About

Acer palmatum 'Bonfire' is a compact, multi-stemmed tree that typically reaches heights of around 4 meters. Its growth habit is upright with short, twiggy branches. The leaves are palmate, featuring 5 to 7 slender lobes, showcasing a vibrant scarlet hue in spring that transitions to bronze and then green as summer progresses, ultimately turning a fiery red in the fall. During spring, it produces subtle red-purple flowers, which may give way to winged, purple fruits.

Leaf scorch can be caused by lack of soil moisture or excessive exposure. Suits container cultivation but attention to watering is needed in dry spells during the growing season. Suitable for bonsai cultivation. See Japanese maples cultivation
