A water loving creeping grass that spreads with long rhizomes and can form dense stands. Cottonwool grass grows in a poorly drained damp soil such as vleis and riverbanks. White flowers open from August to June. It is hardy to frost, fast growing and should be planted in the sun or semi-shade. This is an ideal grass for wetlands. It also protects the soil from soil erosion. It is also a useful grass as it is used for thatching, making paper and fuel. The seed also attracts birds. Named after Ferrante Imperato ( 1550-1625) an Italian scholar of many subjects. He also formed a museum and studies how fossils were formed.
