Alive is the wise woman, all this theory would depend on at what point did  was jefferon stranded in wonderland by Jefferson. Since the mad hatter was one of the individuals that Alice did intereact with, and based on his daughter  age I say it at most he could have been there for 1 or 2 years.

Personally I don't think the wise woman is Alice, but Cora. Who does know about Magic, and had herself been stranded from Wonderland for years. So it not really out their to say that Cora aka the Queen of heart would have known already about the Mushrooms.
