Campanula carpatica originates from the mountains of the Karpaten and is grown more and more in gardens and in the wild in the Netherlands and Belgium. The large, striking and unusual bell-shaped flowers are on thin fragile green stems and are surrounded by thin, feather-like, fresh green leaves. This mixture contains blue and white flowers and is very well suited for the permanent border, as a rim to surround a border, as ground cover and as eye-catcher or in groups in any garden. This very long flowering plant looses a portion of it's leaves in the winter. Hardy perennial. Height: 10 - 15 cm.

Sow indoors from march in large pots or in a cold frame. Sow thinly and shallow and press the seeds gently in the soil. Campanula carpatica is a light germinator. It can take a long time before the seeds germinate. Keep moist and have patience. Keep the temperature during the germination as even as possible. Don't let the temperature drop during the nights. Harden the seedlings in the beginning of may of for about 10-14 days. Plant them outdoors after this period on a sunny, sheltered plot with some shade and free draining soil.
Sow outdoors from may on. Sow thinly and shallow and press the seeds gently in the soil. Thin the seedlings, when they're large enough to handle to about 10 - 15 cm apart. Keep moist and weedfree. Campanula carpatica will reseed itself and is very well suited for a wild garden.
