Lore & Background
Basil is an annual or sometimes perennial herb with glossy, ovate leaves arranged oppositely along square stems. Leaves may be green or purple, and the plant produces small white flowers on a central spike. As typical for Lamiaceae, the stamens and pistil lie under the upper lip of the corolla. After pollination, four round achenes develop inside the calyx. The exact taxonomy of basil is uncertain due to numerous cultivars, polymorphy, and frequent cross-pollination, with at least 60 varieties of Ocimum basilicum. Hybrids include lemon basil (O. × africanum) and African blue basil (O. × kilimandscharicum).
Reader's Guide
Basil is significant as a widely cultivated culinary herb, with varieties such as sweet basil, Thai basil, and Genovese basil used fresh in cuisines worldwide. Its distinct scents come from volatile aromatic compounds that vary with cultivars; European basil essential oil contains high concentrations of linalool and methyl chavicol. Basil is sensitive to cold and grows best in hot, dry conditions with full sun and well-drained soil. It can be propagated by seeds or cuttings, with blue light accelerating root formation in cuttings. Basil's name derives from Latin and Greek words meaning 'royal/kingly plant,' and it has been confused with the basilisk, as it was thought to be an antidote to the basilisk's venom.
