Depending on where you live, you can often find them year round. It should be winter here, but it has been much warmer than normal and there are multiple little yellow heads around the yard. Enough to make a small batch at least, lol.
Try the dried root in a tea. Just chop up the dried root, add boiling water to 1 tablespoon of root to make an entire gallon of tea.
Good idea, thanks!
