Care
Watering
Scutellaria likes moist soil and shouldn't dry out. Water regularly during the growing season, especially in summer. It tolerates soils that naturally retain some moisture, particularly in boggy areas or near water features.
Exposure
Ideal in part shade to full sun. It flowers generously in sunlight, but tolerates part shade well, especially in very hot regions. Choose a location with afternoon sun protection if you're in a Mediterranean climate.
Soil
Prefer moist, organic-rich and well-drained soil. This plant particularly appreciates light soils that don't retain stagnant water. Amending with compost at planting time improves establishment.
Pruning
Perform light pruning after flowering to maintain a compact shape. In late winter, cut back dry stems to ground level. This pruning promotes dense branching and better flowering the following year.
Fertilizer
Moderate fertilization: a spring compost application is usually sufficient. In poor soil, apply balanced fertilizer in spring to support growth. Avoid excess nitrogen, which would promote foliage at the expense of flowering.
Diseases and pests
Generally a robust plant that's rarely affected by pests. Watch for powdery mildew in overly humid, confined conditions. Good drainage and adequate air circulation limit these risks. It's typically not affected by major pests.
Did you know?
Scutellaria owes its common name to the shape of its calyx, which resembles a small cap or hat. In traditional herbal medicine, particularly in Northern Asia, it was long used for its calming properties, though its modern use has remained limited.
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.
