Falsely Named

This native grows throughout the continental U.S. and it's often found in association with Solomon's Seal, with which it shares similar leaves. Its common name is variously False Solomon's Seal, False Lily-of-the-valley and False Spikenard - poor plant, it only seems to be nameable in terms of being a false version of something else! The scientific name is Maianthemum racemosum.

The tiny little flowers look like mini cauliflowers to me.
