Lathyrus odoratus 'Mammoth Mix' (Sweet Pea)

Common name: Sweet Pea 'Mammoth Mix'

Description: Lathyrus odoratus 'Mammoth Mix' is a vigorous, tall-climbing sweet pea producing large, boldly coloured flowers in an impressive range including pinks, reds, whites, purples, and bicolours, with a strong, intensely sweet fragrance. The large flower size and long stems make it an outstanding variety for cutting, and regular picking encourages continuous flowering throughout summer. Plants climb vigorously by tendril and require support — canes, trellis, or a wigwam of sticks — but reward the effort with one of the most fragrant and prolific summer displays available in any cottage garden.

Other benefits: large blooms with outstanding fragrance; excellent for cutting; very long flowering season if regularly picked; vigorous climber

Wildlife attraction: bees, bumblebees, and butterflies

Height & spread (approx.) at maturity: 1.5–2m (climbing, with support)

Position: full sun; requires support — trellis, canes, or a wigwam; sheltered from strong winds

Soil pH: neutral (pH 6.5–7.5); fertile, deeply prepared, well-drained soil; benefits from added organic matter at the base

Moisture: regular, consistent watering essential once established; do not allow to dry out; feed with a balanced fertiliser through the season

Winter hardiness: half-hardy annual; sow under glass from late winter or direct outdoors in spring
