Large flowered Bellflower
Campanula latifolia var. macrantha 'Alba'
A stately plant of distinction, Campanula latifolia var. macrantha 'Alba' is an outstanding plant for the border with tall upright stems bearing large, pure white, trumpet-shaped blooms in summer.
It looks good towards the back of a border, in sun or partial shade, and works particularly well in cottage garden style planting, grouped or en-masse for best effect.
Growing to a height of 38-40" , with a spread of 16 ", it is easily grown in any fertile soil in sun or light shade. Flowering from June right through to August, the large elegant white blooms are around 2" in length and show up particularly well against its dark green leaves.
Campanula latifolia is a very hardy plant and can withstand temperatures down to minus -31°F, it is also one of the most adaptable. It is a good plant for a wild or woodland garden or for naturalising in dry shade under trees. It can be used in a cottage garden scheme, in garden borders or on the terrace. The flowers are at their best when placed in a position where it will receive at least a few hours of sunlight each day.

How to Grow:
Sowing: Sow in either late winter/late spring or late summer/autumn.
Sow either in September to October before the coldest part of the year or in February to April and plant out after all danger of frost has passed.
Sow the seeds into cells or pots containing good quality seed compost. Sow finely onto the surface and press lightly into the compost, but do not cover, as light aids germination of seeds. Place in a propagator or cover with a plastic lid and place in a warm place, ideally at 65 to 68°F.
Water from the base of the tray, keeping the compost moist but not wet at all times. Germination 14 to 28 days. Once some of the seeds have germinated air should be admitted gradually otherwise the seedlings may suffer damping off.
Transplanting:
Once the seedlings have their first pair of true leaves (they come after the seedlings first pair of leaves) and are large enough to handle, Prick out each seedling into 3in pots to grow on. Place in a position which receives diffused light.
Gradually acclimatise to outdoor conditions for 10 to 15 days before planting out after all risk of frost has passed into well drained soil. Plant 12in apart
The ideal situation is in partial shade or sun, in fertile, neutral to alkaline soil that is moist but well-drained.
Cultivation:
Protect the tender foliage from slugs and deadhead regularly. Bellflowers like some relief from intense sun and heat a dry summer may reduce or inhibit its flowering. If your garden is in full sun, apply a generous 2-3in mulch of well-rotted compost around the base of the plant in spring and keep them well watered.
In exposed areas, stake with bamboo canes or brushwood in spring before the flowers appear.
Deadhead to prolong flowering. C. latifolia will self seed if not deadheaded, but are not a nuisance like some campanulas. They are easily curtailed after blooming as the blossoms are long gone before seed is set.
Harvest:
Cut stems that have one-quarter to one-third of the flowers open
Pruning: Cut back after flowering to prevent self-seeding and to encourage a second flush of flowers.
Vase Life: 7 days or more
