People don't seem to get excited about green leaves, but we were very excited by this Schefflera minutistellata and could not figure out why we haven't seen it before. The accession date is 2014, and there should be one from 2011 somewhere that we haven't seen. We liked the double circle of leaves. Here is the Schefflera delavayi that we have posted before. This is Idesia polycarpa, with nice tiers of leaves, and nice red leaf petioles. There are a few in this area, so hopefully, one is female. I like Tetracentron sinense leaves, and the only tree we knew was a much older one with leaves way up there, so I was happy to find this youngster.
