Job's tears is sometimes cultivated for its edible seeds in sub-tropical areas[158]. It is a potentially very useful grain having a higher protein to carbohydrate ratio than any other cereal[57]. The seed has a very tough shell however making it rather difficult to extract the grain. The ssp ma-yuen. (Roman.)Stapf. is grown for its edible seed and medicinal virtues in China, the seedcoat is said to be soft and easily removed[57, 183]. This form is widely used in macrobiotic diets and cuisine[183]. The ssp stenocarpa is used for beads[57].
Plants have survived temperatures down to about -35°c[160]. (This report needs verifying, it seems rather dubious[K].)
Although classified as an annual, plants have often overwintered when growing in a polyhouse with us, they have then gone on to produce another crop of seed in their second year[K]. We have not as yet (1995) tried growing them on for a third year in a polyhouse[K].
