How to Grow Lathyrus splendens
Overview
Lathyrus splendens, also known as pride of California or Campo pea, is a stunning climbing perennial vine native to Baja California and parts of San Diego County. With its showy red flowers and climbing habit, this wild pea plant makes an eye-catching addition to any garden.
Growing Conditions
Lathyrus splendens thrives in full sun to partial shade and well-drained soil. It is drought-tolerant once established but prefers regular watering during the growing season. This chaparral-loving plant adapts well to Mediterranean climates with dry summers and wet winters.
Planting & Care
Plant Lathyrus splendens seeds directly in the ground after the last frost in spring. The seeds germinate best at temperatures between 60-70°F (15-21°C). Water the seedlings regularly, especially during dry spells, and provide support for the climbing vines. Prune any dead or damaged growth to maintain plant health.
Common Problems
This hardy vine is relatively pest-resistant but may suffer from powdery mildew in humid conditions. Ensure good air circulation around the plants to prevent this fungal disease. If infested, treat with organic fungicides like neem oil or milk-based sprays.
Harvest or Enjoy
Once mature, Lathyrus splendens produces attractive, bright red flowers that bloom from spring through summer. The showy inflorescences are a delightful sight in any garden. While the peas themselves are not commonly consumed due to their bitterness, you can enjoy the plant's ornamental value and encourage native pollinators to visit your garden.
