This entry keys on sweet Annie—an annual artemisia that smells like camphor candy and self-sows like it pays rent in seeds. Feathery leaves, tiny cream flowers, legendary medicinal chemistry that launched modern antimalarial research (not a DIY prescription—respect the plant and the pharmacology). In subtropical and tropical Americas it completes a fast cycle in warm seasons; humid summers can bring foliar funk without airflow. ☀️💧 Sun and Water Requirements: - Full sun for aromatic oils and sturdy stems. - Well-drained, average fertility; drought-tolerant once established—wet clay rots crowns. ✂️ Methods to Propagate: - Seeds: surface sow; tiny seeds need light and steady moisture. - Self-sows; thin volunteers unless you want a monoculture perfume riot. 🌾 Harvest notes: - Harvest leafy tops before full bloom for traditional drying—timing affects chemistry; use vetted guides.
