ontario woody plants

A new initiative aimed at improving the information exchange between landscape designers and growers is underway — in an effort to connect those who include their favourite trees and shrubs in their designs with those who are the most knowledgeable about plants grown in Ontario. Your feedback is needed on the master wood plant list below.
