My friend found a piece of info once that the flower for March was an African Violet. So far, that was the only time she has seen that and has been unable to confirm it since. We have found one reference to a Jonquil. Are African Violets an alternate March Flower and if not what month if any do they represent?
Did the piece/book actually say African violet? Perhaps it confused it with the common violet,Viola odorata which blooms early in the Spring.

this link confirms more or less your friend’s claim.

this one doesn’t.
Most sites I looked at seem to have the daffodil as the flower for March.
