A few years ago I noticed some sprouts coming from straw I used for mulch. I decided to raise the sprouts and save the seeds. I forgot about them until January. I planted them a few weeks later(by the way January's not very cold here in so cal)and I now have some grain heads and I have trouble finding out what they are. The grains on the head are arranged in six rows in the shape of a rectangle. The stalks are about 2-3 feet tall and do not branch anywhere above the ground, with an average of
2-4 stalks per plant. The husks do not come off with threshing but can be rubbed off with a person's hands. It has long awns. Could you please help me know what they are? There will be pictures in the attachment.
