Lathyrus venetus: complete guide

Lathyrus venetus, commonly known as Venetian Pea or Gesse de Venetie, is a charming wildflower native to Mediterranean and central European regions. This plant belongs to the Fabaceae family, the same family as peas and beans. It is native to Italy, Greece, and adjacent countries.

Overview

Lathyrus venetus is a small to medium plant typically reaching 20 to 60 centimeters in height. The plant grows as a climbing or scrambling plant with tendrils that attach to surrounding vegetation. What makes this plant truly special are its vibrant purple flowers appearing from May to June.

This plant is valuable for wild gardens and naturalistic garden schemes. The flowers attract butterflies and other pollinators, making it an ecologically valuable plant. Unlike many other cultivars, this is a true wild species without intensive cultivation requirements.

Appearance and blooming

The leaves of Lathyrus venetus consist of four to twelve small leaflets arranged along stems with tendrils. The leaves are green and fine in texture. The plant has a naturally climbing habit and does not form dense walls of vegetation.

Flowers appear from May to June and are deep purple to magenta in color. Each flower is approximately 12 to 15 millimeters long and grouped in loosely arranged racemes. These flowers are extremely attractive to butterflies and other pollinators.

Following blooming, elongated seed pods form. The pods are green and persist on the plant for considerable time. Seeds can be collected and stored for subsequent years.

Ideal location

Lathyrus venetus thrives best in sunny to lightly shaded locations. The plant appreciates at least 4 hours of direct sunlight daily. In warm climates, light shade can be beneficial.

The plant climbs along support structures, so place it where it can climb against structures or other plants. This creates a more natural appearance.

Soil requirements

Lathyrus venetus feels best in well-draining soil with pH between 5.5 and 6.5. The plant tolerates various soil types but thrives in moderately fertile soil. Add organic matter when planting.

The plant is not fussy about soil conditions and can even grow in relatively poor soils. This makes it valuable for less maintenance-intensive gardens.

Watering

During the growing season, Lathyrus venetus needs regular water. Water thoroughly when the top layer of soil feels dry. Ensure the plant does not dry out, especially during the flowering period.

In dry conditions, daily watering may be necessary. Once established, the plant can tolerate some drought, especially if it has developed deep roots.

Pruning

Lathyrus venetus can be trimmed back to shape and limit growth. The best time for pruning is after blooming in June. This also encourages side shoot formation and can produce a more compact plant.

Deadheading faded flowers also helps extend the flowering period and prevents excessive seed production.

Maintenance calendar

Spring (March-May): Plant from seed. Water regularly. Provide climbing support.

Summer (June-August): Enjoy the blooms. Water regularly. Prune after flowering.

Autumn (September-October): Seed can be collected. Allow some flowers to form seed for next season.

Winter (November-February): In mild climates, the plant may remain evergreen. In colder climates, it dies back and returns from seed.

Winter hardiness

Lathyrus venetus is hardy for temperate climates and tolerates temperatures down to approximately -10 degrees Celsius. In very cold climates, it may die in winter and regrow from seed. In warm climates, it can grow almost year-round.

Companion plants

Lathyrus venetus grows well alongside other wildflowers and pollinator-friendly species. Suitable companions include:

• Other vetchling species
• Daisies and lupines
• Cornflowers
• Delphiniums
