'Winter's Fire' is one of the fall blooming camellias at the USNA
Most of the "Hardy fall flowering Camellias" (USDA Zone 7a/6) available in the trade were developed at the Arboretum by Dr. William Ackerman. They were principally hybrids between Camellia oleifiera, C. sasanqua, C.hiemalis / C. vernalis. Their blooming patterns are variable depending on the weather. Typically, depending on the cultivar, flowering begins in October and continues, weather allowing, unabated through the winter holidays. Often we get a shot of cold (or two) during this period; sometimes this blasts the fully open flowers, but when temperatures rebound buds resume opening and unless it got really cold, another spell of flowering commences. Right now there are as many flowers open as I have ever seen in this collection.
