Campanula medium

Campanula medium, common name Canterbury bells, is an annual or biennial flowering plant of the genus Campanula, belonging to the family Campanulaceae. In floriography, it represents gratitude, or faith and constancy.

Etymology

The specific epithet medium means that this plant has intermediate characteristics in respect of other species of the genus Campanula. In Persian, it is called گل استکانی (gol-e estekani) meaning "glass flower", because the flower resembles a drinking glass.

Description

Close-up on a flower of Campanula medium

Campanula medium reaches approximately 60–80 cm (24–31 in) in height. This biennial herbaceous plant forms rosettes of leaves in the first year, stems and flowers in the second one. The stem is erect, robust, reddish-brown and bristly hairy. The basal leaves are stalked and lanceolate to elliptical and 12–15 cm (5–6 in) long with serrated leaf edge. The upper leaves are smaller, lanceolate and sessile, almost embracing the stem.

The flowers are arranged in a racemose inflorescence of extremely long-lasting blooms. These attractive bell-shaped flowers are short-stalked, large and hermaphroditic, with different shades of violet-blue or rarely white. The corolla has five fused petals with lightly bent lobes (known as a coronate flower type).

The flowering period extends from May to July in the Northern Hemisphere. The flowers are either self-fertilized (autogamy) or pollinated by insects such as bees and butterflies (entomogamy).[1] The seeds ripen from August to September and are dispersed by gravity alone (barochory).

Distribution

Campanula medium originates in southern Europe. It is naturalized in most of European countries and in North America and it is widely cultivated for its beautiful flowers.

Habitat

It grows on stony, rocky and bushy slopes, at an altitude of 0–1,500 metres (0–4,921 ft) above sea level.

Gardening

In gardens, they are best in massed planting in borders or among shrubs. It prefers cool or warm zones; not suitable for the tropics or hot, dry regions. Seeds take 14–21 days to germinate. The plant thrives in lightly shaded to sunny locations in well-drained soil. Canterbury bells grows nicely in flower beds, borders, and containers. Keep well watered.
