Lemon (Citrus limon) is a compact, thorny evergreen citrus tree valued for its tangy, juicy fruit and intensely fragrant white blossoms. Ever-bearing in warm Indian conditions, it can flower and fruit through much of the year, supplying kitchen-fresh lemons for cooking, drinks and home remedies. Its neat size makes it ideal for pots, terraces and small gardens, while the glossy leaves and perfumed flowers add ornamental charm. Lemon is relatively easy to grow given sun, good drainage and regular feeding. Few plants offer such a steady, useful harvest from so little space.
