Coral is from Sudan. Our original seed stock came from the grower for Experimental Farm Network. I agree with the observation it is little more difficult to thresh than others.
This longer maturing variety did not yield in 2019 enough viable seeds to consider selling. I have included a photo of the seed produced. I'm confident I'll find enough to germinate, I plan to try again. Although no more than 8 ft tall, the multiple super thick stalk diameters were impressive!
