What is Imperata cyindrica

Imperata cyindrica , cogongrass or Chigaya (Scientific name: Imperata cyindrica) is a perennial weed of the genus Imperata in the Poaceae family, native to Africa, Asia and Australia. It grows naturally along shores and in grasslands throughout Japan from Hokkaido to Okinawa. The rhizome produces many stems that grow in clusters. In early summer, before the leaves open, the flower stalks extend and produce reddish-brown, tail-shaped flower spikes. The flower spikes consist of many lanceolate spikes. The base of the ear is covered with long, silvery-white hairs. It is considered a troublesome wild plant that is difficult to pull out because it spreads deep into the soil with its strong rhizome.
