Plant Wise

Plant Wise

Humans are largely responsible for the movement of invasive species from one area to another. Many human-assisted pathways have permitted the introduction of invasive species in Nova Scotia. One of these pathways is the garden and horticultural trade. Many invasive species are sold as plants for gardens. Unfortunately, they take over gardens very quickly and can quickly escape cultivation and spread into neighbouring ecosystems.

We have created a Grow Me Instead Guide which highlights some common invasive species used in gardens and offers native or non-invasive alternatives. This will help guide gardeners and landscapers choose non-invasive and native plants that will thrive in their gardens and not harm native ecosystems!
