I'm not too sure what cultivar it is, i'm hoping it will bloom so I get a better idea.
I root pruned pretty heavily at the start of summer and re-potted it so i'm letting it recover this season.
I made all the cuts in winter last year, ill be doing the same this year on the top growth.
I'm trying my usual inorganic bonsai mix with about 10% garden soil added for more water retention. It seems to be able to grow in anything, the wind knocked it over into my pond last year and it kept growing like nothing happened.
