Lily,

I agree completely, one must know the history of the area to know if the edible plants are no longer edible. That's one benefit to making your yard into an edible landscape. You can control what toxins are dumped there.

Also, welcome! <img src="/images/graemlins/smile.gif" alt="" /> I grew up half way between Minneapolis and St. Cloud (my grandpa's farm is now a big outlet center <img src="/images/graemlins/mad.gif" alt="" />). I much prefer Texas as you don't have to shovel sunshine!
