Hi Lucky,

I'm afraid there is no Viola named 'Delpht' - I have a copy of the RHS Plantfinder from 10 years ago (which also covers the previous 5 years) and there was not then, nor is there now any Viola of that name grown by any UK nursery. The only Viola with a similar name is 'Delphine' - which is shown on the webpage below:

Thank you for your searching and surprised at the outcome.
My sister in law remembers a large and beautiful display at a garden centre so it seems she may have seen another white plant with blue edge.
Could it be a pansy? Is there anything called "delpht"?

Hmmm....there is a fairly well known Pansy named 'Delft' - the lower three petals are creamy yellow with a little fine whiskering while the upper two petals are blue with a creamy edge - which doesn't sound much like your sister-in-law's plant unfortunately!

Thanks again . This could be it... although I couldnt find any pictures of Pansy "Delpht"
I will ask her if she has forgotten the actual colour as it was some years ago her original plant died.

Lucky - the Pansy is named 'Delft' rather than 'Delpht' :)

Thanks again
I have looked under " Delft" but we get pictures of the pottery and lots of other things but not a picture of the actual" Pansy Delft"
My sister- in- law seems certain it wasn't spelt as in the pottery "delft" but as it was so long ago she may not remember correctly.
I think if I could find a good picture of the Pansy "Delft" you say is fairly well known it may remind her...but all the usual plant sellers don't appear to stock it under that name.

Lucky - I think the Pansy 'Delft' is a Thompson & Morgan plant so may be available via them
