Glen Citrange
Glen citrange (Citrus sinensis × Poncirus) is one of the historic citranges of the American USDA program, a hybrid of sweet orange and Poncirus trifoliata. Its tree hardiness reaches 10°F (−12°C), making it suitable for in-ground growing in USDA zone 8a. The vigorous tree reaches 10 to 16 ft (3 to 5 m) with an upright, semi-thorny habit, semi-evergreen trifoliate foliage inherited from Poncirus, and white spring flowers. Its yellow-orange fruit, medium-sized at 3.5 to 7 oz (100 to 200 g) and thick-skinned, ripens in winter and yields a markedly sour juice with a sweet-orange fragrance, acceptable for juice, marmalade, or as a cocktail base. A few seeds. Glen belongs to the lineage of citranges used both as a supplementary citrus and as a rootstock in regions with continental winters. Graft onto pure Poncirus trifoliata.
Yuzu N3
Yuzu N3 (Citrus junos ‘N3’) is a vigorous seasoning citrus, sought after for its floral zest and very fragrant juice. To prepare for growing it, cautiously adopt a benchmark close to 5°F (−15°C) on a mature, well-established tree subjected to a brief frost, rather than a guarantee of survival at a precise temperature. The tree generally reaches 10 to 13 ft (3 to 4 m). Its very sour fruit, rich in seeds and relatively low in juice, are harvested from October to December and are used mainly for the zest, the juice, and preserves.

Eremorange
Eremorange (Citrus glauca × Citrus sinensis) is a remarkable hybrid between the Australian desert lime (Eremocitrus glauca) and the sweet orange, created in Australia to combine cold hardiness and drought tolerance. Its exceptional hardiness reaches 5°F (−15°C) on the tree, classed in USDA zone 8a by Biggio and Londeix as well as G. Roques; Mon Jardin Extraordinaire offers its selection grafted onto FA5 in zone 7, which remains to be verified for the clone grown. The tree reaches 7 to 13 ft (2 to 4 m) with a spreading habit, almost exotic silvery foliage evoking an olive tree, and fragrant white flowers. Its small, light orange fruit, with thin skin, ripen in fall and winter with juicy flesh and an original, slightly tart taste, blending orange and the lemony notes of the desert parent. Excellent in blended juice or in cooking for its unique notes. Very ornamental, particularly well suited to Mediterranean-continental gardens. Graft onto Poncirus trifoliata, perfectly drained soil, tolerates summer drought exceptionally well.
Yuko Lemon
Yuko lemon (Citrus yuko) is a rare Japanese citrus, sometimes called yellow yuzu, native to Japan where it has been grown for several centuries in coastal regions. Its hardiness reaches 14°F (−10°C) on the tree, with a USDA 8b climate benchmark used in this entry, indicative and to be confirmed for the material grown. The tree reaches 7 to 13 ft (2 to 4 m) with an upright habit, aromatic evergreen foliage, and fragrant white flowers. Its golden-yellow fruit, round to slightly flattened, with bumpy, thick skin, ripen in fall and concentrate a very fragrant sour juice evoking yuzu and lemon, with unique floral and resinous notes. Widely used in traditional Japanese cooking, in juice, zest, ponzu vinegar, and in niche pastry. A few seeds. Graft onto Poncirus trifoliata for hardiness, plant against a south wall. A rare collector’s citrus, little distributed in French garden centers.
Thomasville Citrangequat
Thomasville citrangequat (Citrus × georgiana) is an exceptional triple hybrid combining kumquat, orange, and Poncirus trifoliata, selected in Georgia in the United States. Its hardiness reaches 7°F (−14°C) on the tree, making it suitable for in-ground growing in USDA zones 7b and 8a, among the hardiest citrus. The tree generally reaches 7 to 10 ft (2 to 3 m), sometimes up to 13 ft (4 m) depending on catalogs and training, with a rounded thorny habit, semi-evergreen foliage, and fragrant white flowers. Its small golden-orange fruit, 1.6 to 2 in (4 to 5 cm), with thin skin, ripen in fall and winter and concentrate a very fragrant sour juice with intense zest, excellent candied, in liqueur, or in marmalade. Its skin is edible like that of kumquats. The tree is very ornamental and suits in-ground growing as well as a large container on a terrace. Graft onto Poncirus trifoliata to maximize hardiness.
Meyer Lemon
Meyer lemon (Citrus × meyeri) is a natural hybrid between the lemon and the mandarin or orange, native to China and introduced to the United States in 1908 by the botanist Frank Meyer. Its hardiness reaches 19°F (−7°C) on the tree, higher than that of the standard lemon, 25°F (−4°C), making it suitable for in-ground growing in USDA zones 8b and 9a. The compact tree reaches 7 to 10 ft (2 to 3 m) with a rounded habit, glossy evergreen foliage, and very fragrant white-mauve flowers, almost continuous. Its round yellow-orange fruit, with thin, smooth skin, ripen mostly in winter, with intermittent harvests all year depending on conditions, and have a juice that is less acidic than the standard lemon, fragrant and slightly sweet, ideal in pastry, lemonades, sauces, and Asian cooking. Fruit hardiness, 27°F (−3°C), remains limited: harvest before the first severe frost. Graft onto Poncirus trifoliata for in-ground growing, or grow in a container for colder zones.
