ABSTRACT:
A plant material is preserved by immersing a cross sectional surface of a severed stem, stalk, trunk or vine of a plant material into a preservative solution. The preservative solution can include a suitable dye. The plant material remains intertwined with its trellis, lattice or similar support during a preservation process. Alternatively, the plant material remains in a natural configuration during the preservation process. Also alternatively, the plant material also remains in a natural orientation during the preservation process. The cut stem, stalk, trunk or vine can be immersed in a container of preservative solution, at or near the time the stem, stalk, trunk or vine is severed. The cut stem stalk, trunk or vine of the plant can also be tied to a container of preservative solution. A rain shroud can also be placed over the container of preservative solution that contains the severed stem, stalk, trunk or vine of the severed plant, to protect the preservative solution during the preservation process. The rain shroud prevents the dilution of the preservative and the dyes by rain and the fouling of the solution by dust and debris. The preserved plant material can be a vine, including leaves, stalk, stem, flowers, cones, seeds and/or fruit. A preserved plant material can also be a hop plant, or portions of a hop plant, of the genus and species Humulus lupulus.
