First attachment is of a show pansy called Blackfauld’s Gem.
(second attachment shows true colour)
The belt should be a complete one, as shown on the second attachment, but for a while (this was taken on 7th May this year)most of the belting colour was lost ,
Later blooms reverted back to the correct colours.
This happens on some Florist types, perhaps because they are very different to the ones sold in the Garden Centres, I suspect it has something to do with their aged genes, most are over fifty years old since they were introduced into cultivation.
Any further ideas appreciated.
