Acer palmatum 'Tamukeyama'
Tamukeyama Japanese maple
Tamukeyama develops a spreading, weeping framework clothed in deeply divided red leaves. It can grow more irregularly and upright than some other laceleaf selections before forming its cascading canopy. Dark red spring foliage generally carries red tones into summer, followed by fiery autumn shades that may include orange.
