Zone 5 do you have any campanula rapunculoides?
I saw these in my sister in laws garden and thought they were very pretty swaying in the breeze. I asked what they were but she did not know.
After researching and finding out what they are, they seem to be invasive in some areas.
My question is...do you have them in zone 5, and is it invasive for you? I'd really like to plant these, but surely not if will be a headache (and backache) later on. I'd also like to warn her if so.
