Botanical designation: Campanula carpatica: Cultivar denomination: ‘Midnight’.
STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)
The new plant was first sold in Poland on Feb. 27, 2022, by Danziger who obtained the new plant and all information relating thereto, indirectly from the inventor. Information including a brief description and photographs of the claimed new plant was posted on a website operated by Walters Gardens, Inc. on Dec. 1, 2023. No plants of Campanula ‘Midnight’ 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 to the filing date of the provisional application.
BACKGROUND OF THE PLANT
The present invention relates to the new and distinct Bellflower herein also referred to as Campanula ‘Midnight’, by the cultivar name, ‘Midnight’, or as the new plant. The new plant was derived from a cross made on Jul. 8, 2016, from a plant in a greenhouse research facility in Zeeland, Michigan. The female parent was ‘Violet Teacups’ U.S. Plant Pat. No. 32,844 and the male parent was a proprietary, unreleased, and unnamed selection known only as 15-6-2 (not patented). The single selected seedling from this cross represented by ‘Midnight’ was selected from a group of seedlings by the inventor, isolated, 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 16-1-1 prior to being assigned a cultivar epithet.
Asexual propagation at the same nursery in Zeeland, MI, USA by basal cuttings has shown ‘Midnight’ to be stable and reproduce true to type in successive generations since late June 2017.
SUMMARY OF THE PLANT
Campanula ‘Midnight’ 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 ‘Midnight’ 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 for about 14 weeks beginning late spring and continuing until hard frost.
Plants of Campanula ‘Midnight’ are most similar to plants of the variety ‘Rapido Blue’ (not patented), ‘Blue Clips’ (not patented), and ‘Violet Teacups’. ‘Rapido Blue’ has a shorter flowering season, less flower coverage in peak flower, the flowers are larger and the flower center is light blue. ‘Blue Clips’ has a larger habit and slightly larger flowers with a shorter flowering season. ‘Violet Teacups’ has a larger habit and a more funnel-shaped flower with deeper cupping and a more violet and less bluish coloration.
BRIEF DESCRIPTION OF THE DRAWINGS
The color drawings illustrate the overall characteristics of Campanula ‘Midnight’ as a five-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.

DETAILED BOTANICAL DESCRIPTION
The following description is based on one and five-year-old plants growing in a full-sun trial garden and a partially shaded greenhouse in Zeeland, MI, USA. Except for ordinary dictionary color usage, color references are according to The Royal Horticultural Society Colour Chart, sixth edition, 2015. 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.
