Care of the climbing plant Lathyrus odoratus or Sweet pea

The genus Lathyrus belongs to the Fabaceae family and includes 160 species of herbaceous plants distributed over almost all continents. Some species are: Lathyrus odoratus, Lathyrus latifolius, Lathyrus clymenum, Lathyrus rotundifolius, Lathyrus vernus.

Common names: Sweet pea, Wild Pea, Vetchling. This species is native to Sicily and southern Italy.

They are fast-growing annual climbing herbaceous plants that reach 2 meters (6.56 feet) in height. The leaves are pinnate-compound, alternate and of an intense green color. The showy scented flowers form clusters and can be pink, white, red, or blue. They bloom in spring.

They are used in pots for balconies and terraces, to create patches of color on lawns and to cover low walls; they need supports to climb. They are ideal for Mediterranean coastal gardens. They are also used as cut flowers for floral decorations.

Lathyrus odoratus grows in full sun and semi-shade exposures. They do not resist frost.

The soil should be cool, light, well drained, and contain organic matter.

Water moderately throughout the year except in summer when they are watered frequently but without flooding.

During flowering, fertilize with mineral fertilizer every 15 days.

Prune faded flowers to promote flowering. After flowering the specimens are removed (grown as annuals).

They are sensitive plants to the attack of aphids, caterpillars, fungi and insects.

They are propagated from seeds sown in fall or spring directly in the final location. To speed up germination, immerse the seeds in warm water. Sow 25 cm (9.84") deep.
