I just read an article about a new book which gained lots of recommendations:
Steffen Guido Fleischhauer/Jürgen Guthmann /Roland Spiegelberger:
„Enzyklopädie Essbare Wildpflanzen“ - Encyclopedia on edible wildplants (of middle Europe)
This book describes about 2000 edible plants to be found in Middle Europe - how to find them, how to identify, nutrients and interesting substances (e.g. health issues), even culinary uses are included with descriptions of taste and texture and so on. I cannot believe it. I thought I was quite good in botany and know a lot about edible wild plants or wild plants for pharmaceutical use but 2000? I did never count them all but thinking about common herbs, the use of blossoms and wild root or leaf vegetables, fruits, seeds, nuts or edible tree leaves there must be lots. I am going to buy it and see what can be found in our area for some wild plant meals...
