Lathyrus latifolius 'Pink Pearl' – An elegant, ever-flowering perennial sweet pea plant for the garden and patio

Lathyrus latifolius 'Pink Pearl', also known as the perennial sweet pea or perennial sweet pea, is an exceptionally charming and easy-care climber that transforms any garden into a romantic, colorful display. While annual sweet pea varieties are often known for their delightful fragrance but shorter lifespan, 'Pink Pearl' distinguishes itself with its perennial character, abundant blooms, and vigorous growth habit. This variety returns year after year and offers an abundance of soft, pearly pink flowers that are a real eye-catcher during the summer months.

A perennial climbing plant with long-lasting flowering

Lathyrus latifolius 'Pink Pearl' is known for its long flowering period, which typically runs from June to September. The delicate, butterfly-like flowers appear in large clusters and immediately attract attention with their subtle sheen and soft pink hue. Although this perennial variety has less fragrance than the classic annual sweet pea, it more than makes up for it with its strong, reliable blooms and hardiness. This makes 'Pink Pearl' ideal for gardeners looking for a low-maintenance yet graceful climber.

Growth habit & properties

This perennial sweet pea reaches a height of approximately 150 to 200 cm, depending on its location and support. It is a climbing plant, attaching itself with tendrils to trellises, pergolas, fences, or trellis. Thanks to its robust stems and lush foliage, it forms a dense canopy that is also ideal for camouflaging less attractive areas in the garden.

'Pink Pearl' is also very hardy (down to around -15°C) and emerges from the rhizome every spring. Once established, the plant is highly drought-resistant, making it ideal for both sunny borders and warmer locations.

Location & care

For optimal growth, plant Lathyrus latifolius 'Pink Pearl' in a sunny to partially shaded spot. The more hours of sun it receives, the more abundant the blooms. The plant thrives in well-drained, humus-rich soil. Regular watering during the growing season promotes vigorous growth and long-lasting blooms.

Provide the plant with a sturdy climbing support, especially in the first few years. An annual pruning in early spring keeps the plant in shape and encourages vigorous new growth. Remove spent flowers to prolong flowering and reduce seed formation.

Applications in the garden

Lathyrus latifolius 'Pink Pearl' is exceptionally versatile. It is ideal for:

• Climbing frames, pergolas and fences

• Cottage gardens and romantic garden styles

• Natural borders with a loose, lush appearance

• Cut flowers for bouquets (although this variety has a less strong scent)

The soft pink hue combines beautifully with blue, purple, and white flowers. Think lavender, salvia, campanula, or clematis. This perennial climber also thrives in a wild or organic garden, where it can form a dense, natural growth.
