Caffin Clementine

Origin

The Caffin Clementine is an old variety discovered in 1968 at Azemour de Caffin, Morocco, as a spontaneous mutation on an existing clementine tree, then selected and stabilized for its exceptional earliness and the remarkable quality of its fruits. Quickly propagated around the Mediterranean basin, it became one of the few varieties allowed in the specifications of the prestigious Protected Geographical Indication (PGI) "Clémentine de Corse", which covers only clementine trees grown to strict criteria in Corsican orchards. This official recognition makes it one of the most legitimately representative varieties of French Mediterranean citrus know-how. The Caffin stands out for its particularly early maturity (from late September), its high productivity, the near-total absence of seeds, and its improved hardiness when grafted onto Poncirus trifoliata. Sold by several specialized French nurseries including Agrumerie Vessière, Pépinières Ripaud, and Terre Lointaine, it is a leading choice for anyone wishing to grow an authentic Corsican PGI clementine in their garden.

Tree description

The tree forms a handsome shrub of 8 to 10 ft (2.5 to 3 m) at maturity, with a rounded habit and evergreen foliage of a rich green. Growth is moderate, and the tree is very productive from the fourth year on Poncirus trifoliata rootstock. The choice of rootstock is decisive here, bringing hardiness to 16°F (−9°C), even 14°F (−10°C) depending on the site, versus only 19°F (−7°C) on standard FA5. The fragrant white spring blossom is abundant. Suited to zone 8b in acidic or non-calcareous soil (a Poncirus requirement).

Fruit quality

The fruits, medium to large (about 3 oz, or 80 g), have thin, bright orange skin that comes away easily. The flesh is firm, juicy, deep orange, almost entirely free of seeds, with a slightly tart, finely sweet flavor reminiscent of traditional Corsican clementines. Harvest begins in late September, when the skin is orange and the underside of the fruit keeps a greenish tinge, a sign of optimal freshness.

Flavor and ornamental interest

Eaten fresh, the Caffin Clementine offers one of the most authentically Corsican taste experiences possible: tart, sweet, and finely fragrant, it immediately evokes the orchards of the eastern plain. Its flesh lends itself to juices, fruit salads, traditional pastries (citrus canistrelli), and artisanal liqueurs. As an ornamental, the compact, productive tree suits a Mediterranean or Atlantic garden perfectly, its orange fruits persisting from September into early winter and providing prolonged landscape interest.
