Schluggel do you know..

...Of a good weed identification(visual) guide that includes info. on weeds as indicators of soil condition? I would also like to know which plants bring up which elements. & indicators & accumulators... "Secrets of the Soil" references Ehrenfried Pfeiffer, "Weeds and What They Tell Us"...it's out of print, expensive, I can't find reviews on it, and I don't know if it's what I'm looking for anyway. I need pictures; I'm tired of cross referencing.
Thanks for responding. Love the stuff about "officinale/is" and "wort". also love the Japanese view...as my Grandfather used to say "A weed is just a plant out of place". :)
