The leaves grow in groups of 11-17. Each leaf is slightly pointed at the tip. The width of the leaves are approximately 3 inches. Each full grown leaf is about 5 inches top to bottom. This tree is a perennial. The Pecan tree has a shallow root system. The flowers are tiny and hang down in tassels. The pecan uses wind to

pollinate. The pecan nut is long and pointed with a thin shell.

The pecan tree grows in North America. The tree is found in deciduous forests. Most pecan trees like humid climates. The tree is a member of the walnut family. The Pecan tree is the State tree of Texas. Pecan nuts were a major food source to the Native Americans. They would eat these nuts, and store them to survive through the winter. The tree is used for its wood to make furniture like cabinets, benches, stools, chairs, and other useful supplies.

The pecan industry produces 250,000,000 lbs. of pecans a year. Farmers harvest the nuts that have fallen off the tree. The nuts are not directly picked off the tree, because only the nuts on the ground are edible, and the ones on the trees are still growing. The nuts are put in boxes, and sold in stores and marketplaces. The pecan tree is not on an endangered tree list because there are so many of them still growing.
