Delphiniums

[granadagirl]

Hi
Can anyone tell me why they’ve got from bright blue to this dirty colour?

Also what do I do with them after?

Thanks

The weather does affect some flowers, for example my ‘hot lips’ salvia changes to white or red depending if it’s hot or cold. My white Lychnis had now got a pink centre.
Delphiniums are perennial, but short lived, a couple of years if the slugs don’t get them first.
