White back? That's interesting. May be light green? Can you post a pic?

If you are dealing with a variegated leaf - that has white or pink areas on the leaves - the leaves on the babies will be variable too. If it is a light green leaf plant - and the babies come with different shades of leaves - it is probably a mutation - and the blossoms of the babies with light green leaves and with dark leaves can differ too. Happens when you have multicolor flower - fantasy or edge or chimera - and usually the dark leaved ones will bloom with a single dark color. You can raise them all to the first bloom - and decide which are the best - and which are not worth keeping.

Thanks for your response. I meant light green back on the leaf. As far as I know, it is not from a variegated violet. I'll keep some of each and see what I get! :-)
