Stormwater planters may be integrated into the landscape similarly to bioretention practices. Concrete curbs or vertical-walled planter structures are common features of stormwater planter facilities.  Through a study comparing the environmental impacts of bioretention systems of various design and construction material configurations, Sagrelius et al. (2022) noted that systems featuring large concrete structures (e.g., stormwater planters) incur higher environmental impacts than "soft-edged" bioretention cells when transportation-related factors associated with material production and delivery are considered. <ref>Sagrelius, P.O., Blecken, G., Hedstrom, A., Ashley, R. 2022. Environmental impacts of stormwater bioretention systems with various design and construction components.

As they do not require connection to the earth for infiltration purposes, stormwater planters can also be used in elevated locations. They are sometimes used in retrofit applications on otherwise impermeable surface, as raised beds or planters surrounding buildings. They can be employed to capture runoff from [[downspout disconnection| roof drains or downspouts]] or even upon terraces or vertical surfaces of buildings.

Over underground infrastructure, soils prone to subsidence, or on sites considered to be pollution hot spots, it may be necessary to prevent all [[infiltration]]. Stormwater planters are "filtration-only" BMPs, similar to bioretention cells, that can be squeezed into tight urban spaces, adjacent to buildings and within the usual setbacks required for infiltrating facilities. Stormwater planters can also be used as a means of providing building-integrated LID by capturing a portion of the rainwater from the rooftop.

This type of cell can be constructed above grade in any waterproof and structurally sound container, e.g. in cast concrete or a metal tank.

As stormwater planters are often quite small and receive very rapid flow, both a [[level spreader]] and the use of mulch and stone to dissipate energy from concentrated inflow are strongly recommended.
