Fraser fir – Abies fraseri – This classic conifer with upturned branches is sometimes called ‘Southern Balsam’ since it closely resembles Balsam Fir and grows mainly in the Appalachian Mountains, where it is considered endangered. Fraser Fir is frequently found in damp and fragrant woods in southeastern U.S. along with red spruce and mosses and ferns. In Canada it is grown primarily as a Christmas tree and is greatly preferred for that use due to its long-lasting, fresh-smelling needles.
This tree can be found by following the Arboretum circle road around past the south parking lookout, then going into the circle about 15 metres to a small clearing where it is planted amongst other conifer trees. A mature Fraser fir can grow up to 20 metres in height, with a width of up to 10 metres.

Red oak– Quercus rubra – This beautiful and hardy native species is a popular shade tree. In the open, it has a more rounded form than most oak trees; in the forest, it grows tall and straight. Its leaves emerge with a bronze-red colour, and turn a deep scarlet in the fall. Red oak is an important lumber tree used for furniture and flooring among other applications, and many birds and mammals feed on the acorns. Red oak can grow to 20 metres in height and width.
This tree is planted right next to the path that runs southeast toward the canal, down in the lowland area just west of the Arboretum’s little island. Follow the path past the intersection with the other paths, a little further along from the bench up on the hill, and look for the tree on the left side of the path.
Rancho Cherry – Prunus sargentii ‘Rancho’ -This is an upright-to-rounded cherry tree with beautiful pink flowers that come out before the leaves in early spring. The Rancho variety is an American clone of a beautiful Japanese cherry tree. The bark takes on a glossy red colour, and the leaves turn a bronze colour in the fall. Rancho is more resistant than many other cherries to disease and weather conditions.
This tree is planted not too far off the north path that runs from Building 72 toward Preston Street. It is located down the hill on the right side as you go north, about 40 metres north of the Katsura tree next to the path. Rancho cherry will grow to about 8 metres tall at maturity, with a spread of 4 metres.

Colorado Spruce – Picea pungens -This popular western U.S. spruce is planted widely throughout North America for its colour and symmetrical layered form. The dense canopy is thick with stiff and prickly needles. The needle colour ranges from dark green to the silver blue that has identified the species as ‘Blue spruce’ (although some varieties are bluer than others). As the trees mature, the older foliage darkens while the tips of new growth are a contrasting glaucous blue.
This tree is located in the Arboretum circle, about 6 metres west of the Fraser Fir (see Fraser Fir location). It can grow as high as 50 metres in the US west but will likely stop at half that height in this site and climate. When grown in the open, Colorado spruce keeps its branches all the way down to the ground.
