So I went to the Depot yesterday to pick up some potting soil. I happened to notice some new additions to their JM stock. There were about six or seven trees all about 5 feet high, green,healthy and all marked with same information. It was definitely different than anything I have now and for $35 I couldn't pass one up. The hang tag identifies them as Acer Palmatum with a picture of a red dissectum. The receipt says it's an Acer Dissectum Green. The back of the hang tag has a Plant Code identifier of THDA1601 which brings up the following link: thehomedepot.jhc.com/plant.aspx?plantcode=thda1601 The picture there looks like an Atropurpureum. So I'm guessing that's what it is but why is it green? Too much sun? Not enough sun?
It looks like the generic 'green' acer palmatum to me. Do you suppose a grafter had some unused root stock and was 'cleaning house'? BTW, generic green is a great for bonsai.
