About
Acer palmatum 'Atrolineare' is a small deciduous tree that typically reaches about 3 meters in height. Its leaves are slender-lobed and ribbon-like, exhibiting a dark red hue in their youth. As summer arrives, they mature to a bronze-green shade, before transforming to vibrant red and orange tones in the fall. This cultivar is well-suited for bonsai cultivation.

Care notes
- Cultivation

Leaf scorch can be caused by lack of soil moisture or excessive exposure. Ideal for container cultivation and bonsai training. See Japanese maples cultivation
