Canadian clearweed looks similar to the stinging Canadian wood-nettle. But they're easy to tell apart:

Canadian clearweed has:

  • leaves paired opposite one another on the stem (vs. Canadian wood-nettle's leaves staggered along the stem)
  • 3 major veins running nearly parallel down the length of its leaves (vs. Canadian wood-nettle's variable veins)
  • smooth stems (vs. Canadian wood-nettle's stinging hairs)
