Definition of non-tunicateCategorized under "General"
Definition as written by Wingnut:
This term is used to describe bulbs such as lilies who do not form concentric rings around the growth point as is seen in onions and amaryllis, but consist of exposed "scales". These types of bulbs also do not have the protective "tunic" of dried ring layers that amaryllis and onions do, so are more easily damaged by digging.
