Other claims from this paper (8)

Intervention effect Drought cycles reduced growth and flowering of Lythrum salicaria.
Intervention effect Repeated consecutive drought and flooding cycles negatively influenced growth of both species in the same way.
Intervention effect Lythrum salicaria was more plastic than Knautia arvensis, allocating more biomass to roots during drought cycles.
Intervention effect Flooding cycles reduced root length of Knautia arvensis.
Intervention effect Drought cycles increased root diameter of Lythrum salicaria.
Intervention effect Drought cycles decreased root length of Lythrum salicaria.
Observation Both species had coarse roots (> 2 mm) that support infiltration through biopores.
Recommendation Wet-tolerant species are recommended for raingardens because they can benefit the system through higher water use.
