I picked this up at a DiY store half price..it’s tagged Katsura but looks nothing like my 2 mature Katsura’s, that have half the sized leaves compared to this one and the shape of the leaf and colour are different- any ideas please. I couldn’t help myself for just over a tenner! The leaves are in the larger end of the Palmatum group, are deep green, with deep serrations and slight twisted lobes. Maybe “Going Green? But looks a bit different
No, doesn't look like Katsura at all. It's not grafted, you probably have a seedling rather than a cutting or air-layer : a unique specimen ! ;-)
