Green Ash
Red Maple

Green ash is a fast growing tree with incredible golden yellow leaves in fall. This tree is native to the prairies and is well suited for drought and cold. Green ash can also tolerate soil compaction, periods of flooding and a wide variety of soils including alkaline. This makes green ash ideally suited for use in urban environments.

Red Maple is a beautiful deciduous tree that blooms with small red flowers in the spring. It is one of the first trees to change colour in the fall, turning a brilliant reddish-orange colour. It is one of the most common and widespread maples in North America.

Red Maple is a great choice for parks and large gardens where there is ample room for its root system.

Important note: Red Maple leaves are toxic to horses if ingested in quantity.
