Campanula plant named ‘Camgood’

Campanula poscharskyana cultivar ‘Camgood’.

The present Invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula poscharskyana , is marketed under the trade name Blue Waterfall, and hereinafter referred to by the name ‘Camgood’.

The new Campanula originated from a cross made by the Inventors of the Campanula poscharskyana cultivar ‘Stella’, not patented, as the female, or seed parent, with an unnamed selection of Campanula poscharskyana , not patented, as the male, or pollen, parent. The cultivar ‘Camgood’ was discovered and selected by the Inventors as a flowering plant within the progeny of the stated cross in a controlled environment in 1996 in Bressingham, United Kingdom.

Asexual reproduction of the new cultivar by divisions and basal cuttings taken at Bressingham, United Kingdom, since June, 1996, has shown that the unique features of this new Campanula are stable and reproduced true to type in successive generations.

Plants of the cultivar ‘Camgood’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, fertility type or rate, and/or water status without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Camgood’. These characteristics in combination distinguish ‘Camgood’ as a new and distinct cultivar:

1. Rapid growth rate, vigorous growth habit.

2. Clumping and spreading growth habit, dense plants.

3. Freely flowering habit.

4. Long flowering period.

5. Violet blue campanulate flowers.

Plants of the new Campanula differ from plants of the parents in the following characteristics:

1. Plants of the new Campanula have larger leaves than plants of the parents.

2. Plants of the new Campanula are more outwardly spreading in habit than plants of the parents.

3. Plants of the new Campanula are more freely flowering and have larger flowers than plants of the parents.

4. Flowers of plants of the new Campanula are more blue in color than flowers of plants of the parents.

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Campanula.

The photograph comprises a side perspective view of a typical plant of ‘Camgood’ grown in the landscape for two growing seasons.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Plants were grown in Bressingham, United Kingdom under field conditions which closely approximate commercial production conditions. During the production of the plants, day temperatures ranged from 5 to 28° C. and night temperatures ranged from −8 to 15° C. Plants used for the description were grown for two growing seasons in 5-liter containers.
