Acer rufinerve

In its native Japan, the rust-bearded maple can grow up to 12 m tall. In our climate, it grows as a slow-growing, small tree or large, multi-stemmed shrub, reaching a height of 6–8 (–10) m and a width of 4–6 (–8) m. Distinctly upright, ascending branches form a broad, funnel-shaped crown.
