Acer griseum is one of our favourites! Acer griseum is a simply stunning small, slow growing deciduous tree which produces paper-thin curls of cinnamon bark on the trunk and main branches. These will become translucent in the light. The leaves turn a stunning red-orange in the autumn. Acer griseum has an eventual height of 8-12m and spread of 4-8m. Acer griseum prefers a sheltered position and moist, well-drained soil.
