Claims
I claim:
1. The new and distinct cultivar of Campanula plant named `Violet
Teacups` as described and illustrated.
Description
Botanical designation: Campanula carpatica.
Cultivar denomination: `Violet Teacups`.
STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)
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.
BACKGROUND OF THE PLANT
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.
SUMMARY OF THE PLANT
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`.
BRIEF DESCRIPTION OF THE DRAWINGS
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.
DETAILED BOTANICAL DESCRIPTION
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.degree. C. to
35.degree. C., and night temperatures range between 6.degree. C. to
24.degree. 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. Parentage: Female or seed parent is the seedling
selection known only privately as `AF-001`; male or pollen parent
is the same seedling selection known only privately as `AF-001`;
