The intrepid adventurer, Merriwether (Houston, Texas) is teaching wild edible plant classes at the Houston Arboretum and other parks and nature preserves in the area. (The Arboretum people know him as Dr. Mark Vorderbruggen, but that means nothing...)
He also holds classes at the very primitive Old Riley Fuzzel/Peckinpaugh Nature Preserve on Saturdays or Sundays whenever three or more interested people schedule it.
(For more info on his classes, see the "On-site edible plant classes in Houston" thread in the Regional Events/Southern USA section here on the permie site.)
His website is Edible Wild Plants of Houston, Texas, and the Southwest – Merriwether’s Guide to Wild Edibles. You can find it at
http://houstonwildedibles.blogspot.com/ His Edible Wild Plants site has a list of edible plants in the right column, listed by the common name. When you click on a plant, it will show a photograph, the scientific name, what parts are edible, how to prepare them, where and when to find them, and if they have any other uses (or dangers). Very handy.
Please be sure to check out his common-sense list of Foraging Ethics on the home page of his blog. If you want to wipe out stands of plants by eating them, you’ll have to come to my place and work on the dandelions, bittercress, cleavers, sour cherry sprouts, wild mustard, some kind of garlic thing, wild blackberry sprouts and various grasses.
