So muh depends upon the amount of frost we get - until 2 years ago I left alot of things outside but after that killer winter I bring into the greenhouse alot more than I used to do. Alliums are fine out there, as are lilies, but blue salvias, chocolate cosmos (not the annuals) need bringing in, as do geraniums, not the scrambers, they stay out and are fine, but the pelargoniums. Fuschias, some potted pinks, agapanthus in pots, various other tender things come in when the night temeratures drop enough for a grass frost. I keep the greenhouse around 5 degrees when it freezes, with an electric heater. Anything that needs more than that just has to take its chances.
