Allelopathic potential of Helleborus dumetorum and its prospects for conservation with gardening

To tackle global biodiversity loss, we will need to sustain beyond protected areas. Here present a case study of rare and threatened native species Helleborus dumetorum. First, assessed by laboratory experiments if H. dumetorum has competitive advantage over weeds because its allelopathic potential; secondly, reviewed the literature discuss this could be conserved as an ornamental for gardening while at same time cultivation would benefit local biodiversity. Using bioassays, tested potential aqueous extracts leaves soil samples, collected or away from plants, on garden cress Lepidium sativum germination seedling development. The results confirmed presence allelochemicals in well effects where was growing, supporting Literature review combined with our observations field indicated more characteristics suitability purposes species’ conservational opportunities: easy successful transplanting, survival various habitats, no invasive potential, flowering early spring, long-lived leaves. Our shows, that considering plants ornamentals have multitude benefits
