These are not the plants recommended for bioretention cells, rain gardens etc.
Bioretention cells, bioswales and similar structures normally have dry to moderate 'soil' conditions.
If you're looking for bioretention plants, you may choose from all of these grasses, perennials, shrubs, and trees.
The most common types of emergent vegetation used in North American wetlands are:
- cattails (Typha spp.),
- bulrushes (Scirpus spp.), and
- reeds (Phragmites spp.),
although a variety of other wetland vegetation can be used as well. In many cases, planting a monoculture may be recommended rather than attempting to support biodiverse vegetation, since the more “aggressive”, stress-resistant wetland plants (e.g., cattails) will quickly displace others if they are present. In surface flow wetlands, cattails and bulrushes are the most common types of emergent vegetation used. The most common type of plant used in sub-surface flow wetlands is reeds, but cattails, bulrushes, reed canary grass (Pharis arundinacea) and managrass (Glyceria maxima) have also been used.[1]
Some of the plants listed above have issues associated with invasive species and/or hybridization between native and invasive species. in Ontario
If you are uncertain, see the external links below for Provincial advice and specialist organisations that can help with plant selection.
