For those who are interested in growing chia in their home gardens, this website provides some useful information.
Plants for A Future is a British not-for-profit that maintains a wonderful, carefully researched database of useful plants. It seems to be affiliated with the permaculture movement. Its readers are knowledgeable, so the comments are often quite useful.
Unfortunately, the organization seems to have fallen on hard times and is "selling the farm." I hope that some other organization can step in to preserve the valuable information that's on this website.
