Birds love to eat berries from the showy mountain-ash, especially in the winter when other food is hard to find.

The showy mountain-ash is found across almost all of Ontario, except for the southwestern tip of the province.   It can get up to 10 metres tall.

 

Its blue-green leaves have 13 to 17 leaflets which are 3 to 8 centimetres long.

 

Clusters of small white flowers bloom on the tree between May and July.  In August and September, the showy mountain-ash is covered in bunches of shiny red berries that are 4 to 6 millimetres across, and often stay on the tree through the winter. 

 

Size:  Up to 15 metres tall
