Native to North America?

Yes

Sometimes confused with

Goodyera pubescens:
spike cylindric, equally dense on all sides, the spiral of flowers hardly discernible, and scape with 4–14 bracts (vs. G. repens, with the spike less dense, with secund flowers, and scape with 2-7 bracts).
Goodyera tesselata:
flowers spirally arranged, leaf blades with 5-9 nerves, and sac-like portion of lower petal (the labellum) longer than deep (vs. G. repens, with flowers usually arranged in a one-sided array, leaf blades with usually 5 nerves, and sac-like portion of lower petal (the labellum) as deep as wide).
