Citrus × aurantiifolia – Green LimeCitrus aurantiifolia, often grown as Green Lime or Mexican lime, is a compact evergreen citrus with aromatic leaves, fragrant white flowers and small rounded limes that ripen from green toward yellow. Its fine branching and small fruit make it well suited to pot culture in warm, high light conditions. Use a loose citrus substrate, water thoroughly after slight surface drying and keep it bright, sheltered and above about 10C in winter.
