I tend to agree with 1sagitarius on his point. While there may be nothing wrong with sawtooth, I' d consider the land use 50 years down the road before planting alot of them.

Today on our property, we deal with Morrow' s Honeysuckle - that was planted in the 1950' s as " Natural Fencing" that never really worked, but is all but inedible, and reproduces very well, I might add. Others have to deal with Multiflora Rose, or other introduced Pines or plants.

Just consider your options, and longterm plans before planting.
