Description

The pecan tree is a large tree from 20 to 25 meters in height on average, but it can reach up to 40 meters in height and 6 meters of circumference (1 m from height).

The Feuille S made up imparipennées, long from 35 to 60 cm have from 11 to 13 pairs of Foliole S. the Pétiole is Pubescent.

The Fruit of oblong cylindrical form is a Drupe, déhiscente until the base. The external Pericarp, the Husks, measurement from 2 to 3 mm thickness.

The dry fruit, or Pacane, which is in fact the core of the drupe, is of variable form, generally ovoid, more or less lengthened. It is smooth outside and of brown color. It measures from 3 to 4 cm length on 2 cm in diameter. The almond bilobate and is surrounded by a red film clearly, the endoplèvre. Its taste resembles that of the Noix.

Distribution

This species is originating in the part is the United States: of south of the States of the Illinois and of Iowa, the Kansas, the Missouri, the Oklahoma, and Texas until in Virginia. It was naturalized in the remainder of the North America.

Introduced in Europe at the 19th century, the pecan tree was hardly spread because, although resisting cold winter European, it needs strong heats in summer so that its nuts mature. He can thus push everywhere in France but will not bear fruit everywhere (except if one uses varieties originating in the North of the United States).

Culture

Its culture is important with the the United States where hundreds of varieties are counted. The great producing States of the pecan nut are the Texas, the Georgia, the Alabama, the Louisiana and the Oklahoma.

The pecan tree appreciates the climates where it is cold during the winter and very heat the summer (Zone USDA 5-9). The varieties resulting from the north of the surface of natural distribution are satisfied with summer shorter and more expenses.

Others

In 1906, the governor of Texas, James Stephen Hogg, made pecan tree the tree symbol of Texas.
