Filter strip vegetation can consist of turf grasses, meadow grasses, wildflowers and herbs, shrubs, and trees. Designers should choose vegetation that stabilizes the soil and is salt tolerant where the filter strip will be used for snow storage or to treat road runoff. Filter strips used for snow storage and treatment should be planted with non-woody vegetation. Vegetation at the toe of the slope, where ponding will occur, should be able to withstand both wet and dry soil conditions. The planting areas can be divided into zones to account for differences in moisture conditions and slope.

Trees and shrubs with deep rooting capabilities are recommended for planting to maximize soil infiltration capacity <ref>Philadelphia Water Department (PWD). 2007.

Although filter strips are often grassed, alternatives include forested filter strips or multi-zone filter strips, which feature several vegetation zones providing a gradual transition from turf to meadow to shrub and forest. The multi-zone filter strip design can be effective as a buffer zone to an existing natural heritage feature.
