Tables for identifying ideal species for bioretention are found in the [[Plant lists]]. See [[plant selection]] and [[planting design]] for supporting advice.

===Variations of Bioretention Cells===
 +
 +
Below, find three alternate Bioretention cell configurations, that differ based off whether developers want the system to infiltrate incoming water fully, partially, or not at all due to sites which possess contaminated soils or shallow bedrock, and/or zero-lot-line developments (i.e. condo developments and dense urban infill).
 +
 +
All the images below are image map drawings from the following pages to compare side-by-side the differences between varying configurations.

This design variation includes a surface overflow pipe/structure to allow excess water to leave the practice. A monitoring well is included so drainage performance can be evaluated over its operating lifespan.<span style="color:red">'''''Note''': The following is an "image map", feel free to explore the image with your cursor and click on highlighted labels that appear to take you to corresponding pages on the Wiki.''</span>
