===Underdrain===

Stormwater planters differ fundamentally from [[bioretention]] in that the storage function is provided only by the [[water retention capacity]] of the [[filter media]]. As such there is no storage reservoir and the only purpose to the aggregate layer is to drain water to the perforated [[pipe]]. For this, a medium aggregate as described in [[choker layer]] is recommended as it negates the need for a separating layer to the filter media.

*Stormwater planters routinely capture only rainwater flowing from adjacent rooftops. This means that [[salt]] may be less of a concern than in [[Bioretention: Parking lots]] or [[Bioretention: Streetscapes]].

*The [[plant lists]] are still a good place to start when selecting species for LID in Ontario.
