Annual, full sun, grows readily, needs zero attention.
takes heat, drought, and neglect, which is perfect for me.
Spacing 8" does fine for me, rich soil would be expected to produce much larger plants than what I got.
Looks like corn.
My poor production saw 1 seed in, 100 seeds produced. Rich soil should see more, as the side shoots did not produce much in the way of seed heads.
For syrup production, it is my understanding that the plant can be harvested after the seed heads mature. This allows grain production as well as syrup. The stalks need to be run through a press. Considerable pressure is needed to squeeze out the juice. Used cane mills are on Craigslist down here every now and then in the $1500-3k range. Boil the sap to remove water content as you would maple syrup. The baguesse (leftover leaves and pressed stalks) can be used for silage, mulch, fuel or compost. A couple hundred plants will produce a gallon of syrup.
