Acer palmatum 'Atropurpureum' is a Japanese Maple known for its rich burgundy-purple, deeply lobed leaves that maintain their red color throughout the season before turning scarlet in fall. It's a slow-growing deciduous small tree or large shrub, reaching 15-25 feet tall with a rounded canopy. It thrives in moist, well-drained, slightly acidic soil, and partial shade, though it tolerates full sun.
