The Shishi grows to 5' tall, though, right?

I only have 3' from the ground to the windows, and I don't want to block them too much :-O

$85 for the Chansonette, ouch!! At that price I might could afford one, but not the two I was hoping for. Do you think it's worth it?

Only worth it if you can't find them cheaper elsewhere. Also, shishi will stay short a long time & is very easy to prune in order to keep less than 36".

My plant of 'chansonette' stayed compact for many years but recently shot upward to about 8' tall and is also growing wider. 'shishigashiri' has remained under 5' tall and almost twice as wide without pruning for a long time. the individual flowers of 'chansonette' are more beautiful and a preferred color but i agree with doug that, based on size with regard to height especially, go with a 'shishigashiri' camellia.

i have seen pruned hedges of a white-flowered camellia, probably 'alba plena' if that would be acceptable for you.
