METHOD OF PRESERVING PLANT MATERIAL ABSTRACT OF THE DISCLOSURE A method for preserving cut plant material comprising immersing, within a pressure vessel, the particular material in a treatment agent constituted of glycerin, ethylene glycol, diethylene glycol, triethylene glycol or mixtures thereof; said treatment agent having a specific gravity within the range of 1.10 and 1.16; there being a suitable dye provided with said agent. The immersed material is subjected to an applied pressure greater than atmospheric, as within the range of 5 to 40 psi; but under ambient temperature and humidity; the material being maintained under such pressure for a pre- determined period dependent upon the applied pressure for absorption of the agent and dye. The material is then washed and thereafter permitted to be dry under room conditions.
