Living plants, in particular coniferous plants, with the exception of Picea, Abies, Tsuga, Larix, Taxus and Cedrus genuses, are preserved by having them suck up a preservative liquid which is based on glycerin and water in volume proportions of 18:82 to 35:65 and contains dyestuffs for replacing the color of the plant parts after preservation. The dyestuffs are to comprise, apart from a blue and possibly also a red dyestuff, tartrazine (C.I. 19140, E102) in a concentration of from 2-10 g/l of preservative liquid. The blue dyestuff comprises preferably patent blue V (C.I. 42051, E131) in a concentration of from 0.1 to 0.8 g/l and the red dyestuff most preferably of new coccine (C.I. 16255, E124) in a concentration of from 1 to 20 g/l. The relative concentrations between the different dyestuffs are adapted into conformity with the sought-for color of the preserved plant. The preservative liquid may advantageously also contain a water-soluble potassium salt, preferably potassium nitrate in a concentration of from 1 to 15 g/l. The preservation is effected at a temperature of from 15 DEG to 33 DEG C. in a current of air at a relative humidity of at most 60%, the preservative liquid preferably being a few degrees centigrade warmer than the current of air.
