What could have happened to these leaves?

Hi guys,
I noticed today that my Delphiniums and some aquilegia have strange things going on around the edge of the leaves? Does anyone know what it could be? We haven't had any frosts lately.
Thanks

We have not had frost but this mild spell was followed by strong winds & wet. The soft growth could just have been "burnt" by the wind.
Burnt by the wind? I never knew that could happen. How does wind burn plants?
New leaves are very soft and moist and haven't yet 'hardened off'. The wind causes bruising and rapid evaporation of transpired water and can cause excessive dryness especially at the leaf tips. Not really 'burning', but the leaves can look scorched.
Don't worry, your plants should recover, but a little shelter from some fleece or similar would help, if they are in an exposed spot.

Yes sorry its just a term that gets used because that is what it can look like. Its as explained above. This is why plants raised in a greenhouse or indoors need to be "hardened off"- basically gradually introduced to colder more exposed conditions. A very mild spell followed by cold winds as we have just had can cause the same problem.
