Abstract
A new and distinct cultivar of Ilex plant named ‘RutHol6’, characterized by its full, oval growth habit; a height-to-width ratio of about 1.3; grayish-red new growth, and wider leaves than similar Ilex cultivars.
Description
Botanical designation: Hybrid Ilex cultivar.
Cultivar denomination ‘RutHol6’.
The present invention relates to a new and distinct hybrid cultivar of Ilex (holly), and hereinafter referred to by the cultivar name ‘RutHol6’.
The new Ilex cultivar is the product of a planned breeding program conducted by the inventor in Watkinsville, Ga. The objective of the Ilex breeding program is to create new plant cultivars with novel forms of growth, good cold hardiness, and resistance to damage from spider mites, insects and diseases.
The new Ilex cultivar ‘RutHol6’ is a product of a cross between the unpatented offspring of (Ilex crenata (unpatented) x Ilex maximowicziana (unpatented)) crossed with Ilex viridis (unpatented). ‘RutHol6’ has been evaluated for container production and evaluated through trials at a horticultural farm in Watkinsville, Ga. since about 2016.
Asexual reproduction of the new Ilex cultivar has been continued by vegetative terminal cuttings in a controlled environment in Dearing, Ga. and Watkinsville, Ga. since about 2014. Observations of the resulting progeny have shown that the unique features of the new Ilex cultivar are stable and reproduced true to type in successive generations.
The new Ilex cultivar ‘RutHol6’ has not been observed under all possible environmental conditions. The phenotypes may vary somewhat with variations in environment and cultural practices such as temperature, water and fertility levels, soil types, and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique and distinguishing characteristics of the new Ilex cultivar named ‘RutHol6’. In combination, this combination of traits set ‘RutHol6’ apart from all other existing varieties of Ilex, including the parents, known to the inventors.
-
- 1. Oval growth habit having a more oval shape than other Ilex selections;
- 2. A height to width ratio of about 1.3;
- 3. New growth that is grayish-red in contrast to yellow-green mature leaves; and
- 4. Wider leaves than most other Ilex cultivars, having a length to width ratio of 2.3.
Plants of the ‘RutHol6’ differ from the most similar Ilex cultivars based on at least some of the above characteristics. The maternal parent is no longer available, so direct comparison is not possible. Neither of the grandparent cultivars, nor parent Ilex virdis exhibits the grayish-red new growth of ‘RutHol6’. ‘RutHol6’ has a wider leaf with a larger L:W ratio (2.3) than either I. maximowicziana (2.0) or Ilex viridis (1.7). ‘RutHol6’ also has a larger leaf aspect (about 55-65°) than grandparent Ilex viridis (about 15-35°). ‘RutHol6’ can also be compared to commercial cultivar Ilex crenata ‘MAD-IC1’ (U.S. Plant Pat. No. 32,035), which does not have the grayish-red colored new growth of ‘RutHol6’. Compared to ‘MAD-IC1’, ‘RutHol6’ is faster growing with a greater final height and more upright form, and ultimate leaves that are larger with undulate margins in contrast to the cupped leaves of ‘MAD-IC1’.
The accompanying colored photographic illustrations show the overall appearance and distinct characteristics of the new cultivar of Ilex ‘RutHol6’ showing the colors as true as possible. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description. The photographs were taken of plants grown outdoors in Watkinsville, Ga. in May of 2021 and are described in the captions below.
The photograph labeled FIG. 1 depicts a full view of a typical 6-year-old ‘RutHol6’ plant showing the symmetrical, ovoid growth habit.
The photograph labeled FIG. 2 depicts a close-up view of some branches of a typical 6-year-old ‘RutHol6’ plant showing the grayish-red new growth.
The following traits have been consistently observed in the original plants of the new ‘RutHol6’ and in asexually propagated progeny grown in Watkinsville, Ga., and, to the best knowledge of the inventors, their combination forms the unique characteristics of the new variety Ilex ‘RutHol6’.
Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart, 6th edition published by The Royal Horticultural Society, London, England in 2015, except where general terms of ordinary dictionary significance are used.
The aforementioned photographs and following observations, measurements, and values describe plants of the Ilex cultivar named ‘RutHol6’. Data were collected from a horticulture farm in Watkinsville, Ga. from 6-year-old plants. The average low temperatures ranged from about 15° F. to 30° F. in the winter and about 90° F. to 100° F. in summer.
