Is the root/rhizomes of ground elder edible? Ground elder is a terrible weed with delicious leaves. But is the root edible too?
Wikipedia:

Aegopodium podagraria, commonly called ground elder, herb gerard, bishop's weed, goutweed, and snow-in-the-mountain, is a perennial plant in the carrot family (Apiaceae) that grows in shady places.
[...]
The tender leaves have been used in antiquity and throughout the Middle Ages as a spring leaf vegetable, much as spinach was used.
I found this on http://www.dgsgardening.btinternet.co.uk/freefood.htm

Ground-elder
Aegopodium podagraria   all parts edible
young leaves in salads or cooked as a spinach,
roots dried and ground into a flour.
