Experimenting with the edible day lily, hemerocallis fulva, which grows wildin most of the US. You can eat the flowers, flower buds, young stalks and tubers.

Wow another old one in drafts, but one I think I still want to post it. Has anyone on the plantblr scene harvested daylilies for food before? H. fulva and some of its very close kin/hybrids I know are supposedly edible.
