Santa Teresa lemons are native to the Sorrento Peninsula of Italy, along the Amalfi coast on the Mediterranean. The original tree was discovered sometime before 1955, when it was brought to the United States. This is the lemon variety that the Italians have been using to make their world-famous Limoncello drinks. Santa Teresa lemons are large with a round, elongated shape. The medium-thick rinds are bright yellow and have deep oil glands which makes the zest high in lemon oils. The pale-yellow flesh is very juicy and contains few seeds. They will do best in full sun with in enriched, well-drained soil.
