Wormwood (*Artemisia absinthium*) is a hardy, woody-based perennial known for its finely divided, aromatic silver-gray foliage. The plant typically grows to a height of 0.6 to 1.2 meters (2 to 4 feet) and spreads about 0.6 meters (2 feet) wide. Its small, yellowish, tubular flowers appear in dense, leafy, drooping panicles at the stem tips during summer, though they are considered insignificant compared to its striking foliage. The leaves are deeply lobed, covered with fine, silky hairs, and emit a strong sage-like scent when crushed. Wormwood thrives in well-drained soils and is drought-tolerant once established. 🌞💧 **Sun and Water Requirements:** Prefers full sun exposure for optimal growth but can tolerate partial shade. Requires well-drained soils and is drought-tolerant once established. Overwatering or poor drainage can lead to root rot. ✂️🫘 **Methods to Propagate:** Propagation is commonly achieved through seed sowing in spring or by division of established clumps in early spring or fall. Semi-hardwood cuttings can also be taken in late summer. 🧑‍🌾👩‍🌾 **When to Harvest:** Harvest the aerial parts during the flowering period in summer when the concentration of active compounds is highest. Dry the harvested material in a well-ventilated area away from direct sunlight.
