Artemisia alba: complete guide

Overview

Artemisia alba, commonly known as White Wormwood or White Mugwort, is an aromatic herb native to the Mediterranean region. This elegant plant belongs to the Asteraceae family and grows naturally in Mediterranean areas from Spain to Romania. The silvery foliage and subtle fragrance make it a popular ornamental and culinary herb.

Appearance and Bloom

The plant reaches heights of 30-80 cm with finely branched, silvery-green foliage. The leaves are intricately divided with a characteristic camphoraceous scent. Small, discrete white to yellowish flowers appear in dense spikes from September through October. The plant structure is compact and rounded.

Ideal Location

White wormwood blooms optimally in full sun on dry terrain. The plant loves open, windy locations where air circulates freely. Protection from early morning frost is beneficial. The plant is highly self-sufficient and requires minimal care.

Soil

Requires well-draining, dry soil and does not prefer moisture. Ideal composition is sandy or gravelly mix with minimal organic matter. The plant tolerates poor soil and salt conditions. Soil pH may be neutral to slightly acidic.

Watering

The plant prefers dry conditions once established. Water only during extended droughts. Overwatering can lead to disease. Mulch should be kept limited around the plant.

Pruning

Regular pruning helps keep the plant compact and full. Prune in early spring back to 30 cm height. After flowering, remove flowers for neater appearance. Avoid allowing the plant to become overgrown without pruning.

Maintenance Calendar
