*Where possible, a combination of native trees, shrubs, and perennial herbaceous

*In areas where less maintenance will be provided and where trash accumulation in shrubbery or herbaceous plants is a concern, consider a “turf and trees” landscaping model.
*If trees are to be used, or the bioretention is located in a shaded location, then ensure that the chosen herbaceous plants are shade tolerant.
*Spaces for herbaceous flowering plants can be included. This may be attractive at a community entrance location or in a residential rain garden.
