Perennial herbs are usually reproduced by stem cuttings, either softwood cuttings of immature growth, or hardwood cuttings where the bark has been scraped to expose the cambium layer. A cutting will usually be approximately 3 to 4 inches in length. Plant roots can grow from the stems. Leaves are stripped from the lower portion up to one half before the cutting is placed in growth medium or rooted in a glass of water. This process requires high humidity in the environment, sufficient light, and root zone heat.
