Bellflower is also called
Campanula, whatever kind of flower garden you have; there is a bellflower for
you. The flowers vary considerably in shape and size; though most are blue
colors, however some are violet or purple, and some are white. They are
extremely beautiful in pastel gardens, with roses, or just anywhere you want to
a blue accent. Some grow on plants of mid- border height, others on low
cushions, and others on long, trailing stems. Most bloom in early summer, but
some, especially the low growing varieties will continue to flower, though less
heavily, throughout the season.
Campanula persicifolia
“Grandiflora”, the popular peach leaved bellflower, is available in blue
varieties such as “Telham Beauty” and a white one “Alba”. It grows almost two
to three feet tall. C. glomerata also grows up to two feet; its variety
“Superba” is a wonderful rich purple, “Crown of Snow” is white. Moreover low
growing bellflowers include C. carpatica, blue or white, six to 10 inches and
C. poscharskyana, lavender, 12 inches tall but sprawling C. rotundifolia is
blue and one to two feet, but he variety “Olympica” is more compact. This last
species can be eddy in some gardens.
Well, if you really like to grow
this beautiful bellflower, then the plant like sun but will do well in light
shade, particularly in hot climates. Also give some moist, moderately fertile,
well-drained soil. Sometimes slug control may be necessary. Weed out the
invasive types as needed; cut back tall varieties after flowering to encourage
them to bloom again. Source: Charismatic Planet
