Bitter Orange (Citrus aurantium) is a beautifully fragrant evergreen citrus tree valued for its highly aromatic flowers, decorative bright orange fruit, and versatile culinary uses. Traditionally grown in Mediterranean and subtropical regions, this attractive tree produces glossy dark green foliage and masses of intensely scented white blossom in spring, filling patios and conservatories with citrus fragrance.
The distinctive fruit has a sharp, tangy flavour and is widely used in marmalades, preserves, liqueurs, marinades, and traditional recipes. Bitter Orange is also prized for its aromatic peel and essential oils, commonly used in perfumery and natural products. The fruit ripens to a vibrant orange colour, creating striking ornamental appeal against the evergreen foliage.
Suitable for containers or sheltered garden planting in milder climates, Citrus aurantium thrives in a sunny, protected position with fertile, free-draining soil. In cooler regions, it performs especially well in greenhouses, conservatories, or on sunny patios where it can be protected from severe frost.
