plant named ‘Versluck’

Abstract

A new cultivar of Phlox plant named ‘Versluck’ that is characterized by its dwarf plant habit, its re-blooming habit, its flowers that are a blend of white and violet-purple on color with an eye that is dark pink in color, its strong basal branching, and its partial resistance to powdery mildew.

Description

Botanical classification: Phlox paniculata.

Cultivar designation: ‘Versluck’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is related to U.S. Plant Patents for plants derived from the same breeding program that is entitled Phlox Plant Named ‘Verscan’ (U.S. Plant Pat. No. 27,558) and Phlox Plant Named ‘Versde’ (U.S. Plant Pat. No. 27,557).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phlox paniculata and will be referred to hereafter by its cultivar name, ‘Versluck’. ‘Versluck’ represents a new herbaceous perennial grown for landscape use.

‘Versluck’ was discovered by the Inventor as a chance seedling in a trial field in Haarlem, The Netherlands in 2014. The parentage is unknown.

Asexual propagation of the new cultivar was first accomplished by stem cuttings by the Inventor in 2015 in Haarlem, The Netherlands. Asexual propagation by stem cuttings, root cuttings, and tissue culture using meristematic tissue has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Versluck’ as a unique cultivar of Phlox.

• • 1. ‘Versluck’ exhibits a very dwarf plant habit.
  • 2. ‘Versluck’ exhibits a re-blooming habit.
  • 3. ‘Versluck’ exhibits flowers that are a blend of white and violet-purple on color with an eye that is dark pink in color.
  • 4. ‘Versluck’ exhibits strong basal branching.
  • 5. ‘Versluck’ exhibits some resistance to powdery mildew.

‘Versluck’ can be compared to Phlox paniculata cultivars ‘Verscan’ and ‘Versde’. Both are similar to ‘Versluck’ in having very compact plant habits. ‘Verscan’ differs from ‘Versluck’ in having bi-color flowers that are red-purple and white in color. ‘Versde’ differs from ‘Versluck’ in having flowers that are pink in color.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or 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. The Applicant claims a prior art exemption 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. Disclosures include but may not be limited to website listings by Growing Colors, Soegel Home and Garden, Diane's Greenhouse, and Vite Greenhouses.
