Citrus limon
Medium · Some experienceAbout Lemon
Citrus limon, the lemon tree, is a beloved fruit tree that thrives as a compact container plant, producing fragrant white flowers and bright yellow fruit year-round in the right conditions. Native to northeastern India and Myanmar, lemons spread through the Arab world to the Mediterranean by the 1st century AD. Indoor lemon trees need maximum light — a sunny south-facing window is essential. The intensely fragrant blossoms can perfume an entire room. Dwarf varieties like 'Meyer' and 'Improved Dwarf' stay under 2 meters in containers while still producing abundant fruit.

History
Citrus limon is not a wild species but a hybrid of the citron (C. medica) and the bitter orange (C. × aurantium), thought to have originated between northeast India, northern Burma, and southwestern China roughly 2500 years ago. It reached the Mediterranean via Arab traders in the early medieval period, and by the 12th century was in widespread cultivation in Sicily and Andalusia. Its most consequential medical role came in 1747, when Scottish naval surgeon James Lind demonstrated in a famous clinical trial that lemon juice prevented scurvy — a discovery that ultimately led to daily lime/lemon rations aboard Royal Navy ships and to the American slang 'limey' for British sailors.
Today it is grown commercially across the Mediterranean, California, Argentina, and Mexico. Lemons traveled one of the longest trade routes of any fruit — from Assam, India through Persia, to Arabia, then to the Roman Empire, and finally to the Americas with Columbus in 1493.
The Meyer lemon, a lemon-orange hybrid discovered in Beijing by USDA explorer Frank Meyer in 1908, revolutionized indoor citrus growing due to its compact size and sweeter fruit. Fruit is safe to eat; essential oils from peel and leaves are mildly toxic to pets.
