Citrus paradisi 'Rio Red' (Rio Red Grapefruit) is a highly productive and popular citrus variety prized for its large, seedless fruits with deep red flesh and sweet, mildly acidic flavour. This evergreen tree features glossy, dark green leaves and fragrant white flowers that develop into abundant, high-quality grapefruits. The fruits have a smooth, yellow rind that often blushes with pink and contain juicy, richly coloured flesh that is less bitter than traditional grapefruit varieties.
Ideal for home orchards, edible landscapes, and large containers, 'Rio Red' thrives in well-drained soil and full sun. It requires a warm, frost-free climate and benefits from regular watering during fruit development. This tree is self-fertile and typically begins bearing fruit within 2–3 years, providing both ornamental beauty and delicious harvests.
