Lathyrus Odoratus seeds Sweet pea

LATIN NAME: Lathyrus odoratus

COMMON NAME: Sweet Pea

The sweet pea twines its slender stems and the winged leaf stalks, with the scented, winged flowers in the loose clusters, and the whole plant climbs the supports with the ease. The vigorous, climbing, annual plant carries the pinnate leaves with the paired oval leaflets and the winged leaf stalks, and the loose racemes of the large, butterfly-shaped, frilled, highly scented, pink, purple, red, white or blue flowers through the summer, one of the fine, sweet-scented sights of the cottage garden, drawing the bees. The flowers have a very long record as the fine, sweet-scented cut flowers of the old gardens, and the plant is a fine, historic presence of the cottage garden. It is a plant of the open, sunny, deep, rich, moist, well-drained ground.

Scientific Research & Plant Biotechnology

The sweet pea is a historic subject of the plant science, and the scented flowers keep showing up in the work on the climbing annuals. The way the loose racemes of the large, butterfly-shaped, frilled, highly scented flowers form along the winged leaf stalks has been studied steadily, and it keeps appearing in the studies of the climbing annuals, the scented flowers and the members of the pea family. The winged leaf stalks and the twining habit have also made it a fine study plant, and the sweet pea is a regular subject of the work on the scented flowers of the warm world.

Ecological & Economic Value & Wide Applications

The sweet pea is a fine, sweet-scented plant of the cottage garden and the cut-flower patch. The loose racemes of the large, butterfly-shaped, frilled, highly scented, pink, purple, red, white or blue flowers open through the summer, one of the fine, sweet-scented sights of the cottage garden, drawing the bees, and the long stems come to the vases as the fine, sweet-scented cut flowers of the old gardens. It is one of the fine choices for the cottage garden, the trellis and the study collection, and it has been written up in the horticultural and the botanical papers for the scented flowers and the very long history. It is a fine, sweet-scented plant of the open, sunny, deep, rich, moist, well-drained garden.

Give the young plants the trellis and the deep, rich, moist bed, and the scented flowers will open through the summer.

To grow the sweet pea from seed, sow the large, round seeds a couple of centimetres down in the deep pot of fine, gritty soil, keep the pot in a bright, open spot and water gently, then set the young plants out by the supports. The seedlings are up within a couple of weeks and grow on fast. With the sun, the trellis and the deep, rich, moist, well-drained ground, the scented flowers will open through the summer.

 

 

 

 

SYNONYMS: Lathyrus sativus odoratus

LATIN NAME: Lathyrus odoratus

COMMON NAMES: Sweet Pea, Garden Sweet Pea, Fragrant Pea Vine

Lathyrus odoratus is a charming cool‑season climbing annual originating from Mediterranean regions. Twining flexible stems use delicate tendrils to climb trellises, fences and supporting frameworks. Soft blue‑green compound leaves pair with abundant ruffled flower clusters that carry exceptional sweet fragrance. Blooms appear in varied shades of purple, pink, white and deep red. This beloved ornamental vine fits cottage garden borders, archway plantings and cut‑flower production plots. Seed‑sown stock provides a straightforward path to establish vigorous flowering vines for seasonal garden displays.
Starting sweet pea from seed delivers clear practical benefits. Seed‑grown specimens develop extensive fibrous root networks that thrive in rich garden loam. Early sowing extends the total flowering window throughout spring. Natural variation within seed lots brings gentle shifts in bloom colour intensity and scent strength among young plant groups.
Seed pods swell and turn dry papery brown once flowering finishes. Collect pods before they naturally split open. Shell out round dark seeds and separate them from dry pod husks and plant debris. A short warm‑water soak softens the hard outer seed coat and supports smooth moisture uptake. Cold stratification is not required for this annual. Fresh harvested seed maintains excellent planting vigour.
Place prepared seeds into deep, humus‑filled, freely draining growing medium. Cover seeds with a substantial layer of fine soil, as sweet pea seeds favour darkness for active growth. Bright dappled light protects tender new shoots from harsh mid‑day heat. Keep substrate consistently moist, avoiding water‑saturated compost. Under mild cool growing conditions, energetic seedlings emerge above soil.
Young seedlings produce characteristic paired leaflets and quickly form grasping tendrils. Thoughtful thinning removes overcrowded individuals and gives roots room to spread. Seedlings transplant gently while still small before root systems become tangled. Once outdoor frost danger passes, hardened plants settle beside trellises and supports. These seed‑raised vines climb upward rapidly, producing wave after wave of heavily scented colourful blossoms across spring months. Left on the plant, maturing seed pods allow welcome self‑sowing, returning new sweet pea seedlings to suitable garden spaces in the following growing year.

Sweet peas have been cultivated since the 17th century and a vast number of cultivars, such as Spencer Giant (usually mixed colours), are commercially available. They are often grown by gardeners for their bright colours and the sweet fragrance that gives them their name.
