USPP35610P2 - Ilex plant named ‘Jenny’ - Google Patents

Abstract

A new cultivar of Ilex crenata plant named ‘Jenny’ that is characterized by its highly vigorous growth habit with strong and fast-growing root systems, its flat leaves, its foliage that is bright green in color when young and dark green in color when mature, its male flowers that lack fruit production, and its neat and densely branched plant habit.

Description

Botanical classification: Ilex crenata.

Variety denomination: ‘Jenny’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is related to a European plant breeders' rights application filed on Oct. 16, 2020, application No. 2020/2556. The Applicant received the information for the Plant breeders' rights application directly from the Inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ilex crenata and will be referred to hereafter by its cultivar name, ‘Jenny’. ‘Jenny’ is a new cultivar of Japanese holly grown for use as an ornamental landscape plant.

‘Jenny’ was discovered by the Inventor as a chance seedling in a trial field in Hazerswoude-Dorp, The Netherlands in 2013. The parentage is unknown as there were numerous cultivars of Ilex crenata growing in the trial field.

Asexual propagation of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in 2013 in Hazerswoude-Dorp, The Netherlands. Asexual propagation by softwood stem cuttings 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 observed repeatedly and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Jenny’ as a unique cultivar of Ilex.

• • 1. ‘Jenny’ exhibits a highly vigorous growth habit with strong and fast-growing root systems.
  • 2. ‘Jenny’ exhibits flat leaves.
  • 3. ‘Jenny’ exhibits foliage that is bright green in color when young and dark green n color when mature.
  • 4. ‘Jenny’ exhibits male flowers only and lacks fruit production.
  • 5. ‘Jenny’ exhibits a neat and densely branched plant habit.

‘Jenny’ can be most closely compared to the Ilex crenata cultivars ‘Caroline Upright’ (not patented), ‘Glory Gem’ (not patented) and ‘Convexa’ (not patented). ‘Caroline Upright’ differs from ‘Jenny’ in having weaker and slower growing root system, young shoots that are darker green in color, a slower growing plant habit, leaves that are larger in size and a less dense branching habit. ‘Glory Gem’ differs from ‘Jenny’ in having thicker leaves that are less flat and smaller in size, young foliage that is darker green in color, a slower growing root system, and has a higher susceptibility to disease. ‘Convexa’ differs from ‘Jenny’ in having leaves that are less flat, foliage that is darker green in color, a higher susceptibility to disease, a less compact and more irregular growth habit, and in being a female plant that produces berries.

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 disclosures and/or sales that fall within a one-year grace period to the filing date. Disclosures include website listings by vida-verde, Arboretum, Lucan Garden Centre, Proctors Nursery, bijstox, Hornbach, Clarenbridge Garden Centre, floraxchange, pelckmans, Stewarts Garden Centres, and Ebay.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of six-month-old plants of the new cultivar as grown outdoors in a 17-cm containers in Muge, Portugal.

The photograph in FIG. 1 provides a side view of the plant habit of ‘Jenny’.

The photograph in FIG. 2 provides a close-up view of the mature foliage of ‘Jenny’.

The photograph in FIG. 3 provides a comparison of the foliage between ‘Jenny’ (left) and towards the right ‘Carolina Upright’, ‘Convexa’, and ‘Glory Gem’.

The 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 Ilex.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of one-year-old plants of the new cultivar grown outdoors in 19-cm containers in Hazerswoude-Dorp, The Netherlands.
