GLYCERINIZING FLOWERS,FOLIAGE AND LIMBS
To glycerinize plants for long term preservation, combine 1 part glycerin with two parts warm water. Immerse stems stripped of foliage. Place plants in a cool, dark location. Add further solution if needed, until plants stop absorbing the liquid.
Glycerined plant material will be more pliable. However, not all plants can be glycerined.
Glycerinized plant material may mold readily during high humidity conditions. Store accordingly.
