African Violets can be divided in four main categories depending upon their size: Large plants, Standard plants, Semi-Miniature plants, Miniature plants. The diameters of these African violet plants are measured across a single crown. They are each defined as below:
  • Large African Violet plants:

  • Large African violet plants when fully mature range from 16 inches (40cm) or larger in diameter across a single crown.
  • The flowers on these plants can grow to 3 inches (7.5cm) across the petals and a single leaf blade can grow to 6 inches (15cm) in length.

  1. I need help understanding when a grower gives a description of an african violet and they write the word : Large
    What are they referring to, the size of the plant when it is fully grown or it is a large standard plant. I seen some growers have written large standard that is why I am asking

    1. Hello Jessica, thank you for your question. When its large, they are referring to the size of the plant when fully grown. A large violet is larger than 16″. Regarding a large standard, I would assume its a standard size plant, but on the larger side, maybe 12-16 inches. A regular standard would be around 8-12 inches. Yes, it can get confusing, especially when sometimes the same plant can grow to different sizes, under different environmental conditions.

  2. Awhile back I purchased several African Violets in 2″ plastic pots from a plant nursery that I thought were miniatures (or so I was told). They are/were fully leaved and in bloom. Nine plants later and after several that expired I specifically asked the nursery if in fact, they were miniatures – and they weren’t (much to my disappointment). I was told they are simply very young plants. If they were true miniatures, I don’t think so many of them would have expired. They are so difficult to care for because I was sold baby blooming plants! Any suggestions on how to make these youngsters thrive?

    1. Hello Victoria, in the future, if the plantlets are small, I usually keep them in enclosed baggies for 4-6 weeks under lights or near a bright window (indirect light). Once they start new growth and seem healthy, I open up the bag, leave them inside for another week and then bring them out on the plant stand or window sill. I will then re-pot the plant, spring is a good time to do this, as it will quickly take to the new soil in warmer weather. Hope this helps, BV

    2. I have a whole collection of African Violets, both mininatures and standard size. I have some of the larger ones on a plant stand in self watering pots. The plant stand sits in a really large hard plastic saucer with rocks on the bottom. I keep water in the saucer for humidity. I also sit more violets on top of the rocks. The mininature violets I just have them sitting in a large saucers with the rocks and water. The all have bright light all day long. Mine have be blooming constantly and I’ve had the for a long time. Good luck.
