You guessed right- another Camellia - Scented Snow, I agree it has a scent, compared to most camellias which smell like nothing, but I wouldn't say it was necessarily a pleasant scent. Just sort of herbacious. But a lovely flower it is with double petals and yellow stamens hiding in the center. The plant has a very tree like form, tall and statuesque.
This one is Autumn Moon pure white and a perfect formal double. When the petals fall to the ground, they are shaped like hearts. That's all for tonight, I'm a sleepy, sleepy garden girl.
