Nice gyoten!!!
This is a VERY GOOD SATSUKI!!! This gyoten has many different flower types. I will share with you. On the last flower picture, the flower with the pure white and pink sections is called O-shibori. A plain white flower, may or may not include a blotch of pink, are called Shiro-muji. The plain pink are called jiai-zaki. Those are the major flower types I see on this tree. If it was my tree, I would only have let a third of the flowers open. When you let it massively bloom like that, the tree uses up so much energy and can really stress a tree. Now if this was a japanese satsuki festival, that would be fine, but the trees they let bloom are not considered bonsai, and are in bigger pots usually. Be careful with this one. Very nice tree!!! Thanks for the post, I enjoyed seeing these pics.
