Where it is found
Green ash trees grow across southern and central Ontario, as far north as the Ontario-Minnesota border and the north coast of Georgian Bay, east to the North Bay region.
This ash is popular as a shade tree in residential areas and was widely planted because of its good form although the Emerald Ash Borer is currently threatening the species across its entire range.
- Size: Up to 25 metres tall
- Moisture: can tolerate moist and seasonally temporarily flooded sites

When planting, you need to dig a large enough hole for the root to grow rapidly without too much strain. If you are digging in clay soil, the hole will need to be at least 6 times the width of the root ball.
