Certain varieties of perennials can be used to create new plants. This is accomplished by the use of various propagation methods. The general methods used include cuttings, division of old clumps, propagation from leaves, and budding. Some varieties can be propagated by a number of methods; for others, only one way works.
Cutting is the process of removing a small portion of a growing plant and treating it so that roots are developed. The cutting can then be transplanted and will, in time, produce its own blooms. Cuttings are usually made from a portion of the stem, from leaves, from tubers or from roots. Cuttings are usually rooted in a mixture of sand and peat moss. Some varieties can be induced to root in water, in sphagnum moss, or in light, sandy soil.
