Last summer I bought an unlabeled Japanese maple at Rarefind Nursery. It was a very healthy specimen at a great price. Between watching it leaf out this spring and looking at Rarefind's catalog for last year, I'm guessing that it could be an Acer palmatum 'Tsukasa Silhouette'. The leaves are quite small, the summer foliage is green, and the autumn foliage is red-orange. Any suggestions? Thanks!
