Green synthesis of metallic nanoparticles has lured the world from the chemical and physical approaches owing to its rapid, non‐hazardous and economic aspect of production mechanism. In this study, silver nanoparticles (AgNPs) were synthesised using petal extracts of Hibiscus rosa‐sinensis . The AgNPs displayed characteristic surface plasmon resonance peak at around 421 nm having a mean particle size of 76.25 ± 0.17 nm and carried a charge of −41 ± 0.2 mV. The X‐ray diffraction patterns displayed typical peaks of face centred cubic crystalline silver. The surface morphology was characterised by scanning electron microscopy and atomic force microscopy. Fourier transform infrared spectroscopy studies confirmed the surface modifications of the functional groups for the synthesis of AgNPs. Furthermore, the synthesised AgNPs displayed proficient antimicrobial activity against pathogenic strains of Vibrio cholerae , Escherichia coli , Klebsiella pneumoniae and Staphylococcus aureus .
