Our growers keep suggesting that we try this pine as a replacement to the standard Eastern White Pine. The tree is said to stay somewhat shorter and narrower than the Eastern white Pine while being more resistant to winter burn. With that being said, we have begun using them as a substitute to White Pines at times. There seems to be some differing discussion as to the mature size of the tree. If I go with the consensus, you should expect around 30-50′ of height and 20-30′ of width. I love the White Pine and look forward to using this SW White Pine as the new and improved version. As the Scotch Pines die off, we will be looking for new options for a fast growing, reliable evergreen.
