I've not come across any and I did look a couple of years ago. Toto is similar but I didn't find that they flowered at the same time. though Parkers claim toto is a white tete et tete.

They don't have to be multi-headed, just flower at the same time.

I think wp milner flowers about now and it is very pale.

Thanks Sbg - that's one I can add.

Thalia

N. Minnow is another and have you considered bi colours like N.canaliculatus, white petals with a golden yellow cup shaped crown.

Thanks Sbg. I'm not ruing out white and yellow ones. I'm just looking to plant one or two small clumps of something that will contrast with a predominant planting of Tete-a-tete.

probably not much help in the short term Andrew but have a look at this link http://www.srgc.org.uk/feature/ianyoung/nthybrids.html

Yes, Ian has a lot of interesting plants he has bred and is now trialing. Corydalis 'Craigton Clumper' is a good blue one that is now available from a few nurseries.

we went to Greenbank garden in Glasgow today. I spotted Mitzy a lovely dwarf daff. It is not pure white more creamy coloured but might interest you. I spoke to the gardener. They do not sell them but she thought they would be widely available in autumn. It is shown very well on Owdboggy's photos dated 4.3.10. When I googled it I came across this site. There are quite a few white narcissus - Elka, Fuko, Xit, Picoblanco, Pledge, Mitzy is there too. http://s409107849.websitehome.co.uk/acatalog/narcissus_d.html

Thanks SG - that could be just the job.

You are welcome
