Camellia oleifera is a relative of Camellia sasanqua. This gorgeous anemony-form ‘Jaune’ cultivar with a ball of yellow petaloids is very rare in the United States. Three years ago I got a scion in our local camellia club, grafted it, and finally it is blooming in my garden.
A British horticulturalist Jennifer Trehane in her camellia encyclopedia mentioned doubts whether this plant a true C. oleifera. I second this: the leaves, stems, bark (and of course petaloids) are different from other oleifera seedlings and hybrids I have in my garden. Some DNA analysis is needed to be sure.
