Ontario Trees and Shrubs
by Gordon Robertson
Trees are defined as a perennial plant with a long woody stem, usually called a trunk, that supports branches that in turn support smaller branches holding leaves or needles. In their maturity, trees usually reach heights exceeding six metres. Shrubs, on the other hand, are smaller than trees and may have multiple stems. Some plants can be placed in either category such as the Staghorn Sumac.
Trees can be either deciduous or coniferous. Deciduous trees are noted for seasonally shedding their leaves, but also flowers and ripe fruit, usually in autumn. Coniferous trees or conifers differ because they propagate by cones whereas deciduous trees propogate by runners, fruit, acorns, or keys (samaras). Many conifers are evergreens, meaning they stay green all year but some such as the Tamarack, or Larch, does not.
* Indicates non-native species
We have added, with the help of elders from Kitigan Zibi, the Anishinabemowin / Algonquin names to most of the trees in our database. The indigenous names are in green. Note, some trees have no Anishinabemowin name. If you have a reliable source for any Anishinabemowin name(s) contact us at Education@ofnc.ca.
