Lime (Citrus limonia) Rangpur Despite its name, this intriguing citrus is no Lime at all! This no lime, in fact, it is a hybrid of Lemon and Mandarin. This unusual plant produces bright orange fruits with the sour flavour of lemons, and rich, floral perfume. The leaves are aromatic, much like Kaffir Lime leaves, and can be used in the same way to flavour curries. The prolific fruits make a superb alternative to Lime, adding a tart, citrus tang to dishes. Boasting glossy foliage and sweetly scented flowers, the Rangpur Lime makes an attractive specimen plant for the conservatory.
