I posted a few links to QAL up the thread; I never ate it, but from what I read the roots are edible but not really yummy food. Edible. As long as one doesn’t pick poison hemlock which looks similar.
Its good to learn the differences in the plants. We’ve been here a long time and over the years have pulled many QAL out of my yard when it grows where I don’t want it. It does smell like carrots. I’ve just always composted it.
I purchased some books this winter on foraging and discovered a lot of edible plants growing on our property. Good to know in case my garden doesn’t do well or I feel a bit adventurous in my meal preparation.
