This tree was sold to a neighbour of mine as Acer circinatum â€“ Vine Maple. She still has the label that clearly states the name (and the name of the nursery that shall remain nameless), and she told me that it was pulled from a group of trees that looked very similar to the one she had purchased. Clearly this tree has little in common with A. circinatum, but the question is â€“ What is it? The leaves average 10-15cm in length, are consistently 5-lobed, are dark green and surprisingly leathery (much like a Prunus lusitanica leaf in texture). The new leaves are initially flushed red, then become distinctively glossy dark green by the summer, while the petioles maintain their red colouration. The tree is deciduous, with the leaves becoming red in autumn. The bark is striped green and grey-white (Section Macrantha). The tree stands about 3m tall, appears to grow relatively fast (30-70+ cm per annum) and apparently has yet to flower or fruit. I have searched the RHS Dictionary, among other books, and was unable to find any matching description. Any ideas?
