Botanical designation: Campanula carpatica.

Cultivar denomination: ‘Violet Teacups’.


The first public disclosure of the claimed plant was made by Walters Gardens, Inc. on Feb. 1, 2018 when the claimed plant was displayed as a photograph with short description on a website owned and operated by Walters Gardens, Inc., and the initial sales of the new plants was on Oct. 8, 2018, also by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Campanula ‘Violet Teacups’ have been sold, in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the filing date of this application, and such disclosure within one year was either derived directly or indirectly from the inventor.


The present invention relates to the new and distinct clustered bellflower herein also referred to as Campanula ‘Violet Teacups’, by the cultivar name, ‘Violet Teacups’, or as the new plant. The new plant was derived from a cross made on May 14, 2015 from a plant in a greenhouse research facility in Zeeland, Mich. The female parent was a selected seedling privately identified as ‘AF-001’ (not patented) and the male parent was the same seedling privately identified as ‘AF-001’. ‘AF-001’ is a selection from ‘Arend's Form’ (not patented) that was self-pollinated. The single selected seedling from this cross represented by ‘Violet Teacups’ was selected from a group of seedlings by the inventor, isolated and compared in subsequent years to other Campanula and subsequently found to be different from all cultivars known to the discoverer and eventually given the breeder code 15-5-1.

Asexual propagation at the same nursery in Zeeland, Mich., USA by basal cuttings has shown ‘Violet Teacups’ to be stable and reproduce true to type in successive generations since late June 2016.


Campanula ‘Violet Teacups’ has not been observed in all possible environmental conditions. The phenotype may, vary slightly with changes in environments such as light intensity, fertility, water availability, etc. without, however any variation in genotype.

Campanula ‘Violet Teacups’ is distinct from all cultivars known to the inventor in the following traits:

    • 1. Small, cordate to deltoid, serrate, medium-green foliage with compact height and dense mounded habit.
    • 2. Heavily-branched with strong purple bell-shaped flowers clustered at the nodes and ends of stems.
    • 3.Long flowering period beginning in late spring and continuing for at about 14 weeks.

Plants of Campanula ‘Violet Teacups’ are most similar to plants of the seed variety ‘Rapido Blue’ (not patented). ‘Rapido Blue’ has a shorter flowering season, less flower coverage in peak flower and the flowers are larger and not as violet in color. ‘AF-001’ has a flatter flower with shallower cupping. The new plant has denser habit than both ‘Arend's Form’ and ‘AF-001’.


The color drawings illustrate the overall characteristics of Campanula ‘Violet Teacups’ as a three-year-old plant. The colors are as true as reasonably possible given the technology available. The color values may vary slightly depending on light intensity and quality.

FIG. 1 shows the new plant in a landscape environment.

FIG. 2 shows a close-up of the flowers and buds of the new plant.


The following description is based on one and three-year-old plants growing in a full-sun trial garden and a partially shaded greenhouse in Zeeland, Mich., USA. Environmental conditions for the growing season daytime temperatures range between 12° C. to 35° C., and night temperatures range between 6° C. to 24° C. Except for ordinary dictionary color usage, color references are according to The Royal Horticultural Society Colour Chart, 2015 edition. The new plant has not been observed in all possible growing conditions and may vary in phenotypic characteristics based on water availability, light conditions, fertilizer, temperatures, etc. without varying in genotypic characteristics.
