Care
Light exposure
Scurvy grass prefers full sun to partial shade. It tolerates windy locations well, typical of coastal areas where it grows naturally. Good light promotes vigour and foliage density.
Soil and drainage
This plant appreciates well-drained, slightly moist soil and preferably alkaline or neutral. It tolerates poor and rocky soils. Excellent drainage is essential to prevent root rot in winter.
Watering
Keep the soil regularly moist during growth, particularly in spring and summer. Reduce watering in winter when the plant enters dormancy. Avoid waterlogging, which promotes rot.
Pruning and harvesting
Prune lightly after flowering to maintain a compact shape and encourage a bushy habit. Leaves and young shoots can be harvested regularly for consumption as needed.
Fertilising
A balanced fertiliser application in spring is sufficient for poor soils. Scurvy grass is not very demanding and prefers moderately fertilised soils. Excess nitrogen promotes foliage at the expense of robustness.
Diseases and pests
Like all brassicas, it can be affected by white rust and flea beetles. Ensure good air circulation and avoid stagnant moisture. Regular harvesting of foliage contributes to overall vigour.
Did you know?
Scurvy grass was once called 'scurvy herb' because sailors took it on long voyages to prevent this disease caused by vitamin C deficiency. Its scientific name 'officinalis' recalls that it featured in traditional pharmacopeias, used both as a medicinal plant and as a condiment for its peppery and slightly bitter leaves.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
