Pecan is a deciduous tree of the Walnut family. The native land of this plant is North America: the indigenous people of the continent for many centuries considered its fruits a key component of their diet. At present, this culture is widespread in the southeastern United States, in the Caucasus, in the Crimea, and in Central Asia.
Pecan is a fairly large woody plant, reaching a height of 55 meters. A powerful tree trunk covers the fissured bark of a grayish-brown color. Spreading large crown of the plant has a tapped, ovoid or spherical shape.
Pecan leaves look like ash trees. Complicate pinnate leaflets, reaching 50 cm in length, consist of 11-17 bright green elongate-lanceolate leaflets. Pecan is a monoecious plant: male (multi-colored drooping earrings) and female (sessile, collected from 3-11 pieces in glume inflorescences) flowers can simultaneously develop on one tree. In favorable conditions, flowering of representatives of this species continues from May to June.
Pecan fruits are elongated tetrahedral pseudo-pitted, reaching 27 mm in width and 83 mm in length. On top, each nut is covered with a fleshy, leathery pericarp, hardening and cracking during ripening. Under the skin there is a thin brown nutshell that hides an oily, light beige core beneath. Fruits ripen only by mid-autumn.
Pecans have excellent taste. The fruits of this culture are consumed in food fresh, dried and fried, used to prepare fruit or vegetable salads, pastries, confectionery and vegetable oil, vaguely reminiscent of the smell and taste of olive. Along with this, pecan nuts are used in traditional medicine.
