Kagzi lemons are smaller in size and often harvested while the skin is still green, which means they're often mistaken for limes. But Kagzi lemons are actually lemons and ripen into a gorgeous light yellow color (via Shrigram Organics). This lemon is incredibly popular in India, with an impressive number of websites that sell Kagzi lemons or provide information. According to Aranyaani Food Forest, Kagzi lemons are in high demand in India because of their nutritional and medicinal value, as well as being relatively low in price. The tree is also easy to care for with a high fruit yield. Kagzi lemon plants require full sun exposure and well-drained soil to thrive.
