Recommendations:

*In all applications of LID, designing with native plant species is the preferred and strongly recommended option.  

*In all applications of LID, designing with native plant species is the preferred and strongly recommended option.  

*In areas containing, adjacent to, or within a linkage to an existing natural heritage feature , native plants should be used exclusively. In areas regulated by a watershed authority such as the CVC or TRCA, native plants will be required for approval.  

*In areas containing, adjacent to, or within a linkage to an existing natural heritage feature, native plants should be used exclusively. In areas regulated by a conservation authority, native plants will be required for approval.  

*In settings that have restricted or harsh conditions for plant growth (e.g. limited root volume, unusual patterns of drought and/or inundation, exposure to salt, sun, wind, shade and pollutants) introduced species can be used to substitute/augment native species selection. Introduced species shall be chosen to be functionally and aesthetically appropriate for the location.

Introduced species shall be chosen to be functionally and aesthetically appropriate for the location.  

*Introduced invasive species should not be planted as these can compromise the function of an LID practice, the ecology of nearby natural areas and can lead to higher maintenance costs. Non-native invasive species have not been included in the LID plant list.

*Except unless otherwise noted, the use of cultivars of native plants should be avoided.  

*Except unless otherwise noted, the use of cultivars of native plants should be avoided.  

*When sourcing native plant material, especially from commercial nurseries and garden centres, always refer to the scientific (botanical) name for the desired plants. Confusion over cultivated varieties of plants can be avoided by asking questions of the staff to ensure that only the correct native varieties are sourced. Species that are often mislabelled and other common concerns are noted in the Master LID Practice Plant List. Several nurseries specialize in the production of native plants, many of these nurseries are listed at:
