Method for the production of young plants and/or micro-parent stock of 5 herbaceous ornamentals. Method for the production of young plants and/or of micro-parent stock of herbaceous ornamentals, which comprises an in vitro culture phase during which explants obtained from parent stock of species to be propagated, or derivatives of these explants, are subjected to micropropagation which is carried out under suitable conditions and on suitable culture media, in order to produce microplantlets which, when subjected to an in vivo culture phase, are intended to develop into plants or into micro-parent stock, characterized in that, to carry out said micropropagation: the explants are, under axenic conditions, in the dark and for a suitable period of time, placed on a proliferation medium which is composed to suit each plant species to be propagated, so as to induce the formation of white filaments which comprise axillary buds, each of the white filaments is divided into a plurality of pieces, each of 20 which comprises an axillary bud, and said pieces are, in the light, under axenic conditions and for a suitable period of time, placed into a rooting medium, which allows each axillary bud to produce a micro-plantlet which has roots.
