Brunnera macrophylla 'Jack Frost'

My Brunnera has developed many black, dry leaves  which eventually drop off and is looking decidedly unwell. I am worried I will lose the whole plant. The one next to it seems unaffected. Any suggestions?

    Have you got a photo?
    They're generally pretty trouble free, so it may be as simple as the damaged one being dry.  :)

    They tend to die back a bit during the summer here, then regrow when it turns cooler and damper. I think it's just a response to hot dry conditions after they've done their flowering for the year.

    Did you cut them back after flowering?

    I usually shear brunnera leaves right back when they start to look tatty (beginning of July). With a bit of water fresh growth appears within a couple of weeks and they look good for the rest of the season.

    I do the same as Topbird … cut them hard back and give them a bucket of water. They soon look fine again.

Apologies for pinching your thread!

    Mum used to cut mine when |I was little and I hated how it looked. In all my adult life I've only ever had it cut twice.  It doesn't get any longer now I'm 27 :)
