My favorite campanula. I start a flat every year, so I always have some in my garden. Takes two full years to bloom. Mine stay one year after the first bloom, but do not bloom heavily the second year.

In a hot climate the flowers turn white but otherwise the plant doesn't seem to be ill affected by the heat and dryness of my zone 9/15.

This has to be one of my favorite plants. It is beautiful . It bloomed all summer, it is now October and still blooming! I don't even know where it came from. The first year it was just green leaves, this year it hasn't stopped blooming since it started. It is said it will now die off after a year of blooms. I hope it has reseaded itself well. Maybe a little mulch will help it stay around another year.

From Greece, this biennial bellflower is well worth growing. Plants are quite busy and produce many lavender-blue 'chubby' bells. Allow them to self-seed to carry on the display for the future. Good for the rockery or front of the pernnial border. Overall, it looks like a dwarf canterbury bell, C. medium.
