The foxtail &common reed in autumn/강아지풀 &갈대/狗尾草&芦苇

There is a long stream not far away from my house, both sides of the stream banks are the pathway for pedestrians for jogging or cycling. In Autumn, the foxtails and common reeds can be seen along the stream, the scenery is beautiful, especially when the wind is blowing...

离我家不远处,有一条很长的小川,川岸两旁是供行人徒步和騎自行车的好去处。 秋天,川岸两旁长满了狗尾草和芦苇, 景色优美,尤其是当微风吹的时候。。婀娜多姿!

Setaria viridis is a species of grass known by many common names, including green foxtail and green bristlegrass.It is a hardy grass which grows in many types of urban, cultivated, and disturbed habitat, including vacant lots, sidewalks, railroads, lawns, and at the margins of fields. It is the wild antecedent of the crop foxtail millet.
This is an annual grass with decumbent or erect stems growing up to a meter long, and known to reach two meters or more at times. The leaf blades are up to 40 centimeters long and 2.5 wide and glabrous

狗尾草(学名:Setaria viridis),又名绿狗尾草谷莠子狗尾巴草。一年生草本植物;秆直立或基部膝曲,高30-100厘米;叶片扁平,狭披针形或线状披针形;圆锥花序紧密呈圆柱形,刚毛粗糙,通常绿色或褐黄色


Phragmites, the Common reed, is a large perennial grass found in wetlands throughout temperate and tropical regions of the world.

 It can grow in damp ground, in standing water up to 1 metre (3 ft 3 in) or so deep, or even as a floating mat. The erect stems grow to 2–6 metres (6 ft 7 in–19 ft 8 in) tall, with the tallest plants growing in areas with hot summers and fertile growing conditions.

The leaves are long for a grass, 20–50 centimetres (7.9–20 in) and 2–3 centimetres (0.79–1.2 in) broad. The flowers are produced in late summer in a dense, dark purple panicle, about 20–50 cm long. Later the numerous long, narrow, sharp pointed spikelets appear greyer due to the growth of long, silky hairs.

Reed is used in many areas for thatching roofs. It can also be used for making baskets, mats, pen tips, etc.
