The Crimson Queen Japanese maple tree, a variation of standard Japanese maples, is one of the prettiest of the dwarf trees available. Not only is it beautiful in the spring and summer, but it also has amazing fall foliage as the maple keeps its bright-red leaves, and the cascading habit offers some winter interest. The typical tree is about 10 feet tall, compared to other types of maples that can be up to 100 feet. Therefore, the Crimson Queen will fit into tighter spaces than other types of maple trees can. Additionally, Crimson Queen is one of those sought-after plants that will grow under black walnuts. It likes partial to full, sandy, loamy, moist but well-drained soil.
