Crassula helmsii: Plant other species to suppress growth
Overall effectiveness category Awaiting assessment
Number of studies: 0
Background information and definitions
It has been suggested that the native species shoreweed Littorella uniflora can compete with C. helmsii, leading to reductions in cover of C. helmsii under some circumstances (Denton 2013). Denton (2013) suggests that there may be a chemical effect by which shoreweed inhibits the grown of C. helmsii.
