Random plant event: mutant Platycodon?

Not only does this Platycodon flower have three more petals than usual, but it's tagged Platycodon 'Fuji White' besides. The tag could be a mistake (tags do get switched around, and dropped, and so forth), but the petal thing is absolutely the plant's own idea.


I've seen a couple plants try for ten petals, here and there, though that's less surprising. I already knew that sometimes plants double their petal count (usually because they've doubled chromosome number). But this is different.

Actually, do these even count as petals, exactly? I mean, they're all fused together, right? So is it normally five petals, or one really big petal? Is there a botanist in the house?
