Care
Exposure
Carlina with acanthus-like leaves appreciates a sunny exposure to bloom abundantly. It tolerates partial shade but will be less generous. Install it in a warm, dry location, sheltered from strong winds that can damage its spiny leaves.
Soil
This plant requires well-draining, preferably chalky soil. It tolerates poor and stony soils much better than heavy, wet ones. If your soil is clayey, improve drainage by adding gravel or coarse sand.
Watering
Water moderately during the growing season, especially in the first year. Once established, as carlina tolerates drought well, you can space out waterings. In winter, minimize water: it fears excess winter moisture more than dryness.
Fertilizer
Undemanding, carlina requires only light feeding. A light spreading of mature compost in spring is ample. Avoid overly rich nitrogen applications that would favor foliage at the expense of flowering.
Pruning
No pruning is necessary. You can simply remove faded flowers to encourage prolonged blooming. In late autumn, cut dried stems down to ground level after the first frosts.
Diseases and pests
Very robust, carlina is rarely subject to disease when well established. Collar rot can occur in overly wet soil; ensure good drainage. No specific pests generally threaten it.
Did you know?
In the Middle Ages, carlina was renowned for its medicinal properties and considered a magical plant capable of warding off evil. Its large pale yellow flower heads, which persist long on the plant, led to its use dried as interior decoration, and people attributed to it the power to predict rain: its flowers would close before a storm.
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.
