They can get well over one hundred feet tall and as they get taller the lower branches will self prune, resulting in tall trees that won't produce much shade. They are not true pines and their natural environment was a tiny little thing shared with fewer than two hundred varieties of other plants.
Did not see anything suggesting allelopathy, but it would seem they are not likely to be adapted to working well with the vast majority of other plants, coming themselves from such an isolated environment.
With them getting so big, and some implications from Florida experience that they are not very strong, I might have concerns about having them near my house.
Interesting history they have.
Every time you till, you lose 30% of your organic matter. But this tiny ad is durable:
