This is a big family of widely varying perennials. I have not started to explore them seriously yet; others than sowing some seeds for fillers and a few chance acquisitions. Part of the reason is, of the few I have tried, some of them are very aggressive runners or seeders. As a country gardener, I need to optimize my time spent doing ‘control chores’. What I need is to spend some effort identifying the well behaved tribes.
The identities of the ampanulas I described here may or may not be correct (since I was not particularly diligent in tracking them).
Campanula ‘Dickson’s Gold’
A beautiful compact ground cover plant.
Campanula ‘Pink Octopus’
An interesting and pretty bell flower. It likes to run wild with runners. I tried to keep it in a buried pot since I like it enough not to remove it from my garden.
It is dainty and flowers very well, but it seeded around so badly I destroyed it.
I sowed this from seed many years ago to use it as a filler. It is invasive with runners. I am trying to control it by limiting it to certain beds as a filler.
