Question: How long do African violets bloom?
Answer: This all depends upon environment, the variety being grown, and your care. Individual blooms can last anywhere from a few days to a few weeks. Varieties producing thicker petals and those with green in the bloom tend to last longer. Blooms will last longer under moderate to high humidity with cooler temperatures (say 60-75f degrees). With cooler temperatures, blooms will also tend to be larger and colors more intense. Once blooms fade or become “spent”, remove them, since their decay would likely shorten the life of adjacent blooms.
As for how long and African violet will have at least some bloom (the length of the blooming “cyle”, so to speak), this will also depend greatly upon the environment, care, and variety. Given a good environmen, and with proper care, most modern hybrids can be kept in almost continual bloom, once they mature. Most importantly, your violet will need good, consistent, light. This is hard to achieve growing in windows, since the amount of natural light the plant receives varies so greatly from season to season and window to window. Under artificial light, which can be controlled, African violets can bloom nearly constantly with proper care.
