Moist to wet grassy meadows, vernal seepage areas, marshes, roadside ditches; at low to middle elevations (Pojar and MacKinnon 1994).
Fine to well-drained.
Tolerates poor soil conditions (Tenenbaum et al., 1994).
Mildly acidic to alkaline (pH 5.5 to 7.5) (Henderson, 1976).
Dry to fresh (Tenenbaum et al., 1994).
Full sun to partial shade (Tenenbaum et al., 1994).
Considered a "weedy" species and a good colonizer (Alverson, 2002).
No information but probably a component of moister meadows in Garry oak ecosystems.
