Available in many flower colors, they produce flowers year-round under the proper growing conditions. Individual flower clusters may last three to six weeks under good conditions. Double or semi-double rows of flower petals are available on many of the newer varieties. Bicolored flowers and those with contrasting borders are also popular. Minatures and trailing cultivars are also available.
African violets require a soil mix that is well-drained.
Commercially prepared packaged soil mixtures are available for African violets. Clay or plastic containers are both satisfactory, but the type of container has an important effect on the frequency of watering. Clay pots require more frequent watering than plastic since the amount of evaporation is greater. Decorative glazed pots without drainage holes should not be used due to the lack of drainage. Sterilized soil and containers are important.
