Broad-leaved everlasting pea 'White Pearl'

Lathyrus latifolius 'White Pearl' | Also known as: Everlasting pea 'White Pearl', Hardy sweet pea 'White Pearl', Perennial pea 'White Pearl' | Rating: 0 votes | Print / Pdf

As a perennial climbing plant that sports pretty blossoms each summer, lathyrus latifolius is understandably a popular choice for gardeners with trellises, walls and fences to beautify. It is commonly known as the broad-leaved everlasting sweet pea, not just because of its broad, ovate grey-green leaves, but also due to its winged stems. A fast grower, its racemes of pink or light purple blossoms are what it is most admired for, with five heavily veined petals that are rippled, creating a look of delicate beauty. A lover of moist but well-drained soil, it thrives in full sun. It is a hardy plant, but pruning to the ground in autumn ensures better growth the next year.
