Pseudofumaria alba: complete guide

Overview

Pseudofumaria alba, the pale corydalis, is a delicate alpine groundcover producing airy white flowers. This compact spreading plant grows widely across European mountain ranges. The refined flower structure and finely dissected foliage make this a rock garden favorite.

Appearance and Bloom

The plant reaches only 20-30 cm tall with finely divided, ferny foliage. Flowers appear May through August in loose racemes. Pure white flowers display subtle yellow tones at the spur base. Each flower is elegant and refined.

Ideal Location

Position in dappled shade with afternoon protection in warm regions. The plant thrives on protected mountain slopes. Moist corners with excellent drainage are ideal. Avoid harsh midday sun in lowlands.

Soil Requirements

Extremely good drainage is absolutely essential. Create mixture of gravel, sand, and humus-rich compost. Neutral to slightly alkaline soil (pH 7.5-8) is preferred. Ensure perfect drainage to prevent root problems.

Watering

Constant moisture is preferred but never waterlogged. Water regularly during the growing season. Winter moisture can diminish to minimal levels. Grit mulch helps maintain moisture balance.

Pruning

Minimal pruning is necessary. Deadhead spent flowers to extend bloom period. Clear dead foliage in autumn. Remove damaged material immediately.

Maintenance Calendar

Spring: Resume growth; apply balanced fertilizer. Summer: Regular watering; deadhead flowers continuously. Autumn: Prepare for dormancy. Winter: Dormant period with minimal attention.

Winter Hardiness

Fully hardy to -15 degrees Celsius. Snow cover provides natural protection. Ensure dryness during winter to prevent ice formation.

Companion Plants

Combine with other alpine flowers like saxifrage and Dianthus alpinus. Group three or five plants together. Underplant with silver foliage plants for contrast.
