City of Cornwall Tree Planting 2016

City of Cornwall

The City of Cornwall plants a wide selection of tree species during the spring and fall. The tree planting variety list contains varieties best suited to grow in urban conditions.

Residents are welcome to request a particular variety, but City staff will make the final choice based on spring or fall planting, tree form, site space, overhead utilities, and the soil type in that particular area (details included on the variety list). The City relies on residents to help with the care of young trees. Residents are encouraged to deeply water the tree once a week in dry weather. Please use caution when using grass trimmers near the tree. Please do not trim or prune the tree.

The City appreciates the help of residents in caring for our trees and our environment.


Planting Tree Species List

The most common constraint for tree planting is the size of the area available for the tree, both above and below ground. Here you'll find a list of the trees the City of Cornwall plants sorted by size. 

Note: Links will open in a new Wikipedia window


Small Trees - less than 10 m (30')

It's a good idea to plant a small tree in a small space. A large growing tree might look nice at first, but after a few years it will require constant pruning to keep it away from things.

  • Amur maple - small ornamental maple, yellow/red fall colour, compact form, wide range of soils.
  • Tartarian maple - similar to Amur maple, with trident shaped foliage, good in calcareous (sweet) soils
  • Downy serviceberry- native, early spring white flowers, red fall colour, moist well drained soil
  • Ivory silk tree lilac - ivory coloured flowers in June, yellow/brown fall colour, well drained soil
  • Japanese cherry - Crimson point - spring pink flowering trees, reddish-purple foliage, purple fruit and fall leaf colour, wide range of soils. Spring planting only
  • European hornbeam - excellent foliage tree, four season interest with attractive bark, range of soils. Spring planting only
  • Globe maple - ball shaped crown, green foliage, yellow fall colour
  • Hawthorn - Cruzan - white to pale pink flowers, shiny dark green foliage, interesting twisted trunk. Spring planting only


Medium Trees - 10-15 m (30-45')

These trees are good for spaces where you can't fit a big huge tree, but you don't need a small flowering tree either.

  • Prairie gem pear - dense rounded habit which produces a blanket of white flowers in spring before the leaves emerge. Lustrous dark green leaves turn golden yellow to orange in autumn.
  • Turkish hazel - small oval leaves, may produce small nuts at maturity, dry sandy soil
  • Ironwood - small tree with a wide spreading crown, yellow fall colour, wide range of soils

Large Trees for boulevards - greater than 15m (45')

These trees are good for wide boulevards that don't have powerlines or streetlights overhead.

  • Skyline honeylocust - feathery foliage, thornless, yellow fall colour, good in calcareous (sweet) soils
  • Hackberry - native, elm like leaves, immune to Dutch elm disease, wide range of soils, drought tolerant
  • Homestead elm - disease resistant hybrid, yellow fall colour, wide range of soils, drought tolerant
  • Greenspire linden 'Silver' - heart-shaped leaf, yellow fall colour, good in calcareous (sweet) soils
  • Emerald queen Norway maple - dark green leaf, dense shade, yellow fall colour, wide range of soils
  • Crimson king Norway maple - dark red leaf, dense shade, brown fall colour, wide range of soils
  • Katsura-tree - beautiful foliage, yellow fall colour, not for very dry areas
  • Hardy rubber-tree - excellent shade tree, minimal pests, fall colour poor, soils variable. Spring planting only

 

Big Trees -greater than 15m (45')

These trees are the biggest of the bunch. At maturity, the canopy will be as wide as the tree is tall. Great trees for big lawns, boulevards and parks.

  • Red oak - native, fast growing oak, red fall colour, sandy loam soil . Spring planting only
  • Bur oak - native, red fall colour, soil variable. Spring planting only
  • White oak - native, green foliage turns to purplish-red in the fall, disease resistant and drought tolerant tree. Spring planting only
  • Kentucky coffee tree - native, open branching, bluish-green foliage, yellow fall colour. Spring planting only
  • Ginkgo - disease resistant, yellow fall colour, soil variable, drought tolerant
  • Sugar maple - native, yellow/orange fall colour, well drained soil
  • Native red maple - native, yellow/red fall colour, prefers moist but tolerates wide range of soils
  • Basswood 'Redmond' - large heart-shaped leaf, dark green leaves, requires large growing areas, wide range of soils
  • Native tulip tree - native, glossy leaf, yellow fall colour, tulip-shaped flowers, loose well drained soil
  • Amur cork tree - round, spreading canopy, yellow fall colour, fast growing
  • Shagbark hickory - edible nuts, interesting shaggy bark, well drained soils but adaptable, yellow brown leaves fall. Spring planting only
  • Yellowwood - smooth grey bark and fragrant smell, white spring flowers, yelow foliage in the fall
  • Butternut - large compound leaves, yellow fall colours, edible oval nuts
  • Black Gum - dark green glossy foliage, turns to orange and scarlet in the fall, disease and pest free
  • Horse chestnut - large compound leaves, flowers are white with a small red spot, edible red glossy nuts

Narrow Trees - greater than 15m (45')

These are tall growing trees, but the tree canopy doesn't get very wide. They're good for boulevards with a streetlight nearby, or close to buildings.

  • Columnar Norway maple - dark green leaf, yellow fall colour, soil variable
  • Autumn Blaze maple - Armstrong - fast growing, yellow to orange fall colour
  • American beech - native tree, bluish green leaf, bronze fall colour, produces nuts in the fall which are edible
  • European hornbeam - excellent foliage tree, four season interest with attractive bark
  • Princeton Sentry ginkgo - disease resistant, yellow fall colour, soil variable, drought tolerant
