Mine is also a plant from Esveld, and I agree: the red petioles and ribs make this very showy. It is growing very enthusiastically from a whip, with bright red young leaves. Hopefully flowers next year... Thanks for the picture Alex! -E
Another Section Palmata, Series Sinensia A. campbellii relation from SE Asia (China, in this case). Sounds like it needs care in placement and will not be for everyone. Their book Maples for Gardens says "It is of botanical interest but is not a very successful plant in cultivaton. Its leaves tend to shrivel in the sun and there is almost no fall color"
