Ilarian Japanese Maple

Ilarian Japanese Maple (Acer palmatum 'Ilarian')

Ilarian Japanese Maple (Acer palmatum 'Ilarian') is a striking dwarf selection known for its dramatic spring color and compact, globe-shaped habit. Emerging leaves are a rich burgundy-red flushed with pink tones, gradually transitioning to deeper maroon through summer. In fall, the foliage blazes with fiery red-orange tones. Its slow growth and small size make it ideal for tight spaces, rock gardens, and container displays where year-round structure and color are desired.

Distinctive Features

'Ilarian' is a true dwarf maple, typically reaching just 3 to 4 feet tall and wide in 10 years. Its small, five-lobed leaves are closely spaced on short internodes, giving the tree a dense, tidy appearance. The vibrant red hues in spring create a bold contrast in garden beds or against green foliage, while its symmetrical, rounded form adds architectural interest throughout the seasons.
