Broomcorn brush turns from pale yellow to light green before maturity. It should be harvested when the entire brush is green from the tip down to the base of the peduncle. The fibers will be weak at the bottom if they are harvested while the lower ends are still yellow. The brush often begins to redden and become less flexible about 4 or 5 days after the proper stage for harvesting.
Rye (Secale cereale) is a grass grown extensively as a grain, a cover crop and a forage crop. It is a member of the wheat tribe (Triticeae) and is closely related to barley (genus Hordeum) and wheat (Triticum). Rye grain is used for flour, rye bread, rye beer, crisp bread, some whiskeys, some vodkas, and animal fodder.
Spelt (Triticum spelta; Triticum dicoccum), also known as dinkel wheat or hulled wheat, is a species of wheat cultivated since approximately 5000 BC. Spelt was an important staple in parts of Europe from the Bronze Age to medieval times; it now survives as a relict crop in Central Europe and northern Spain, and has also found a new market as a 'health food'.
