Found this one on several websites (camforest, camtoocamellia, etc). It produces a white, early blooming, formal bloom. But it is labeled as a sasanqua.
If you have it, would you mind answering a few questions?

1. Exactly when does it start to bloom for you?

2. And do the leaves in your shrub handle lots of sun as well as sasanqua leaves normally do?

3. Are the leaves about the right size for sasanqua camellias (i.e., smaller than japonicas)? I could not tell from the limited nbr of pictures I saw online.

I am considering getting one but, the advertised shrub seems suspiciously like a japonica. whose leaves would not do well -in the sunlight exposure department- on the intended location. A sasanqua with its hardier leaves probably would be ok.

I was thinking that this shrub may just be a misrepresented early flowering japonica instead, in which case the leaves might get burned in the location I am planning to put it in.

By the way, Autumn Moon is a synonym. Its 'real name' is Marie Kirk.
