In this article, you’ll learn about the Norway pine with details such as uses, varieties, common diseases & pests, and the hardiness zones provided.
Also called the Red Pine, we’ll be looking at most ideal soil type to grow this tree, its essential features, and several others.
Norway Pine Trees
Contrary to what you may think, Norway pine trees have nothing to do with Norway.
It’s believed to have gotten its name given from English settlers who thought it shared some resemblance with the Norwegian Scotch pine.

An interesting fact about the Red pine is that Minnesota is the only state where it’s called the Norway pine. In terms of size, this tree has a moderate growth rate.
At maturity, it reaches heights of around 75 ft. However, such size can be exceeded to about 100 ft. with optimal conditions.
