Fullmoon maple (Acer shirasawanum, zones 5 to 9) ups the ante with leaves that have up to 13 lobes. This small maple grows 15 to 30 feet tall and wide, and prefers at least light shade, if not full shade. The cultivar 'Aureum' (shown) is a standout, with spectacular gold foliage. (Yet another gold foliage plant for shade!) It turns gorgeous shades of red and gold in fall.
