Citrus aurantiifolia (Key Lime)

Citrus aurantiifolia, commonly known as Key Lime, is a compact evergreen citrus tree prized for its aromatic leaves, fragrant white flowers, and small, tangy green fruits. This versatile tree is ideal for container growing, conservatories, or sheltered garden spots in the UK, adding a Mediterranean feel to outdoor spaces. It typically reaches an ultimate height of 2–4 metres when mature.

Thriving in well-drained soils, including loam, sand, and chalk, Citrus aurantiifolia flourishes in full sun and benefits from a warm, sheltered position. In the UK climate, it is best suited to greenhouse or patio growing, where it can be moved indoors during colder months. Regular feeding and pruning encourage healthy growth and an abundant fruit harvest.

This citrus tree is perfect for container planting, kitchen gardens, and ornamental use. Its highly fragrant flowers and zesty fruits make it an attractive and practical choice for homes and gardens.
