South Africa has officially claimed the title of the world’s largest exporter of citrus, cementing its place as a global powerhouse in the citrus industry. From juicy oranges and easy-peeling naartjies to tart lemons and fragrant limes, South African citrus is finding its way onto tables across Europe, Asia, the Middle East and beyond.
The country’s favourable climate, diverse growing regions and long citrus season have helped make citrus one of South Africa’s most successful agricultural exports. But while most of us can easily spot an orange or lemon in the supermarket, the citrus family is far more varied than many realise.
Here’s a closer look at some of the most common citrus fruits, including how they differ in appearance, flavour and nutritional value.
Mandarins, naartjies and clementines
The mandarin family is one of South Africa’s fastest-growing citrus categories, particularly in export markets where seedless, easy-peeling fruit is in high demand.

Which citrus fruit contains the most vitamin C?
While most citrus fruits are excellent sources of vitamin C, oranges, lemons and mandarins are among the top performers. Grapefruit provides the added benefit of vitamin A, while blood oranges contain extra antioxidant compounds that contribute to their distinctive colour.
The healthiest approach is to enjoy a variety of citrus fruits throughout the season, allowing you to benefit from each fruit’s unique nutrient profile.
