Description
The Lathyrus latifolius 'Red Pearl', also known as Broad-leaved Vetch 'Red Pearl', is a carmine pink version of the broad-leaved vetch. This adorable little climbing herbaceous plant offers clusters of large papilionaceous flowers from June to September, in a very bright pink, almost red. The plant attaches itself to its support thanks to tendrils that suspend its matte green foliage and broad flattened stems, or crawls on the ground freely. It is a hardy and drought-resistant plant that enjoys sunlight and a well-drained, rather fertile soil.
Introduced before 1635, the perennial pea became popular in the 1900s; it was often cultivated on a floral cage, a very fashionable accessory in Victorian England. This vetch is a plant from the fabaceae family native to Chile, and grows well in sunny fallow land on rather limestone soil. With rapid growth, the stems develop tendrils that attach themselves to the support you have provided when planting. Growing from a large fleshy root, this plant easily reaches 1.80 m (6ft) in a few months. Flowering takes place from June/July to September, providing it does not lack water. Its papilionaceous flowers, 2 to 3 cm (1in) long, are grouped in axillary clusters of 10 to 15 flowers. It is an excellent cut flower. If it likes its environment, the perennial pea is so vigorous that it can become invasive by abundant self-seeding.
This charming plant has more than one asset: crisp bluish foliage, small clusters of tightly curled buds, and finally, the vivacity of its carmine pink flowers. It thrives in warm and sunny places as well as in well-drained or even rocky soils. It is a perfect plant to quickly dress up a brand new garden, a slightly wild area, sad branches of conifers or deflowered spring flowering bushes, including roses. Easy to grow, the large seeds of Lathyrus latifolius are easy to handle and can be easily sown by children. This perennial pea is perfect for embellishing a trellis, a fence, and even a pot on the terrace throughout the summer, by mixing pink, red, and white varieties. This pea is an aerial vagabond with a formidable base. If it settles in the garden, it multiplies and spreads at will, attacking other perennials without suffocating them under its light weight. In a bouquet, it remains beautiful for several days, with buds opening in white tinged with green, very refined and blending well with a few spikes of Buddleia that provide the missing fragrance.

Planting and care
Plant Lathyrus latifolius in full sun or light shade. Install the plant in ordinary soil, preferably limestone and well-drained, but it can live in any good garden soil. Regular watering without excess will accelerate its growth. A sunny location, a supply of fertiliser for flowering plants, and the removal of faded flowers will promote abundant flowering from June to September and limit seed formation. Beware of snails and slugs that love to devour young plants.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
