The Campanula persicifolia ‘Alba’ is a member of the bellflower (Campanulaceae) family and is commonly named peach-leaved bellflower. The peach-leaved bellflower is native to Europe and the north and west of Asia.
The name Campanula persicifolia originates from Latin where campanulata means ‘bell shaped’ and persicifolia ‘leaves like the peach’. Alba means white.
This perennial will start flowering in the second year. The first year the peach-leaved bellflower will grow leaves and reach a height of about 10 inches (25 cm). It will spread through rhizomes but is not at all invasive. In the second year it will start blooming. The flower stems can reach a height of about 3 feet 3 inches (1 m) and are pretty sturdy. With heavy rain especially combined with much wind the stems may need some support. In August there is a second modest bloom also if you do not remove the spent flowers.
After bloom the seeds will develop. It spreads through the seeds but is not invasive. I always cut the stems with the ripened seeds and throw them where I want the Campanula persicifolia ‘Alba’ to grow. They never let me down.
In mild winters the peach-leaved bellflower is evergreen and in hot summer climates it likes some protection against the sun in the summer. The Campanula persicifolia ‘Alba’ is drought and salt tolerant but not to too much moist.
The flowers of the Campanula persicifolia ‘Alba’ often appear at the end of May in my garden and are perfect cut flowers.
