A mame-size Satsuki

. . . with flowers that are too large.

Maybe it would look better with the flower buds just before opening. (The leaves look a bit chlorotic.)

The leaves ARE chlorotic. It is difficult to avoid that in such tiny pots that -- even with a 90% organic mixture -- need to be watered so often. I add epsom salts at least once a week, and fertilize with a full complement of minor elements, but hat they're growing so fast and blooming, yellowed leaves are seemingly unavoidable.
