I am 6b, and the site is south facing with a fair bit of direct sun. 63 feet wide. There is a thriving linden, at least 80 feet tall on one side of the garden ... quite a big wingspan. On the other side WAS an 80 ft pine (not sure what kind). It got blown down in a windstorm and looking to replace it. Because the linden is so dominant, thinking the slimmer profile of a pine might indeed be the best offset/choice ... but wondering if anyone has any other thoughts. Was evilly looking at a monkey puzzle tree but know that would die over the winter. Magnolia? Tulip tree? Too fat? Birch? Another pine? Thanks for any ideas.
