Since 1906, the Ontario Horticultural Association (OHA) has led Ontarians in all things horticultural. Our organization is an integral part of this province's cultural fabric. (See OHA: From Then to Now). OHA was created by the Province of Ontario in 1906. It is a well-rooted tree with many branches 19 Districts); twigs (270 autonomous local societies) and leaves (over 30,000 members)!
