Overview
Citrus × paradisi is a vigorous evergreen citrus that originated in the Caribbean (Barbados) as a chance cross between the pomelo and the sweet orange. It produces large, segmented fruit on a dense, glossy-leaved tree.
Grapefruit trees are among the larger, more vigorous citrus, with dense glossy foliage, fragrant blossoms, and fruit that often clusters like grapes—the likely source of the name. They need long, warm seasons to ripen fully.
How to identify it
- Large, rounded, dense evergreen tree, 15-30+ ft, larger than most citrus
- Big, glossy, dark-green ovate leaves with broadly winged petioles
- Fragrant white four-petaled flowers
- Large round fruit, pale yellow to blushed pink, often hanging in grape-like clusters
- Segmented flesh ranging from white to pink to deep ruby-red
Care & growing
Light: Full sun (8+ hours).
Water: Water deeply, then let the topsoil dry; avoid waterlogging.
Soil: Well-drained, slightly acidic soil (pH 6.0-7.0).
Temperature: Frost-sensitive; best in zones 9-11. Needs long, hot summers to ripen fruit, which can hang on the tree for months.
Feeding: Regular citrus fertilizer with micronutrients; watch for nutrient-deficiency yellowing.
Propagation: Grafted onto rootstock for reliable fruiting and size control.
Habitat & origin
Grapefruit arose in Barbados in the 18th century and was later developed extensively in Florida and Texas, which became major producers.
Today it is grown across subtropical regions—the United States, China, Mexico, and South Africa. It needs a frost-free, hot climate to ripen its fruit fully.
