Water: Keep soil evenly moist, but never soggy. Use room-temperature water, and avoid splashing water on the leaves. To minimize the dangers of overwatering or underwatering, use a self-watering device.
Fertilizer: Use Optimara Violet Food 14-12-14, each time you water.
Light: EverFloris Violets, like all African Violets, perform best when they receive plenty of indirect sunlight. This can be achieved with sheer curtains or partially closed blinds.
Climate: Keep temperature at 60 to 80 degrees F. Ideal temperature is about 70 degrees. Humidity should be at least 40 to 60 percent.

In 1984, Optimara launched 25,000 Optimara seeds into space aboard one of NASA’s space shuttles. The seeds remained in space, orbiting the Earth, for nearly six years. The program was conceived to test the effect of long-term exposure to cosmic radiation and lack of gravity. When the seeds were retrieved in 1990, many mutations soon became apparent. One such mutation resulted in a new characteristic which Optimara has dubbed ‘multiflorescence.’ This characteristic gives Optimara Violets an extraordinary abundance of flowers which never stop blooming. Compared with PMA standards, which define a finished African Violet as having five to seven open blooms, a multiflorescent Optimara variety will have at least 20 open blooms.
Multiflorescence is just one of the characteristics that make EverFloris Violets so unique. In addition to larger, fuller blooms that flower continuously, EverFloris varieties have been developed to grow bigger. Overall, they are as much as 50 percent bigger. To accommodate their larger growing size, EverFloris Violets are cultivated in a 6-inch pot (instead of the standard 4-inch pot).
