- Description and general information
- This bellflower grows among limestone and volcanic rocks and crevices at elevations up to 2300 m. It is found in Armenia, Turkey and the Caucasus.
- The plant arises from a thickened root and forms a tuft of decumbent stems up to 20 cm in length. The leaves are deep green, glossy and shaped like those of birch (hence the common name 'birch-leaved bellflower'). From pink-tinted buds open creamy-white flowers up to 3 cm in length. It disappears back to the rootstock in winter. Like so many Campanula, it is prone to slug damage. It is hardy through zone 5.
- This bellflower will tolerate full sun to part shade but demands a well-drained site. Too much winter-wet will kill the plant. It is adaptable to variable soil pH levels.
- Bloom period
- May in the south to July in the north.
- Seed and cuttings.
- Seed sown at 20 C will germinate within 3 months. Seeds stratified for 8 weeks will also germinate freely. It is also known to self-seed in the garden.
- As the plants arise from a thick rootstock, division is not generally practiced.
- Young shoots may be taken as cuttings prior to their producing flower buds. They generally roots in a few weeks.
