Trees from different countries

How adding different trees from different countries, then we would have more variety of wood. Like the Japonicum Aconitifolium, which is a Japanese version of a maple tree with red leaves.The Sorbus Aucuparia or known as the Rowan tree which is in Germany, this tree has green leaves and bright red round berries.They bloom into flowers in the spring, and drop the flowers in autumn. Or the Rubber Euthorbia tree from south Africa. These trees are completely green and look like cactus, but if you cut pieces of them, it's a good source of liquid if you aren't near an river or ocean. This tree also can heal your wounds if your massage the inside of the plant on the wound.
