Campanula portenschlagiana

Plant details

Hardy, vigorous and persistent, Campanula portenschlagiana is an alpine campanula, easily grown in rock gardens, on walls, in front of borders or even in continers. It forms a generous, dense mat of small ivy-like leaves which become hidden beneath the mass of small purple bells in summer.

For best results grow Campanula portenschlagiana in well-draind soil in full sun. It's a vigorous campanula, so is best planted away from smaller, less competitive plants.

Easy to grow, intense colour, flowers from early May through to September in my garden (if good weather prevails). Divides easily. I have it in pots with Hardy Geraniums, as edging in drier places and small clumps between flagstones.
An excellent companion to all other plants.

Fantastic easy plant that generously gives in colour like almost nothing else. A thousand and one uses for some of the most interesting areas in a garden. A nice blue cool purple that literally goes with everything. Clouds of colour down walls out of pots darkish corners as a ground cover in well drained areas.

I found this plant is not as persistent for me as I would like but it's easy replaced. It seems to do very well for three maybe four years getting pretty large, then vanish, often self seeding to another spot meantime.

I dont think any garden should be without it, if nothing else have a big pot of this and be amazed at the sudden burst of colour.
