Miniature roses are beautiful and tiny versions of a normal-sized rose bush. These small flowers range from 3 to18 inches tall. Because all miniature roses are descended from one Chinese dwarf rose named "Rouletii," they unfortunately have no fragrance, according to the University of Illinois. Still, these delicate-looking but very hardy flowers are popular with home gardeners and are especially attractive when planted in a container. With proper care, miniature roses thrive indoors.
Plant the miniature roses in 4- or 6-inch pots with a well-draining potting medium such as peat moss.
Place the miniature rose in a bright, sunny location for eight to 12 hours per day or under grow lights for 12 to 16 hours per day.
Keep the soil evenly moist while the rose is flowering but not overly soggy or the plant could suffer from root rot. Never let water stand on the surface of the soil or in the container's tray. Allow the soil to dry out between waterings when the rose enters its dormant period in late fall. Cut it back to about one-third of its height.
Fertilize the rose weekly from spring through the summer with a water-soluble fertilizer high in potassium. Apply only one-quarter of the recommended amount.
Rinse the miniature rose bush once a week or so with an insecticidal soap.
