Populus nigra; Black-poplar

This is a large Black Poplar found in Longford Park set back slightly from a main pathway. They are large spreading trees when fully mature with a domed crown with a thick, blackish gnarled bole. covered with distinctive burrs and tuberous growths. 


The branches are mostly ascending and the bole can be multi stemmed or one single straight trunk. This poplar has a thick trunk at the bottom that splits into two main boles going up straight.


The leaves are triangular or diamond shape and have variably long stalks. They have finely toothed margins and are fresh and shiny on both sides. The shoots and buds are smooth and golden brown when young. They also have reddish, pendulous male catkins and green female catkins.


The bark is grey-brown and becomes darker with age and becomes greatly fissured
