Although wild pecans were well known among native and colonial Americans as a delicacy, the commercial growing of pecans in the United States did not begin until the 1880s.  The long cycle time for pecan trees plus financial considerations dictate that new varieties go through an extensive vetting process before being widely planted.

The seeds begin to germinate and seedlings grow in April. The nut harvest for growers is typically around mid-October. Extant examples of Engelhardioideae are generally tropical and evergreen, while those of Juglandioideae are deciduous and found in more temperate zones. Growth Rate This tree grows at a medium rate, with height increases of 13–24" per year. The period of pollination groups all cultivars into two families: those that shed pollen before they can receive pollen (protandrous), and those that shed pollen after becoming receptive to pollen (protogynous).  University of Georgia has a breeding program at the Tifton campus working to select pecan varieties adapted to subtropical southeastern U.S. growing conditions.. Seedling pecan trees result when a female flower on a known tree is fertilized by pollen from an unknown tree to produce a nut that then germinates.
