Despite having an almost completely unpronounceable name, Campanula poscharskyana is a very attractive and valuable plant for the rock garden. It is a vigorous, low-growing plant with long, trailing stems bearing finely toothed, rounded or heart-shaped leaves. The plants do have a tendency to become rampant, but, fortunately, they are not too difficult to cut back.

This species of campanula makes a very good ground cover plant, especially in areas where it can spread at will. If planted among low growing shrubs, it is likely to clamber up through the lower branches. It can be grown in a rock garden, but it will need checking to make sure that it does not smother its neighbours.

Plant out in the autumn, or in spring, whenever the weather allows. These plants spread rapidly and there is rarely any need for more than one plant, unless you are using them for ground cover when you should plant them about 2ft (60cm) apart. These plants are completely hardy and will survive the winter without any problems.

This species is sometimes confused with another campanula with an unpronounceable name, Campanula portenschlagiana, which has a very similar appearance, but is less invasive and has darker, less star-like flowers.

Growing Requirements

Position
This campanula is will grow in either full sun or moderate shade and in any type of garden soil. They do best in well-drained soils and in rich soils they are quite likely to become rampant. There should be no need to water them unless there is a drought.

Size
Plants will grow to a height of 10in (25cm) and spread indefinitely!

Propagation
It is usually easy to find a few rooted stems that can be potted up to produce new plants. This is best done in spring, but can be done at any other time of the year. Campanula poscharskyana is also easy to divide.
