This little evergreen popped up in the garden last year. I thought it looked interesting being so spindly.
Two votes for virginiana, eh? Hmm, the up close shots of the needles I find online look about the same but its overall look seems different. Maybe it'll grow into looking more normal.
It's a young seedling still in juvenile foliage (with needle-like leaves rather than scale leaves), and also in a shady situation, which makes it slenderer and sparser than it would be in full sun.
