Fun Fact
Aspen bark can be peeled and eaten. Photo by T. Prendusi.
Aspen's inner bark can be peeled and eaten. It is often quite bitter but is more palatable in the spring. This inner bark layer is the food transportation network for the tree, so it contains a fair amount of sugar. Deer and elk like it too!
