Overview
Acer palmatum is a graceful, layered small tree prized for its finely lobed leaves and brilliant autumn colour (reds, oranges, golds depending on form). Best in morning sun with afternoon shade and shelter from hot winds in SA. Ideal as a feature tree or for courtyards and large pots (dwarf forms), providing four seasons of interest.
