Sousa et al. (2016) tested how two plant species commonly used in northeastern United States green-infrastructure installations —Carex lurida (sallow sedge) and Liriope muscari (lilyturf)—respond to repeated drought and flood conditions expected under climate change. Both species tolerated flooding well, but drought caused more stress, reduced stomatal conductance, and significantly lowered biomass, especially for Carex lurida. Overall, both species survived repeated stress cycles, suggesting they remain viable for future GI installations, though drought poses the greater risk to performance. Note: STEP does not recommend Liriope muscari for LID projects in Ontario, as it is not native and can exhibit invasive tendencies.

Knappe et al. (2023) modelled dual-layer (upper vegetated substrate layer and a lower retention layer separated by a distribution fleece) roof designs to investigate water balance outcomes (storage, outflow, evapotranspiration) under wet and dry climactic extremes. During extreme climate years, the roof with the largest retention volume provided more evaporative cooling and retention of heavy rainfall events without outflow in summer, leading to a more climate-resilient design.
