Please don't post in capitals it is known as 'shouting' makes it difficult to read your question!

I can read your question Paula. welcome to GOY Sorry i don't know what's happened to your petunias but they sound lovely. do you have any photos ?

Hi Paula welcome from me too - your Petunias are lovely the colours such as the blue ones are quite striking. You will soon get use to the site and its idiosyncrasies! Its very friendly and very gardening focused which is why I love it.

It looks to me like you have two or more different plants in the same pot. It offten happens at the grower when they start several seeds to a cell--to ensure getting at least one healthy seedling--and then don't thin them out later. The main stems wind up so close together, you need a magnifying glass to see that they aren't just one! No one knows until the second (or third) plant flowers. It saves them labor, but causes us gardeners confusion. Normally no harm to it, but sometimes one or two plants will suddenly wilt and die. because of the competition.

Agree with Tugbrethil.

That's exactly what I said on one of the photos! Glad we agree.
