Hey great video! I've only ever harvested ostrich ferns for eating, have yet to try lady fern fiddleheads but maybe I should as I have around a dozen of them in my landscape. Happy foraging
There's a fairly common look alike in most regions that lady ferns grow: the spreading wood fern. It looks quite similar except they have more triangular fronds that end about halfway up instead of the lady fern's diamond shaped fronds that run almost all the way down. So pay attention to those hairy legs!
