Platycodon ballon flower
Ballon flower platycodon had purple leaves last year. Just started coming up out of dormancy
I cut it down as soon as the purple leaves got worse and put the leaves in the bin.
I'm not sure what you are asking. Like hibiscus, balloon flower is typically late to emerge in spring. If your question is that the leaves turned purple last year and it wasn't due to cold weather, it may have had Botrytis, gray mold or another fungal infection. Inspect the leaves as they emerge and if you see disfigured leaves, send a detailed description or a picture and we'll try to ID the problem. I wouldn't treat the plant with an anti-fungal unless you see early evidence of leaf disease.
