East Sussex, England
As you can see on my Helenium lemon queen (about 10 years old) and a Penstemon (about 5 years old). I have a problem in the centre of each which I only discovered today when cutting them back, they have flowered well and looked in good health all summer.
Is it due to the wet weather?
Will the plants recover or should I get rid?
