The trunk and branches are covered with prickly bark. This trait can be used to your advantage if you are trying to keep people and animals out of a certain area.
Growing Tips for the Japanese Angelica

You can reproduce the angelica tree by planting the seeds, dividing the suckers or taking cuttings. Grafting is necessary for named cultivars or the desired characteristics will not be found in the resulting tree.
Maintenance and Pruning
The Japanese angelica tree will not need yearly pruning unless parts have become dead, diseased or damaged. You may have to watch for any suckers and remove them to help keep the tree from cloning itself and spreading.
