Campanula

Common name: Bellflower

Campanula carpatica: takes its name campanula from the Latin translation for little bell.

There are literally hundreds of species and sub species of this plant found throughout the temperate regions of northern hemisphere.

These species are further split into either, annual, biennial or perennial plants.

They can vary dramatically in height i.e. from the 50mm (2") high alpine species to the 600mm (24" high meadowland species.

The UK National Collection of Campanulas is held at Burton Agnes Hall in East Yorkshire, and the National alpine collection is at Langham Hall in Suffolk.

The aptly named carpatica is a very popular semi-deciduous perennial that is suited to growing in borders and rockeries.

The 25mm (1") wide cup-shaped flowers in varying shades of blue and purple appear in July and August.

It forms 300mm (12") clumps and spreads to around 450mm (15") across.

Remove faded flower to prolong the flowering period.

They require well drained fertile soil in either sun or partial shade.

Cultivation:

Week 12: Sow seeds in pots / trays of seed compost, and place in a cold frame or cool greenhouse.

Germination can take up to two weeks.

Week 17: When large enough to handle, prick off the seedlings into 75mm (3") pots of potting compost.

Grow on in coldframe until they are ready for planting out in September.

Week 18: Take tip cuttings.

Select short, sturdy un-flowered shoots and trim just under a leaf joint with a sharp knife.

Insert around the edge of a pot filled with a sandy compost and root in a propagator or clear plastic bag indoors.

Once rooted, pot up into 75mm (3”) pots and grow on in a frost-free greenhouse until planting out time.

Week 35: Plant out plants 300mm (12") apart, any time from now until April.

Week 40: Large plants can be divided and replanted immediately.
