I have three of them that I bought two years ago. I think. They're very pretty and have stayed variegated. They're quite short so you'll need to stick them somewhere you can see them. They flower well for me. Mine have sort of a wine red bloom. My only complaint is that I'd wish they'd grow a bit more vigorously as they're so pretty.

Thanks for the post athenainwi. So you do gets lots of blooms per plant...good to hear. How long in the spring? or summer does this particular 'Knautia' continue to bloom?

By chance do you have any photos of your 3 plants in flower?

I'll see if I can find pictures. I seem to recall them flowering in June and July but I don't remember if it was the whole month.

generally, variagated plants do lack some vigour - which can be a positive thing (aegopodium for example).

I have seen this older stock of this plant in a couple of nurseries and the base leaves of many are non variegated. So it does seem to revert.

My experience with Knautia macedonica is that it blooms all summer long, but not many flowers at any time. Besides, it is not very long lived in my experience.

i have lost this fantastic bold foliage plant 3 different yrs. But trying again. Flowers are def not pink, rather crimson/burgundyish. just starting to flower now; use it on bed edge as it keeps very tidy.
