The goal of planting design for LID practices is to achieve a sustainable vegetation community that is tailored to the ecological qualities of the site and the aesthetic considerations of the landowner. Plant selection for LID practices is predicated on the principle of ‘right plant for the right place'. Many LID practices are carried out within a highly urbanized context that poses unnatural stresses on plant growth and survival. This guide provides general recommendations to direct species selection. Landscape professionals should use this information to generate specific plant lists that are tailored to the conditions prevalent on site while addressing surrounding urban and natural land uses.

*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 [[Bioretention: Plant lists]].
