The story
Sage was the healing herb of the Romans and the Salerno medical school, which asked why a man should die who grew it; it stuffed geese in medieval England and Thanksgiving turkeys ever after. It is a Mediterranean shrub that wants dry feet.
Planting
Full sun and lean, drained soil; plant in spring, 2 feet apart. It is hardier than most Mediterranean herbs.
Growing
Water rarely and prune hard in spring, after the new growth starts, to keep it from going woody. Replace after five years.
Harvest and use
Pick leaves any time; harvest before flowering to dry. The blue flowers are edible.
What to watch for
Root rot in wet soil; winter kill in the coldest zones.
Safety
Sage contains thujone. Cooking amounts are fine, but avoid large medicinal doses and sage oil, especially in pregnancy or with seizure disorders.
Medicinal uses here are shared as history, not advice. Kitchen amounts are fine for most people, but teas, tinctures and supplements can interact with medicines and aren't safe for everyone, especially in pregnancy, while breastfeeding, for children, or with liver or kidney problems. Ask a doctor or pharmacist before taking any plant as medicine.
