy, and purple—transforming any garden, border, or flower box into a vibrant, romantic display of color. 'Mammoth Mixture' is among the most powerful and impressively scented sweet peas and is particularly popular for both garden planting and cutting fragrant flowers for bouquets.

Large-flowered, classic sweet peas with a strong scent

The name 'Mammoth' says it all: this mixture consists of sweet pea plants with extra-large flowers, often larger than those of standard Lathyrus odoratus varieties. The flowers have wide, wavy petals, giving them an almost luxurious appearance. This selection is also known for its strong, sweet fragrance, which is especially beautiful on warm evenings. Flowering runs from June to September, allowing you to enjoy months of color and fragrance in your garden.

Ideal as a cut flower

One of the greatest advantages of Lathyrus odoratus 'Mammoth Mixture' is that the flowers are exceptionally suitable as cut flowers. Regularly picking encourages the plant to produce new flowers, resulting in an even longer flowering period. The stems are long, sturdy, and straight, perfect for fragrant summer bouquets. Moreover, the flowers last a long time in the vase and fill the room with their classic sweet pea fragrance.

Climbing plant for borders, fences and pergolas

Lathyrus odoratus is a climbing annual plant that attaches itself with tendrils to anything it can find support on. Once established, the plant can reach a height of 180 to 250 cm, depending on the conditions and the support provided. A wire mesh trellis, climbing net, bamboo poles, or a trellis are ideal for guiding this vigorous climber upwards.

Location and care

'Mammoth Mixture' thrives in a sunny location. The more sun, the more flowers. The soil should be fertile, slightly moist, and well-drained. Standing water should be avoided, but the plant does appreciate regular watering, especially on hot summer days.

For best results, use Lathyrus odoratus seeds:

• Sow from March indoors or in a greenhouse, or

• Sow directly from April in the final location.

If necessary, soak the seeds in lukewarm water for 12–24 hours to speed up germination. When the young plants have a few leaves, you can lightly pinch off the tops to encourage them to branch out and produce more flowers.

Regularly removing spent flowers (or harvesting cut flowers) prevents seed formation and significantly extends the flowering period.
