Quite a few snowdrops sometimes throw extra petals from behind the receptacle (ovary) but are not usually consistent from one year to the next. As you probably know, the snowdrop formerly known as 'Atkinsii' but now split-off to become 'James Backhouse' does this quite frequently, as well as tending to produce extra outer petals in their normal location. You need to keep your one under observation for a few years.
Allan, thank you for the explanation. I will keep an eye on it for the next years.
