Wildflower disease

Hi there, some of my wildflowers have started to develop what I assume is a disease.
The stems have started to turn brown/purple and the leaves have begun to shrivel and turn red/brown.

Please could anybody help me identify this and advise what to do?

Thanks in advance!

 

What are they?
Just think the purple stems is part of the ageing process.

 

Hi Pete, thanks for your reply. I bought a pack of wildflowers seeds so I'm not sure exactly what flower they are yet until they bloom.
The leaves look a bit diseased to me? They're wrinkled, dry and going red around the edges. Could this also just be the ageing process?

 

Difficult to say really, might be some aphid on the backs of the leaves.
Wild flowers are usually pretty tough and go on to flower.
That's not to say they will always look pristine.

 

Thanks a lot, really appreciate your help!
