Abstract
Camellias are grown out-of-doors along the East Coast from Maryland to Florida, westward through the Gulf States to Texas, and along the West Coast from southern California to coastal Oregon and Washington. This region, described roughly as the “Camellia Belt” is responsible for most of the camellias grown in the United States. Beyond this region there are scattered plantings, usually under protected microclimatic conditions, subject to severe winterkill during periodic colder than normal winters.
Abstract
A series of crosses were made between genera within Theaceae including Camellia, Franklinia, Stewartia, and Tutcheria. Two valid intergeneric hybrids were obtained between Camellia and Franklinia alatamaha Marsh. The first, a C. japonica L. (2n=30) × F. alatamaha (2n=36) hybrid with 33 chromosomes, was intermediate in phenotypic characteristics. The second, a C. sasanqua Thunb. (2n=90) × F. alatamaha (2n=36) with 63 chromosomes, was phenotypically very similar to the C. sasanqua parent.
