Lancashire, United Kingdom
This is 2 questions in 1. I am cutting back my Knautia Macedonica Melton Pastels and wondering what I can put in their place, as I have a big gap in my border. And my second question is how can I stop them from toppling over when they are in bloom. I have staked them with one of the metal stakes this year but to no avail.
