Confused

[Small pumpkin]

I thought sweet William was biannual? I don’t mean biannual do I ? They’re perennial aren’t they but don’t flower till their second year? I only sowed these seed this year.
I’m not complaining it lovely, just confused.

They are officially bi annual but I have kept them going for several years. As they get older the flowers get smaller until they are not worth keeping any longer.
