A medium to to large deciduous tree that bears many similarities to shagbark hickory (Carya ovata), shellbark hickory occurs on rich moist bottomlands in eastern North America. It typically has a straight high-branched trunk and a narrow crown formed by relatively short spreading branches. The gray bark divides into large plates, which detach and curl back from the trunk, giving it a shaggy appearance. The pinnate leaves are divided into seven to nine glossy lance-shaped leaflets (compared to shagbark hickory's five), with one large leaflet at the tip and the others paired. The leaves are dark green above, yellow- or bronze-green below, and turn yellow in fall. Inconspicuous flowers appear in spring, with male flowers borne in drooping catkins on second year wood, and female flowers in short spikes at the tips of the new growth. Pollination is by wind. Green, spherical, thick-husked fruits ripen tan or brown in fall. Each fruit contains a tan or brown, hard-shelled nut with a small sweet brown kernel at its center. The flavorful, edible nuts are valuable to wildlife, including large birds. This tree has hard, heavy, dense wood that is valuable for furniture making, wood flooring and tool handles. Slow- and clean-burning, it is excellent for fuel or for adding a pleasing flavor to smoked meats.
Give this tree ample space and sunlight. Its long taproot grows best in deep well-drained soil. It requires and tolerates moister soils than does shagbark hickory. Use it in groups or as an individual specimen in parks, large residential properties, or naturalistic plantings. (source: learn2grow.com)

|1. Stratify the seeds. Stratification mimics the subjection to cold temperatures that hickory nuts require in the wild. Usually, squirrels facilitate this process by burying the nuts in the fall. The USDA recommends sowing seeds in a cold frame and letting them stratify for 60 to 150 days at 33 degrees Fahrenheit. They can also be stratified in the refrigerator, in 3 inches of moist sand.
Stratify nuts in 3 inches of moist sand for 90 days. Keep the stratifying nuts in the refrigerator, and keep the soil moist.
2. Plant pecans in the spring after the last frost. Pecans will germinate easily under favorable conditions, provided they have good soil and adequate water. Plant them 1 inch deep, and keep the soil moist. If the soil is heavy or otherwise poor, amend it with compost; half soil and half compost should work well.
3. Plant pecans in nursery rows for transplantation later on, or plant them where you would like them to grow. (info source: eHow.com)
