The vegetative propagation of medicinal species is becoming a basic tool for any cultivation in commercial scale. In this context, this work aimed to evaluate the propagation of spiral gingers cuttings, considering the type of cutting, presence of leaves and type of substrate for rooting. Two types of substrate were used: sand and a composition 3:2:1 (land, sand and humus). Cuttings of the apical and medium portion were tested, with either intact leaves, half leaf or without leaf, using a completely randomized design with 10 replications. The percentage of cutting survival, number of roots, number of buds, length of larger root as well as root dry biomass were evaluated within 60 days. The best rooting and number of buds were observed using the apical cutting with intact and half leaf. The medium and apical cuttings without leaf did not exhibited effective rooting in the tested substrates
