Just acquired my first violet and having trouble identifying the type I have (see attached photo). It has variegated leaves and the grower told me it was a "Portuguese violet", but I can't find any info on internet for that kind. Is this just another name for sweet violets, or do I have something unusual here? Please help since a little more info will assure I give this beauty the proper care. Any assistance to figure out the variety I have would be grately appreciated...
