Shroomy, they look like Canadian roots, lots of tight wrinckles on the root and old for the size. Is it cold in your area?
Sad to hear of your fun comin to a close. Up here there ain't a season, just dig for what selling requires, but deer season starts at the end of Oct. so it's wise to call it quits for this year.
Frogger, thats the stuff, how can you get those two plants confused, maybe eatin some of them little marshrooms while diggin? Spikenard plants grow as big as a small bush, never mind the root difference.
Anyway I love the taste of the root for a tea.
