This is a “must have” plant for any garden. It grows almost anywhere, flowers for ages and will seed itself happily around in places you couldn’t get it to grow if you tried!
Campanula poscharskyana is one of the lower growing members of the Campanula family however if it is growing by a wall it will lean its shoots up against the wall most effectively.Generally its about 6″ to 8″ tall and has mid blue bell-shaped flowers for many weeks in the early to mid summer. After flowering tidy up by just pulling out the long arms and then in a few weeks you’ll get a second flush of flowers. Bees and hover flies adore it, as I say , a “must have” plant!
