Camellia flowers throughout the genus are characterized by a dense bouquet of conspicuous yellow stamens, often contrasting with the petal colors.Most species of camellias also require a large amount of water, either from natural rainfall or from irrigation, and the plants will not tolerate droughts.One of these is the aforementioned C. reticulata, grown commercially in thousands for horticulture and oil production but rare enough in its natural range to be considered a threatened species.The German botanist Engelbert Kaempfer reported[15] that the "Japan Rose", as he called it, grew wild in woodland and hedgerow, but that many superior varieties had been selected for gardens.Europeans' earliest views of camellias must have been their representations in Chinese painted wallpapers, where they were often represented growing in porcelain pots.His gardener James Gordon was the first to introduce camellias to commerce, from the nurseries he established after Lord Petre's untimely death in 1743, at Mile End, Essex, near London.[16] With the expansion of the tea trade in the later 18th century, new varieties began to be seen in England, imported through the British East India Company.The camellia was imported from England to America in 1797 when Colonel John Stevens brought the flower as part of an effort to grow attractions within Elysian Fields in Hoboken, New Jersey.Their revival after World War I as woodland shrubs for mild climates has been paralleled by the rise in popularity of Camellia sasanqua.
Camellia reticulata
is rare in the wild but has been cultivated for hundreds of years.
