Air potatoes are a big invasive species in Florida--I hear eating them can be tricky--so it is best just to get rid of them. I have always hoped that someone knowledgeable would say oh, no, they are very edible for humans.

A potential problem with creating recipies for invasive species is that it could create a market/demand -- thus INCREASING the likelihood of spread, etc. While a nice idea to limit invasive species abundance (since will never eradicate once established), there is some potential pitfalls.

The Himalayan blackberries shouldn't be on the list. Harvesting the berries doesn't kill the plant. In fact, it could even encourage their spread, since most likely a few of the berries (or the seeds) will make their way to the ground somewhere else.

Folks have been eating it forever.....see below

Now if someone could just come up with a recipe for Kudzu...

Actually Kudzu is apparently edible, or at least the root. I read this in Emery's The Encyclopedia of Country Living. I don't know the details, so you'd obviously want to find out more in that book or elsewhere.

Kudzu produces very high quality edible starch. It has been used for this purpose for centuries in Japan. If you Google it, you can find out how to do it if you wish to use the kudzu. Goats also like to eat it.
