` Good choices for swales with significant periods of flow, such as those downstream of a Level 2
or 3 detention facility.
Note: Cattail (Typ e latifolia) is not appropriate for most wet sweles because of its very dense
and clumping growth habit which prevents water from filtering through the clump.
