Current research on the environmental impact of Veronica beccabunga in the Great Lakes is inadequate to support proper assessment. Although Veronica beccabunga is capable of forming large clonal stands (Grime et al, 1988) that can cover streams and significantly reduce native and wetland species (Mehrhoff et al, 2003), impacts are generally local.
There is little or no evidence to support that Veronica beccabunga has significant socio-economic impacts in the Great Lakes.
Veronica beccabunga has a moderate beneficial impact in the Great Lakes.
Veronica beccabunga is grown as an ornamental plant for butterfly and water gardens. V. beccabunga was shown to have higher rates of accumulation of nitrogen and phosphorus (P) than other herbaceous plants growing in stream banks and peat bogs. V. beccabunga shoots had P and N concentrations of 4661 mg/kg and 17,000 mg/kg respectively (Parzych and Jonczak, 2018).
The leaves were once cultivated as an edible, bitter green. V. beccabunga has been used for a variety of different medical purposes. It was used as an antiscorbutic and often eaten with watercress. It was also applied to wounds, bruises, and burns. V. beccabunga has been reported to be used for scrofulous affections, impurity of blood, swelling, and gout (Grieve, 1995). In the past, this plant was occasionally used to treat scurvy (Usher 1974). Nanoparticles extracted from V. beccabunga have been shown to have antioxidants and antimicrobial properties (Seçkin, H. and I. Meydan, 2021). V. beccabunga was compared to other ethnomedicinal Romanian plants and had the highest total antioxidant capacity out of any of the plants (Papp et al., 2019).
