Abstract

A new and distinct cultivar of Nandina plant named ‘ZhNan28’, characterized by a combination of compact growing form, dense foliage, orange red (apricot) fall foliage persistent to 6 months, no seed, and no notable disease and pest.

Description

Botanical designation: Nandina domestica.
Cultivar denomination ‘ZhNan28’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Nandina, botanically know as Nandina domestica, and hereinafter referred to by the cultivar name ‘ZhNan28’.
The new Nandina domestica ‘ZhNan28’ is a product of a planned breeding program conducted by the inventors at a horticulture farm in Watkinsville, Ga. The objective of the Nandina breeding is to create new plant cultivars with compact habit, bright and colorful foliage, and less seed-bearing characteristics.
The new Nandina domestica ‘ZhNan28’ is a product of a selection from open pollinated seedling population. Seeds were collected on Sep. 23, 2012 from six compact-growing plants labeled as ‘Nandina01-02’ to ‘Nandina06-02’ (all 6 plants were not patented) at the horticulture farm in Watkinsville, Ga. and directly saw them into the germination flat. A total of 1108 germinated seedlings were transplanted into one-gallon containers on Mar. 11, 2013 for evaluation. On Oct. 8, 2014, seedlings without compact growing habit were discarded and 644 seedlings were grown on the nursery area for further evaluation as red, yellow and apricot foliage groups. Five plants from apricot foliage group were selected for further evaluation and Nandina domestica ‘ZhNan28’ was finally selected on Dec. 8, 2015.
Asexual reproduction of the new Nandina domestica ‘ZhNan28’ using vegetative terminal cuttings and tissue culture in controlled environment has been continued in Watkinsville, Ga. since 2014. Observations of the resulting ‘ZhNan28’ progeny have shown that the unique features of this new Nandina domestica ‘ZhNan28’ are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The new Nandina cultivar ‘ZhNan28’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as water 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 Nandina domestica cultivar named ‘ZhNan28’. In combination, these traits set ‘ZhNan28’ apart from all other existing varieties of Nandina domestica known to the inventors.
    • 1. Compact growing form.
    • 2. Dense foliage.
    • 3. Orange red (apricot) fall foliage.
    • 4. Orange red (apricot) foliage persistent to 6 months
    • 5. No flower and seed observed.
    • 6. No notable disease and pest.
Plants of the new Nandina differ from plants of Nandina domestica cultivar ‘Gulf Stream’ (U.S. Plant Pat. No. 5,656) in the following characteristics:
    • 1. Plants of the new Nandina exhibit orange red (apricot) fall foliage.
    • 2. Plants of the new Nandina are extremely compact, with tighter branches and denser foliage.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographic illustrations show the overall appearance and distinct characteristics of the new cultivar of Nandina domestica ‘ZhNan28’ showing the colors as true as possible. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describes the colors of the new Nandina domestica ‘ZhNan28’. The photographs were taken of plants grown outdoors in Watkinsville, Ga. on Jan. 6, 2016.
The photograph labeled FIG. 1 depicts a top view of a typical 3-year-old ‘ZhNan28’ plant showing the orange red foliage.
The photograph labeled FIG. 2 depicts a close-up view of the leaves of a typical 3-year-old ‘ZhNan28’ plant showing the orange red foliage.
The photograph labeled FIG. 3 depicts a side view of a typical 3-year-old ‘ZhNan28’ plant showing the orange red foliage.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements, and values describe plants of the Nandina domestica cultivar named ‘ZhNan28’. Data were collected from a horticulture farm and nursery in Watkinsville, Ga. from 3-year-old plants (planted into 3-gallon container). The average low temperatures ranged from about 22-23° F. to 67-68° F. in the winter and about 66-67° F. to 97-98° F. in summer. The data below were collected on Jan. 6, 2016. Color names and values are from The R.H.S. Colour Chart, 5th edition, published by The Royal Horticultural Society (R.H.S.), London, UK in 2007, except where general terms of ordinary dictionary significance are used.
