description
Carob is a flowering evergreen shrub or tree in the pea family, Fabaceae.
Carob trees grow up to 15 meters (49 ft) tall. The crown is broad and
semi-spherical, supported by a thick trunk with brown rough bark and sturdy
branches. Leaves are 10 to 20 centimeters (3.9 to 7.9 in) long, alternate,
pinnate, and may or may not have a terminal leaflet. It is frost-tolerant.
Most Carob trees are dioecious. The trees blossom in autumn. The flowers are
small and numerous, spirally arranged along the inflorescence axis in
catkin-like racemes borne on spurs from old wood and even on the trunk
(cauliflory); they are pollinated by both wind and insects. Male flowers
produce a characteristic odor, resembling semen.
The fruit is a pod that
can be elongated, compressed, straight or curved, and thickened at the
sutures. The pods take a full year to develop and ripen. The ripe pods
eventually fall to the ground and are eaten by various mammals, thereby
dispersing the seed.
common names & nomenclature
The word Carat, a unit of purity for gold alloys, was derived from the word
carob, alluding to an ancient practice of weighing gold and gemstones
against the seeds of the carob tree by people in the Middle East.
Ceratonia siliqua, the scientific name of the carob tree, derives from the Greek
kerátiοn, "fruit of the carob" (from keras "horn"), and Latin siliqua "pod,
carob". The dried pods taste like chocolate but are lower in sugar and lack
the enzyme theobromine.
