When Thomas Jefferson was serving as U.S. President, his mâitre d'hôtel, Étienne Lemaire, bought basil at the Washington market and it was cooked with venison.1 In a letter written in February 1820, Jefferson's neighbor, George Divers of Farmington, noted that he was not able to supply Jefferson with the pot-herbs "sweet marjoram. sweet basil. or summer savory."2
Ocimum was the Greek word for the aromatic herb called basil in English. Although native to tropical Asia, sweet basil has been cultivated for thousands of years throughout Europe with references in Britain as early as the 1400s.3 Basil was common in America by the late 1700s. Philadelphia nurseryman Bernard McMahon listed basil seed for sale on his 1810 broadsheet.
This is a tender annual herb with aromatic, edible foliage and white flowers in terminal spikes on the branches.
