As a side note, narrowleaf plantain is one of the safe greens that don't need much getting accustomed to it, it is a very good option when there is any digestion trouble, to get them eating. As are leaves of roses, apple trees, blackberry and so on. It's always good to have a stash of those dried for emergencies.
I don't think broad leaf plantain is much different. It's very resistent to be trodden upon and grows more likely under difficult conditions.
