Populus canescens (Grey Poplar)
Native: South, central, western Europe, including Britain
Location: Commonly grown for ornament and shelter, especially by the sea.
Leaves are covered with a white down which falls away remaining only on undersides and sometimes only faintly. Some consider this to a hybrid between White Poplar (Populus alba) and Aspen (Populus tremula).
Flowers open in March, males red and silky grey, about 5-10cm long, females greenish and silky about 2-5cm.
Fruiting catkins are about 10cm long and release cottony seeds in June.
