30 (50)cm, Job's-Tears Grass is a fast growing perennial grass which is usually grown as an annual. It descends from tropical Asia and has large, ornamental dark violet-black seeds fading to light grey with maturity and short, broad foliage. The seeds are roasted and ground in order to make a flour for bread. Easily cultivated in any rich, well drained, rather rocky soil in full sun. Sow directly to the ground after the last freezing nights in late spring or early summer. Alternatively cultivate as a perennial pot plant, keep slightly drier in winter at a minimum of some 20°C in full sun. VII-IX.
