ACER SHIRASAWANUM ATTRIBUTES
Besides the iconic leaf shape mentioned above, one other distinguishing features of Acer shirasawanum is the unique color of the bark. On older trees, the branches are clearly a silvery-white color with fairly smooth texture. Two of the most highly sought-after varieties are Aureum and Autumn Moon which boast yellow and orange color respectively!
GROWING ACER SHIRASAWANUM
Many Japanese maples are only hardy to Zone 6, but cultivars of Acer shirasawanum are generally hardy to Zone 5, making them a good choice for colder climates and areas of the upper midwest where most Japanese maples won't survive. The twigs and bark of Acer shirasawanum are also more resistant to burn and scald, meaning they are surprisingly tough yet relatively slow-growing ornamental trees.
