I have been doing a great deal of research on grain Amaranth, and vegetable Amaranth. There is a guy in Arizona who was getting inbetween one cup and one pound of seed per plant. He was planting Golden Giant Amaranth. My seed searches provided glimses at more and more info. One recent search turned up a seed seller on Amazon with excellent reviews, decent prices, and an extensive selection. Hirts Garden is the dealer. Amazon.com: Hirts: Seed; Perennial Patio, Lawn & Garden The following links are for the items I decided to purchase golden giant amaranth organic burgundy amaranth organic Hopi Red-Dye amaranth the 3 above are heavy yielding grain types molten fire amaranth Josephs Coat amaranth elephant head amaranth another grain type. A couple other comments on Amaranth. The protein in Amaranth is high in lysine, which accounts for 5% of total protein. It also has a very high "chemical score," a calculated value in which the higher numbers are the more perfect match for ideal human nutrition. For example, the chemical score for amaranth is 75-87, corn 44, wheat 57, sorghum 48, peanut 52, soybean 68, cow's milk 72. This stuff is great for you! Point 2. It should not be eaten raw. not the leaves, not the seed. Cooking, toasting, boiling or whatever elliminates any problems caused by eating it raw. The seeds raw will kill chickens if they are allowed to eat it raw in quanity. One other thing, as benificial as Amaranth is as a grain, IT HAS NO GLUTEN. it will not rise. Mix it 50/50 with wheat flour to make excellent healthy hearty bread. I have no connection with Hirts Garden what so ever, except as a customer impressed with their product. As I have read online... lol... Your Mileage May Vary. I will be planting test garden patches of the plant as both grain and vegetable this year, and will report back as I harvest my crop. I by no means am an expert gardener or plant expert. I can read and surf online however if something peaks my interest. Good Luck with all you plant this year, and please share both your successes and failures for info purposes for the rest of us. Thanks.
