2015 SPRING TREE & SHRUB INFORMATION
RED MAPLE (Soft Maple) – Acer rubrum The red maple is a medium-sized tree. The seeds of the red maple are contained in "keys" that float down from the tree's branches in early summer.
Size: 25 m tall, trunk 60 cm in diameter Moisture: Grows best in moist soil, but can tolerate different moisture levels Shade: Tolerates some shade Soil: Grows in a variety of soils
The red maple is a tall, straight tree in the forest, but in the open it tends to divide its main stem several times, often making it susceptible to breaking later in life. This is a good, fast-growing shade tree, but pruning and maintenance may be needed to keep its form strong if it is shading your house. Its roots are shallow, but they can spread widely, so make sure you plant your red maple where it will have room to grow. It's easy to recognize the red maple in the autumn when its leaves turn a beautiful bright red. SILVER MAPLE – Acer saccharinum The silver maple is a large tree. The silver maple is very similar to the red maple — except that its leaves turn pale yellow or brown, not red, in the fall. Its seeds are found in "keys" that fall from the tree in late spring. Bark on the silver maple's trunk is smooth and gray when the tree is young, and then becomes dark reddish brown and breaks into strips that peel off at either end and make the trunk look "shaggy". Sometimes, the trunks of silver maples are hollow, creating space for animals and birds to live in.
Size: Up to 35 m tall, trunk 100 cm in diameter Moisture: Prefers moist soil Shade: Slightly shade tolerant but prefers full sun Soil: Prefers rich soil
The silver maple is a large tree, so make sure it will have plenty of room to grow. It isn't a good tree to plant next to city streets, because it has a lot of leaves that fall off in the autumn and it has a lot of roots that can clog sewer pipes. The silver maple grows quickly — it's often planted to provide shade or to block unsightly views. SUGAR MAPLE (Hard Maple) – Acer saccharum The sugar maple is a large tree that can live for more than 200 years. The shape of the leaf is well known — it's found on the Canadian flag and the sugar maple is the national tree of Canada. In the fall, the sugar maple's leaves turn yellow, brilliant orange or red. Its bark is smooth and gray, and becomes darker and splits into ridges that curl out as the tree gets older. Seeds from the sugar maple are contained in "keys" which are produced every year, with an abundant crop every 7 years.
Size: 35 metres tall, 90 centimetres in diameter Moisture: Prefers moist soil Shade: Can tolerate shade but grows better when it gets full sun Soil: Prefers deep and rich soil
Sugar maples do best in deep, rich and well-drained soil. Its roots are deep and wide spreading, and it's a large and strong tree, ideal for use as a shade tree. Sugar maple gets its name from the sweet sap it produces which is used to make maple syrup. Other maples can be used as well, but their sap is not nearly as sweet. It takes about 40 litres of sugar maple sap to make 1 litre of maple syrup.

AMERICAN ELM – Ulmus americana American elm is easily recognized by its vase-shaped habit, with one straight trunk splitting into many arching branches. The leaves are oval-shaped, dark green, rough to the touch and have a very asymmetrical base. Tiny flowers appear before the leaves small clusters of circular, winged seeds mature in spring.
Size: 35 m tall Moisture: Prefers moist, but is adaptable Shade: Prefers full sun, tolerates part shade Soil: Prefers rich, well-drained soils
Dutch Elm Disease has reduced our classic urban shade tree relic survivors. Young and medium-aged trees can still be found in the wild. The American elm was one of our largest native trees before the disease, and most adaptable to rural and urban life. The long-term solution to destructive, widespread diseases is biodiversity in species, so you may plant disease-resistant elms. The University of Guelph Arboretum has been identifying large survivors and assembling a gene bank for breeding resistance. There are isolated American elm trees that survived Dutch Elm Disease with trunks over 4.5 m in circumference!
RED OAK – Quercus rubra The red oak is a tall tree with a thick trunk sometimes more than 120 cm in diameter. Acorns from the red oak are round with a scaly cap that covers less than ¼ of the acorn.
Size: 20 to 30 m tall, trunk between 30 and 90 cm in diameter Moisture: Can tolerate a variety of moisture levels Shade: Prefers full sun, but can tolerate some shade Soil: Grows in a variety of soils
The red oak needs room to grow — it can tolerate shade when it's younger, but needs full sun as it gets older. It doesn't grow very well if it's close to other trees. Sometimes dead leaves stay on oak trees, even in the winter.
BUR OAK – Quercus macrocarpa Depending on where it grows, the bur oak can be different shapes. It’s usually tall with a straight trunk but if grown in shallow soil, it can be smaller with a twisted trunk and gnarled branches. The bur oak is a medium to large tree and is the most common oak in Ontario.
Size: 15 to 30 m tall, trunk 60 to 120 cm in diameter Moisture: Tolerates a wide variety of moisture conditions Shade: Prefers full sun, but can tolerate moderate shade Soil: Can grow in a variety of soils
The bur oak’s roots grow deep into the soil, so plant it where there aren’t underground pipes. The bur oak can survive being transplanted and it grows well in cities. The bur oak can survive forest fires because it has very thick bark. It can also tolerate drought because its roots grow deep into the ground.

MOUNTAIN ASH – Sorbus aucuparia The mountain ash is a small tree. In May and June, the tree is covered in clusters of white flowers. Later in the summer, bunches of bright orange-red berries appear.
Size: 10 m tall Moisture: Prefers moist ground, but can survive in dry conditions Shade: Can tolerate some shade Soil: Grows in a variety of soils
Pretty flowers and leaves and bright colourful berries make the mountain-ash a popular choice for landscaping. The mountain-ash prefers moist ground but can also grow in rocky and dry soil, but it will be more stunted on rocky sites. Birds eat the fruit from the mountain-ash and they spread seeds, helping new trees to grow.
HACKBERRY – Celtis occidentalis Northern hackberry is the largest native hackberry, with distinctive warty-ridged bark as it matures. Leaves turn yellow in fall. Single, reddish-purple fruits hang below the leaves and may persist into winter.
Size: Up to 15 m tall Moisture: Wet to dry Shade: Full sun to partial shade Soil: Adaptable to all types and wide pH range
In a forest, northern hackberry will form a tall, high canopy, but when planted in the open, will grow as wide as tall, so give it ample space. It grows commonly in moist bottomlands near rivers and lakes but has proven to be a very adaptable species for dry, windy sites and urban areas. Northern hackberry is a suitable replacement for American elm. The sugar-rich fruit supports many species of birds, and the leaves are food for many kinds of caterpillars.
BASSWOOD (LINDEN) – Tilia Americana Basswoods are large trees with heart-shaped leaves with toothed edges and a short point. The twigs have a noticeable zigzag appearance. The fragrant yellow flowers and round grayish-brown fruit hang from the center of a leaf-like bract. When released, the bract acts like a helicopter wing and carries the seeds away in a breeze. This tree can be found often growing in large-trunked, multi-stemmed trunks along fencerows, or as singlestemmed trees within the deciduous forest. It is valued for its light, easily worked wood.
Size: Up to 35 m tall Moisture: Prefers moist soils Shade: Can grow in full shade or full sun Soil: Prefers rich, well-drained soils
It is common to rake up all the leaves in the yard in fall, but many species, including basswood have very nutrient-rich leaves. Mulching leaves with a lawnmower can help your lawn, your trees and save money on fertilizer. Bees love basswood flowers because they bloom in midsummer, when few other trees are in bloom.
