Yes. Though they can take a fairly deep frost if it is not for days.

Yes they do, in hard winters like 2010 / 11 even parsnips can be lost but that is rare. Hardiness here and maybe with you, is not so much about zones as rolls of the dice, I have known winters that killed conifers, and some when pelagoniums came through outside.

@Fernapple I agree. I have always found that Uk weather is so variable that you can have something which survives and even does well for years and then is suddenly killed off by an unusual event. With gobal warming we are told that extreme events will are likely to become more frequent, so forecasting weather that is already variable is going to become very difficult. The UK is not really big enough to have predictable zones like the USA.

We don't really have the hardiness zones here, they do not work so well in Britain, though mine is said to be on the border of 8 and 9.

That's interesting I really like to find out about growing in other parts of the world. Having usually mildish winters here, we also over winter some cabbages of course though I do not have any this year, we also grow sprouts, which I love, and I have a good stand in another part of the garden.

Nice, I love leeks in soup of any sort.

Some late Chrisanthemums, we grow them round the vegetables, in the perhaps vain hope, that they will keep pests, especially insects away.

@Fernapple hey! I grow lemongrass around my outdoor sitting area with Hope's it will keep mosquitoes away. ?

@Zoohome Mint cleared my side porch of mosquitoes .
