Ceratonia siliqua
Also called Carob Tree, St. John's Bread, Locust Bean, Carob Bean, Carob Tree Bean, Locust Tree, St John's Bread
Carob is an evergreen tree or shrub of the legume family, grown for its edible seed pods and as a drought-tolerant ornamental in warm, dry climates. It is best planted in full sun with well-drained soil and little summer water once established.
The carob ( KARR-əb; Ceratonia siliqua) is a flowering evergreen tree or shrub in the Caesalpinioideae subfamily of the legume family, Fabaceae. The carob tree is native to the Mediterranean region and the Middle East. It is widely cultivated for its edible fruit, which takes the form of seed pods, and as an ornamental tree in gardens and landscapes. Spain is its largest producer, followed by Italy and Morocco.
Carob pods have a number of culinary applications, including a powder or chips that can be used as a chocolate alternative. The seeds are used to produce locust bean gum or carob gum, a common thickening agent used in food processing.
The vegetative propagation of carob is naturally restricted due to its low adventitious rooting potential. Therefore, grafting and air-layering may prove to be more effective methods of asexual propagation. Seeds are commonly used as the propagation medium. The sowing occurs in pot nurseries in early spring and the cooling- and drying-sensitive seedlings are then transplanted to the field in the next year after the last frost. Carob trees enter slowly into production phase. Where in areas with favorable growing conditions, the cropping starts 3–4 years after budding, with the nonbearing period requiring up to 8 years in regions with marginal soils. Full bearing of the trees occurs mostly at a tree-age of 20–25 years when the yield stabilizes. The orchards are traditionally planted in low densities of 25–45 trees per hectare (10 to 20/acre). Hermaphroditic or male trees, which produce fewer or no pods, respectively, are usually planted in lower densities in the orchards as pollenizers.
Intercropping with other tree species is widely spread.
The carob tree is native to the Mediterranean region and the Middle East. Although cultivated extensively, carob can still be found growing wild in eastern Mediterranean regions, and has become naturalized in the western Mediterranean.
