Eastern White - Pine Pinus strobus

Ontario's Provincial Tree! This tall and stately conifer was once a favourite for ship masts as well as furniture. Wind-blown white pines are also a hallmark of northern lakes and, subsquently, landscape paintings. Dense branching provides roosting and nesting sites for Great Horned Owls and Red-tailed Hawks.

The Arboretum's Century Pine Collection is made up of Eastern White Pines that were planted in 1907 and is likely the oldest pine plantation in Canada.
