Safety

People: Garden pea is not considered toxic to people. The seeds, pods and young shoots are commonly eaten as a vegetable.
Children: Garden peas are an everyday food and are not toxic to children. Dry seeds can be a choking hazard for very young children, so keep them out of reach.
Contact allergens: Handling the foliage may cause mild skin irritation in sensitive individuals.
Airborne allergens: The pollen can trigger hay fever symptoms in some people during the peak bloom period.
Edibility: The seeds of many Lathyrus species contain toxins that cause lathyrism if consumed in large quantities.

Growing it

Propagation: seed
When to plant: spring
Overwintering: In colder climates, the plants will die back completely after the first frost. Remove the dead vines and compost them to keep the garden tidy.
In containers: They grow well in deep containers, provided you use a pot at least 30 centimeters deep for root development.

Seed Sowing

1. Soak seeds in water for 4 hours.
2. Plant seeds 2 centimeters deep in individual pots.
3. Keep in a cool, bright spot until germination.
4. Transplant outdoors after the risk of frost has passed.

Provide a sturdy trellis or netting early in the season to support their rapid upward growth.
