Probably Juniperus virginiana.

I want to make garden edging out of 3-4" diameter logs, 8 to 10" long
that are
placed vertically in the ground. I don't want to buy plastic or pressure
treated edging that I have seen at the home centers... What type of tree
cut
up in this manner would last the longest in the ground, untreated, that is
native to the central NY area?
Thanks in advance!
