An ornamental citrus tree prized for its fragrant white blooms and sharp tasting lemons amongst its glossy, oval leaves, born on stems that carry stout spines. Best grown in a container to limit its bushy growth, Citrus trifoliata will enjoy a conservatory setting during the winter (protecting it from temperatures below 10°C), and an outdoor sunny spot over summer. Highly scented white blossoms appear in spring and early summer, followed by 4cm (2in) wide fruits. Sometimes a second burst of lemon-scented blooms occurs in autumn.

Ideally grow in a pot which is easily moved from terrace to conservatory, in a specialist citrus-specific compost. Feed every two weeks with a special citrus fertiliser (there is one for summer and another for winter), and pot on or top-dress plants in late winter. Move outside after the risk of frost has passed to a sunny, sheltered patio. Minimal pruning required. Prune wayward or crossing branches to maintain a healthy framework.
