I think its a nerine, sometimes called a guernsey lily

Mine are in pots in the gh

Thank you for that. We saw them in a front garden when we were out walking and they looked really pretty. I have found that our local nursery sells them, so off I go tomorrow to get some.

You should be fine where you live, we're on a windy hill in the midlands and have cold wet clay soil so growing them in clay pots in the gh means I can have lovely flowers at this time of year, I got the idea after going to the nerine festival in guernsey.....they had such lovely ones, different colours all in clay pots

When I saw them in that garden, I thought that they were the same as some flowers we had seen when we were on holiday in Lymington in November a couple of years ago. I looked through all the photos I had taken and there it was - the same flower, in a beautiful garden at Exbury, near Beaulieu. They were being grown in greenhouses too, and I was very tempted to buy one or two.
Even though it is going cold, we must be slightly warmer in the Isle of Wight for them to bloom so nicely.Thank you for your help in naming them.

If you don't know this lovely bulb its good to remember that they flower this time of year without the leaves, and the leaves appear without the flowers earlier in the year, so until you get used to where you've planted them its a good idea to mark the spot. They have thin strappy leaves rather like narcissus but brighter green.

thanks for the info Steragram. That will prevent me pulling up the leave thinking that they were not going to bloom.
