The Coix Halliana is a scarce, tall plant and can be found only deep within caves. It blooms once a year, for 1 month. It has tiny, spear shaped leaves, which are usually light green. It also grows small flowers, which can be purple, light bronze, dark pink, dark red and blue. These plants grow alone, but within a decent distance from each other, but it's very easy to control and maintain their growth. They can be used to clean land. As a defense mechanism the Coix Halliana tastes horrible, when eaten raw. They rely on wind pollination to reproduce. Once pollinated, they grow small, inedible fruits.
