Have never had any desire to own Mini Purple .... because of the scent. Very nice flower on a small plant but they have a unpleasant chemical scent to my nose. Unfortunate for me as I always gravitate towards minis and there aren't many minis with such a nice purple flower.
I don't own a mini purple, but I do have a few crosses with it's parents. They definitely have a chemical scent that gives way to something pleasant. Sometimes it reminds me of moth balls with overtones of floral and vanilla.
