Says on the pack that they tolerate cool weather, just wondering if they would tolerate an unheated greenhouse candle powered by night!!!
Cool perhaps, not cold,, I would treat then like any other, I think you will find it means the plants not the germination of the seeds or seedlings,I would be very wary of a claim for courgettes in "cool" weather. Cool compared to what..if they are US bred and most are it could mean anything.
