Common names
Lathyrus odoratus 'Bishop Rock'.
- Toxicity
To humans
The common name for Lathyrus odoratus 'Bishop Rock' is sweet pea. Although sweet peas are known for their beautiful flowers and pleasant scent, they contain toxic amino acids such as beta-aminopropionitrile, which can cause a condition known as lathyrism when consumed in large quantities. Lathyrism is characterized by symptoms that may include weakness and paralysis of the lower limbs, and in severe cases, could potentially affect the nervous system. Lathyrism is more commonly associated with the chronic ingestion of the seeds or seedlings over a long period rather than from casual or occasional contact with the plant.
To pets
Sweet pea, the common name for Lathyrus odoratus 'Bishop Rock', is also toxic to pets. As in humans, the toxicity is due to the presence of amino acids, such as beta-aminopropionitrile. If pets consume sweet pea seeds or seedlings, they may exhibit signs of lathyrism. Signs of sweet pea poisoning in pets can include lethargy, convulsions, and difficulty breathing. Chronic ingestion can lead to more severe symptoms including muscle tremors and seizures. Immediate veterinary attention is recommended if sweet pea ingestion is suspected in a pet.

- Water
Sweet peas, including the 'Bishop Rock' variety, prefer consistent moisture without becoming waterlogged. It's best to water these plants with about 1 inch of water per week, increasing to 2 inches in arid conditions or when temperatures are especially high. Early morning is an ideal time for watering, allowing the foliage to dry out during the day to prevent fungal diseases. When watering, aim for the base of the plant to minimize moisture on the leaves and provide a deep soaking, which encourages deep root growth. During rainy periods, reduce the watering frequency to avoid overwatering.
- Light
Sweet peas like the 'Bishop Rock' variety thrive in full sunlight, which means they require at least 6 to 8 hours of direct sun daily. Plant them in a spot where they get morning light, which is less intense than afternoon sun, especially in hot summer areas. If grown in too much shade, sweet peas will have fewer blooms and may become leggy.
- Temperature
Sweet peas, such as 'Bishop Rock', grow best in cool to moderate temperatures, with ideal conditions ranging between 55°F and 65°F. They can tolerate temperatures as low as 25°F for short periods, but prolonged exposure to heat above 75°F may hinder flowering and can lead to the plant's decline. It is important to plant them early enough in the season so they can flower before the heat of summer sets in.
- Pruning
Pruning sweet peas like 'Bishop Rock' encourages more blooms and prevents the plant from becoming leggy. Pinch out the tips of the seedlings once they reach about 4-6 inches in height to promote bushier growth. Deadhead regularly to stimulate new flowers. The best time to prune is during the cooler parts of the day, either early morning or late afternoon.
- Cleaning
Not needed
- Soil
Sweet Pea 'Bishop Rock' thrives in rich, well-draining soil with a pH between 6.0 and 7.5. A good mix would be two parts loam, one part well-decomposed compost, and a handful of perlite for drainage.
- Repotting
Sweet Peas are annuals and usually do not need to be repotted as they complete their life cycle within one year and can be sown directly into the ground or their permanent container.
- Humidity & Misting
Sweet Pea 'Bishop Rock' prefers moderate humidity levels but is generally adaptable to typical outdoor humidity conditions.
- Suitable locations
Indoor
Place in a sunny spot, ensure good airflow, and use a trellis.

- Life cycle
Sweet Pea 'Bishop Rock' begins its life cycle when seeds are sown, typically in late winter or early spring, and germinate in warm, moist soil conditions. Seedlings emerge, developing into climbing vines with tendrils that can reach up to 6 feet with support. The foliage matures, and distinctive, colorful, and fragrant flowers bloom from early summer to fall. Post-bloom, the plant sets seed pods that mature, eventually drying to release seeds if not removed for garden tidiness or seed saving. The plant will then go dormant, particularly in areas with frost, as it is an annual, completing its lifecycle within one year unless seeds are collected and sown again the next season.
- Propogation
Propogation time
Spring to early summer
Lathyrus odoratus 'Bishop Rock', commonly known as sweet pea, is a popular ornamental plant renowned for its fragrant flowers and is typically propagated by seed. The best time to sow sweet pea seeds is either in late fall or from late winter to early spring, depending on the local climate. The most popular method involves soaking the seeds in water for 24 hours to soften the seed coat, enhancing germination rates. After soaking, the seeds are sown in pots filled with well-draining soil, about 1 inch deep (approximately 2.5 cm), and spaced around 2 inches (approximately 5 cm) apart. The pots are then kept moist and in a cool, bright location until germination, which usually occurs within 10 to 14 days. Once the seedlings have developed several true leaves, they can be transplanted to their final growing positions, ensuring they have support for climbing as they grow.
