It is considered a rampant and dangerous invasive weed in Australia, dominating the coastal dunes at the expense of native species and leading to deaths of native animals and birds when ingested. In India, ''Gloriosa'' is distributed in the Western Ghats but the density is rapidly decreasing due to excessive uprooting by herbal medicine producers.
