Emperor 1 Japanese Maple

Emperor 1 Japanese Maple (Acer palmatum 'Wolff')

Emperor 1 Japanese Maple (Acer palmatum 'Wolff') is a standout red-leaf cultivar known for its rich color, upright form, and adaptability. This vigorous yet compact tree emerges in spring with deep reddish-purple foliage that maintains its vibrant color throughout summer, even in full sun. In fall, it delivers a dazzling display of crimson before dropping its leaves to reveal a striking winter silhouette. Emperor 1 leafs out slightly later than other varieties, helping it avoid damage from late frosts, making it a smart and reliable choice for cooler climates.

Distinctive Features

'Emperor 1' features classic palmate leaves with five to seven lobes, emerging a rich wine red in early spring and holding their color through summer heat. With a strong, upright branching structure and a mature height of 15 to 18 feet, it forms an elegant, vase-shaped canopy. Its relatively fast growth and consistent foliage color set it apart from older red cultivars like 'Bloodgood', while its frost resistance adds dependability to its ornamental appeal.
