Hybridization in pines

Both naturally and artificially occurring pine species (Pinus) can hybridize, combining their genetic material and sometimes creating hybrids that can be more or less vigorous than their parent species.

An example of a naturally occurring hybrid pine is Pinus × sondereggeri, a naturally occurring cross between loblolly pine (P. taeda) and longleaf pine (P. palustris).
