When I lived in a city I helped manage our neighborhood's community garden. I was able to get rare and endangered seeds from the USDA for free and we grew them in our community garden to experience ancient foods. Pretty cool program, I believe all we had to do was agree to not use them for profit and make an effort to return some seeds at the end of the season.

The Iranian sorghum was the most memorable plant. I had never seen sorghum before then and it is such an interesting plant. I have since developed a love for sorghum and sorghum molasses makes up almost all of my sugar intake these days.

If you have never seen sorghum, imagine 10+ foot tall corn stalks with amaranth heads.
