Orris Root Powder
Making your own orris root powder to use as a fixative in potpourri or other crafts is easier than you might think. Orris powder is made from the rhizome of the Iris x germanica var florentina, often referred to as orris iris. The pale lavender flowers appear almost white.Once this iris is established, the rhizomes multiply rather quickly. Allow the plants to grow until they are beginning to get crowded, then begin to harvest what you want. Some people remove their iris rhizomes from the ground and divide them that way. I leave mine in the ground and use a sharp knife or clean pruners to slice through the rhizome removing only the ones I wish to harvest. Once I am back inside, I cut off all the roots and foliage. This discarded material goes into the compost pile where it will break down. I then wash off the rhizomes to remove any dirt remaining on the rhizome. I pat the rhizome dry with paper towels, then put it on a cutting board and slice it into thin strips. Some people prefer to grate the rhizome because that gives you smaller chips that are easier to powder.
