Newmarket is located in the Lake Simcoe watershed in a region characterized by a mixture of broad leaf and coniferous trees, such as eastern white pine (Pinus strobus), red oak (Quercus rubra), sugar maple (Acer saccharum), red pine (Pinus resinosa), white ash (Fraxinus americana), American beech (Fagus grandifolia), and eastern white cedar (Thuja occidentalis).

The Town also includes 382ha of the Oak Ridges Moraine in the south west part. While Newmarket is north of the Carolinian forest zone some species representative of that zone such as American sycamore (Platanus occidentalis) and black walnut (Juglans nigra) are present.

​​​​​​​​​​​​​​There are many common trees that are planted by the Town of Newmarket's Parks & Property Services arborists on municipal boulevards. This page provides information on the types of trees you may encounter in Newmarket.

Autumn Blaze

Autumn Blaze Maple 

Botanical name: Acer x fremanii 'Jeffers Red'

Family name: Aceraceae

Commonly known as the Autumn Blaze Maple. It is a hybrid of red maple and silver maple that combines the best features of both. The Autumn Blaze has the vigor and adaptability of the silver maple along with the beauty and strength of the red maple.

 Like its silver maple parent, Autumn Blaze grows quickly. The growth rate of this cultivar is about four times faster than that of a red maple. Under optimal conditions it can grow 3 feet or more per year. Eventually it will grow to 50 feet tall and 40 feet wide.

 At maturity it will have an oval to rounded crown with ascending branches and a well-defined central leader. This tree is not as susceptible to storm damage as silver maple because it has superior crotch angles and a well-balanced branching habit (inherited from its red maple parent) but still has the weaker wood characteristic of the silver maple. It grows in a very uniform shape, so requires little pruning. 
 
Summer foliage is medium green. In the fall Autumn Blaze consistently develops brilliant, long-lasting orange-red color. This vivid color, as well as its rapid growth rate, is the main reason to plant this tree. It also has some winter interest , with the new growth retaining a red color after leaf drop that persists until the following season.

If you want a large, fast-growing tree with spectacular fall color, Autumn Blaze® maple is an excellent choice. This dependable selection of Acer x freemanii ('Jeffsred', P.P. No 4864) is a hybrid of red (A. rubrum) and silver (A. saccharinum) maple that combines the best features of both: it has the vigor and adaptability of the silver maple along with the beauty and strength of the red maple. It has received excellent ratings from all parts of the U.S. and is also very popular in Australia, New Zealand and Canada. 
 
Autumn Blaze® is very adaptable to a wide range of climate and soil conditions. It tolerates clay soil, and will withstand wet soil conditions and drought. This tree will grow in a wide range of climates from Wisconsin to central Florida, and is hardy in USDA zones 3-8. Consider it for a site that isn’t right for red or sugar maple, or as a more colorful alternative in place of silver or Norway maples.

With its distinct upright oval form, Autumn Blaze® is excellent as a specimen planting, but can also be used in groups. Because of it size it is most appropriate for the larger yard, commercial landscapes and parks. Its thin bark is easily damaged, so it's best not to use this tree in high pedestrian traffic areas. Autumn Blaze® has fewer problems with leafhoppers and verticillium wilt that adversely affect some slower growing maples. Since it's a seedless cultivar, you won't have to worry about weeding out thousands of seedlings.

English Oak

English Oak

Botanical name: Quercus robur

Family name: Fagaceae

Description: English oak is a majestic tree with a very wide spreading crown, a short sturdy trunk, and deeply fissured gray brown bark. It can grow to 140 ft (42.7 m) tall with a rounded spread of 80 ft (24.4 m) or more, but is usually smaller in cultivation. English oak has small deciduous leaves, 3-5 in (7.6-12.7 cm) long, with 3-7 pairs of rounded lobes, and extremely short petioles (leaf stems). They remain deep green long into autumn before turning brown and then persisting on the tree well into winter. The typical oak flowers are hanging catkins which appear with the emerging leaves in early spring. The acorns are elongate, about 1 in (2.5 cm) long, with a cup that covers 1/3 of the nut. 

picutre of an english oak tree 

Culture: English oak is tolerant of acidic to alkaline soils. It grows only a foot (0.3 m) or so a year in youth but can live more than 700 years. 

Light: Full sun.

Moisture: English oak does well with regular watering. It cannot tolerate extended droughts. Powdery mildew, a fungus that grows on the leaves, can be a problem in humid climates.

Hardiness: USDA Zones 4 - 8. Cold hardiness is variable and even mature trees sometimes are killed by a hard winter freeze. Nor is English oak well-adapted to the hot, dry summers of the middle or southern U.S. Outside its native range, English oak is best adapted to Canada and the northeastern U.S., in zones 5 and 6.

Propagation: Oak species are propagated by seed. The acorns are planted as soon as they mature and left outside over the winter. Named cultivars are propagated by grafting. Fast growing sucker shoots (sometimes called "water sprouts") are grafted onto seedlings of the same or a related species.

Shademaster Locust
Botanical Name: Gleditsia triacnthos var. Inermis 'Shademaster'

Family name: Fabaceae

Description:
One of the finest and most popular shade trees, valued for its delicate, ferny appearance which casts a dappled shade below; upright spreading and fast growing, seedless, very tolerant of adverse growing conditions, makes a great 

Ornamental Attributes:
Shademaster Honeylocust has dark green foliage throughout the season. The pinnately compound leaves turn an outstanding yellow in the fall. The flowers are not ornamentally significant. The furrowed khaki (brownish-green) bark is not particularly outstanding.

Landscape Attributes:
Shademaster Honeylocust is an open deciduous tree with an upright spreading habit of growth. It lends an extremely fine and delicate texture to the landscape composition which can make it a great accent feature on this basis alone.
This is a relatively low maintenance tree, and is best pruned in late winter once the threat of extreme cold has passed. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
Shademaster Honeylocust is recommended for the following landscape applications;

Plant Characteristics:
Shademaster Honeylocust will grow to be about 45 feet tall at maturity, with a spread of 40 feet. It has a high canopy with a typical clearance of 8 feet from the ground, and should not be planted underneath power lines. It grows at a fast rate, and under ideal conditions can be expected to live for 70 years or more.

This tree should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments.
