Solanum cf. evolvulifolium

I’ve had this plant for a few years now and up until now, it has been putting out mostly purple leaves with pale leaf venation.  It’s overall appearance isn’t that exciting.  This month, however, I was shocked to see an entirely different looking leaf on this species, which looked so unalike the typical growth I thought it was a hitchhiker that I was just now noticing.  It has bright green leaf venation and leaf tips.  Had I not checked to see the older growth on this particular plant, I would not have thought it to be the same species.  Unfortunately, I think this growth pattern is limited to new growth, but, one can hope!  It seems to be a response to osmocote slow release fertilizer added earlier this month.
