Will they, won't they?

Trev gathered these sweetpeas to take to a neighbour but I'd got them into a vase before I realised so he hd to pick some more. They were grown in the green house and we have lots in pots outside. They are all intended for Tam and Jim's wedding on 25th and the question is ...will the ones in the greenhouse be over too soon? Come to that...will the ones outside be ready in time?
