How to Grow Yellow Corydalis
Pseudofumaria lutea
Yellow Corydalis thrives in partial shade in well-drained soil, including dry alkaline spots and wall crevices where little else will grow. Plant in spring or autumn and let it self-seed into gaps — it will find its own ideal spots. Water in during dry spells but established plants are drought-tolerant. Deadhead spent stems to extend the exceptionally long flowering season from spring through autumn. No regular pruning or feeding required; a light slow-release fertiliser in spring is ample.
Yearly Lifecycle
Care Essentials
Little feeding needed. A light dressing of balanced slow-release fertiliser in early spring is sufficient. Over-feeding encourages lush growth at the expense of flowers.
Watch For
- Slugs and snails on young growth
- Downy mildew in poorly ventilated spots
Companions
Ferns, Hostas, Hellebores, Epimedium, Aquilegia
Care Requirements
Light
Partial shade to full shade; tolerates sun if soil stays moist
Performs best in partial shade, such as north-facing walls and shaded borders. Tolerates full shade but flowers less freely. Can take morning sun in cooler climates if the soil does not dry out.
Watering
Low to moderate; drought-tolerant once established
Water in newly planted specimens and during prolonged dry spells. Once established, Yellow Corydalis is remarkably drought-tolerant and self-sufficient, particularly in shaded positions. Avoid waterlogging.
Fertilizing
Rarely needed; light slow-release feed in spring
Thrives in poor to moderately fertile soil. A light dressing of balanced slow-release fertiliser in early spring is sufficient. Avoid high-nitrogen feeds which reduce flowering.
Pruning
Deadhead to extend flowering; tidy foliage in late winter
Remove spent flower stems regularly to prolong the long flowering season and reduce self-seeding. Cut back any tatty semi-evergreen foliage in late winter before new growth emerges in spring.
