These are attractive and hardy perennials in my zone, dying back to the soil in winter and regrowing every spring. They readily self-seed and spread, but I wouldn't call them invasive - unwanted plants are easily removed. I have both white and blue varieties, which appear to have naturally hybridized and produced a pale blue variety. Mine thrive in an east exposure with morning sun and afternoon shade.

I planted three of these in a basically sunny well drained area and have watered them regularly. The blooms there when I bought the plants were beautiful; but since they died I notice the entire stalk dying. I have tried topping the dead growth; but there is no regeneration. Loved it when in bloom; can't figure out what to do or what went wrong.

I am a beginner gardener and this is definitely a good plant for beginners. I purchased a bellflower plant from a local nursery and planted it in a location that receives full sun. Within 10 days, there were about 6 flowers had bloomed. It bloomed all summer long and was even blooming in October. Definitely an easy care plant since mine hasn't required constant watering.
I'm planning on adding more of these to our yard this year since they're so pretty and easy to take care of.

Large bell shaped flowers on wiry stems with attractive foliage. They do spread quite a bit, although I have not found them invasive. Especially nice used at the base of daylilies or other tall plants.

This campanula is a low grower and forms a 1-2 feet wide clump of heart shaped leaves. Its thin, wiry stems produce upturned, bell-shaped flowers for many weeks in summer. Colors range from white to deep purple. It prefers a fertile soil in sun or partial shade.
