Care
Exposure
Favor a sunny to partially shaded exposure. This plant appreciates bright locations but also tolerates light shade. Avoid areas that are too dark, as they would reduce flowering.
Soil and planting
Cruciata glabra prefers well-drained, slightly chalky to neutral soils. Ordinary garden soil, even rocky or poor soil, suits it perfectly. Plant in spring or autumn in loose, uncompacted soil.
Watering
Water regularly during the growing period, especially during dry spells. Once established, this perennial is fairly tolerant of drought. In winter, reduce watering.
Pruning and maintenance
Cut back the clump in late winter or early spring, before growth resumes. You can also prune lightly after flowering to maintain a compact shape and encourage more abundant blooms.
Fertilizing
This plant is undemanding. A balanced fertilizer application in spring is generally sufficient. Prefer light feeding: excess nitrogen would favor foliage at the expense of flowers.
Diseases and pests
Cruciata glabra is generally little subject to diseases. Ensure good drainage to prevent waterlogging. With persistent excess water, watch for root rot.
Did you know?
The genus Cruciata owes its name to the characteristic arrangement of its leaves in a cross shape ("cruciata" means "cross-shaped"). Historically, several species in the genus were used in traditional European herbalism for their supposed soothing properties.
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.
