Sweet Pea Leamington
Sweet Pea 'Leamington' Seeds
Sweet Pea 'Leamington' is a famous 'Spencer' type variety known for producing large, deeply waved, frilly flowers that resemble crushed silk in a clear, rich lavender-lilac colour. Unlike many modern show varieties that prioritise size over fragrance, 'Leamington' retains a strong scent and produces exceptionally long, straight stems, often with four blooms per stem, making it ideal for cutting.
Because it holds its vibrant lavender colour without fading in the sun, it has remained a staple on the competition bench for decades. It is a vigorous climber, reaching heights of up to 2.4m, and holds the prestigious RHS Award of Garden Merit (AGM) for its consistent performance and superior flower quality.

🌿 Understanding the Plant
Lathyrus odoratus 'Leamington' is a Hardy Annual (H3). It is the gold standard for lavender Sweet Peas, combining the ruffled elegance of the Spencer group with a vigorous growth habit that makes it suitable for both the garden border and the exhibitor's bench.
A Scented Classic: While some modern hybrids sacrifice scent for larger blooms, 'Leamington' remains one of the most fragrant lavender varieties available. Its perfume is sweet and traditional, making it a "must-have" for a sensory-focused cottage garden.
RHS Excellence: This variety is a recipient of the RHS Award of Garden Merit, confirmation that it is robust, reliable, and perfectly adapted to the British climate. It consistently produces high-quality stems and flowers year after year.
🌱 Growing Guide
Sweet Peas are famously rewarding, but they are "hungry" plants that require a little preparation to reach their full potential.
How to Sow:
Autumn Sowing (Best): Sow in October or November in deep pots or root trainers to accommodate their long taproots. Overwinter in a cold frame for the strongest plants and earlier flowers. Spring Sowing: Sow indoors from January to March. Sow seeds 1cm deep in moist compost; keep cool (approx 15°C) as excessive heat can actually inhibit germination. Germination typically takes 10-21 days.
Where to Plant:
Plant out in late March or April once the soil is workable. They demand full sun and a sheltered spot with sturdy support—think bamboo wigwams, trellis, or netting. Dig in well-rotted manure or compost before planting to provide the nutrients they crave.
Ongoing Care:
The Pinch: When the plants reach 10cm, pinch out the top growing tip to encourage side-shoots. The Golden Rule: Harvest flowers every 2 days and remove all seed pods immediately. If the plant is allowed to set seed, it will stop producing flowers. Feed weekly with high-potash fertiliser (tomato feed) once buds appear.
