Abstract

A new and distinct cultivar of Philadelphus plant named ‘SMNPVB’, characterized by its compact, upright to somewhat outwardly spreading and uniformly mounding plant habit; moderately vigorous growth habit and rapid growth rate; freely branching habit; dense and bushy appearance; green and greenish yellow variegated leaves; numerous fragrant white-colored flowers; and good garden performance.

Description

Botanical designation: Philadelphus hybrida.
Cultivar denomination: ‘SMNPVB’.
STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE
The Inventor/Applicant and Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Philadelphus plant, botanically known as Philadelphus hybrida, commonly referred to as Mock Orange and hereinafter referred to by the cultivar name ‘SMNPVB’.
The new Philadelphus is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to develop new compact and freely flowering Philadelphus plants with unique leaf coloration.
The new Philadelphus plant is a naturally-occurring whole plant mutation of an unnamed proprietary selection of Philadelphus hybrida, not patented. The new Philadelphus plant was discovered and selected by the Inventor during the spring of 2015 as a single plant from within a population of plants of the mutation selection in a controlled environment in Grand Haven, Mich.
Asexual reproduction of the new Philadelphus plant by softwood stem cuttings in a controlled greenhouse environment in Grand Haven, Mich. since 2015 has shown that the unique features of this new Philadelphus plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Philadelphus have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SMNPVB’. These characteristics in combination distinguish ‘SMNPVB’ as a new and distinct Philadelphus plant:
    • 1. Compact, upright to somewhat outwardly spreading and uniformly mounding plant habit.
    • 2. Moderately vigorous growth habit and rapid growth rate.
    • 3. Freely branching habit; dense and bushy appearance.
    • 4. Green and greenish yellow variegated leaves.
    • 5. Numerous fragrant white-colored flowers.
    • 6. Good garden performance.
Plants of the new Philadelphus can be compared to plants of the mutation parent selection. In side-by-side comparisons, plants of the new Philadelphus have variegated leaves whereas plants of the mutation parent selection have non-variegated leaves.
Plants of the new Philadelphus can also be compared to plants of Philadelphus lemoinei ‘Innocence’, not patented. In side-by-side comparisons, plants of the new Philadelphus differ primarily from plants of ‘Innocence’ in the following characteristics:
    • 1. Plants of the new Philadelphus are more compact than plants of ‘Innocence’.
    • 2. Plants of the new Philadelphus are more freely branching and denser than plants of ‘Innocence’.
    • 3. Developing leaves of plants of the new Philadelphus are more highly variegated than developing leaves of plants of ‘Innocence’.
    • 4. Plants of the new Philadelphus are less susceptible to sun scalding than plants of ‘Innocence’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Philadelphus plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Philadelphus plant.
The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘SMNPVB’.
The photograph on the second sheet (FIG. 2) is close-up view of typical leaves of ‘SMNPVB’.
The photograph on the third sheet (FIG. 3) is a close-up view of typical flowers of ‘SMNPVB’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in the spring in three-gallon containers in a polypropylene-covered shadehouse in Grand Haven, Mich. and under cultural practices typical of commercial Philadelphus production. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from 5° C. to 10° C. Plants were three years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
