The Acer palmatum 'Tamukeyama' (Tamukeyama Japanese Maple) is a highly esteemed, small, deciduous, weeping shrub or tree, known for its deeply divided, lace-like (dissected) leaves. It is widely considered one of the best red laceleaf maples for maintaining its deep purple-red color through the summer heat, often performing better in sunny, warm climates than other cultivars.
