'Iijima sunago' has been around awhile. At least since the 1800's in Japan, and with good reason. It's an attractive tree.
Spring coloured leaves are brown-red becoming more of a brick-coloured red with a greenish tint. Leaf colour then turns to shades of yellow, red and bronze, or sometimes described as purplish-brown. Hard to actually describe but fabulous to observe. The leaves also have little spots on them, like they had sand sprinkled on them and this is where the name comes from. Best leaf colouration will come from situating the plant in a sunnier location.
This interesting tree will grow to 10' or more in ten years and up to 26' over time.
