About Us
The Thornhill Garden & Horticultural Society's members have a common interest in gardening and the greening of our homes and community through horticultural activities.


Our Society promotes the beautification of Thornhill's public and private spaces by:
Planting and maintaining trees, plants, shrubs and flowers at several community locations including:
-
Bayview/John Garden (southwest corner of Bayview Ave. and John St.)
-
Percy Bone Parkette (located in Thornhill Park)
-
Richard A. Jarrell Memorial Garden at the Thornhill Village Library
-
Alzheimer Society of York Region Magna Sensory Garden (10 Harlech Ct.)
Our Society's members continue to pursue activities and programmes which ensure that we remain relevant and resourceful in an ever-changing time and climate.
We are proud to carry on the vision a few gardeners had in 1914 - that of a Horticultural Society which would promote, and contribute to the beautification of the Thornhill community.
