Abstract

A new and distinct Viburnum cultivar plant named ‘NCVX1’ is disclosed, characterized by highly glossy, semi-evergreen foliage, which exhibits Fall color of red to purple. Plants are compact with a uniquely prostrate branching habit. Abundant cymes are produced with 150 to 400 florets. The new variety is a Viburnum normally produced as an outdoor garden or container plant.

Description

Classification: Viburnum hybrid.
Variety denomination: ‘NCVX1’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct variety of Viburnum, hereinafter referred to by the cultivar name ‘NCVX1’. This new Viburnum was developed through a breeding program at North Carolina State University, Mills River, N.C. ‘NCVX1’ was selected from a population of seedlings grown from an open-pollinated F1 hybrid Viburnum (lobophyllum×japonicum) ‘Huron’ (unpatented) growing in an isolation block with Viburnum (japonicum×dilatatum) ‘Chippewa’ (unpatented).
The first asexual propagation of ‘NCVX1’ was carried out in July 2009 by rooting stem cuttings at the North Carolina State University, Mountain Horticultural Crops Research Station, Mills River, N.C. and has been asexually reproduced repeatedly by vegetative cuttings and in tissue culture over a 5 year period. ‘NCVX1’ roots readily from softwood cuttings treated with a basal dip of 4,000-5,000 ppm indole butyric acid (potassium salt) in water. ‘NCVX1’ has been found to retain its distinctive characteristics through successive asexual propagations.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under standard horticultural practices at North Carolina State University, Mountain Horticultural Crops Research Station, Mills River, N.C.
    • 1. Compact form with dense, prostrate, branching habit.
    • 2. Semi-evergreen with highly glossy foliage.
    • 3. Abundant cymes containing 150-400 small white florets.
    • 4. Red to purple fall and winter foliage color.
COMPARISON WITH PARENTS
‘NCVX1’ is distinguished from its female parent Viburnum ‘Huron’ by its growth habit and foliage. ‘NCVX1’ has a compact, prostrate habit and extremely glossy, semi-evergreen leaves. Viburnum ‘Huron’ is a large upright shrub with dull, semi-evergreen leaves. ‘NCVX1’ is distinguished from Viburnum ‘Chippewa’ in that ‘NCVX1’ has a compact, mounding habit and Viburnum ‘Chippewa’ is a large, upright, rounded shrub.
COMPARISON WITH COMMERCIAL VARIETIES
‘NCVX1’ is similar in most horticultural characteristics to Viburnum ‘Heneke’ U.S. Plant Pat. No. 12,870. The new variety however differs in the following:
    • 1. ‘NCVX1’ has a red flush to the mature foliage, this comparator has entirely green foliage.
    • 2. ‘NCVX1’ has burgundy Fall foliage, not seen in this comparator.
‘NCVX1’ can also be compared to Viburnum ‘Michael Dodge’, unpatented. The new variety however differs in the following:
    • 1. ‘NCVX1’ has dark green foliage with a red flush. ‘Michael Dodge’ has light green foliage.
    • 2. ‘NCVX1’ has broader and rounder foliage than ‘Michael Dodge’.
    • 3. ‘NCVX1’ has burgundy Fall foliage. ‘Michael Dodge’ has orange Fall foliage.
DESCRIPTION OF THE PHOTOGRAPHS
This new Viburnum is illustrated by the accompanying photographs which show the plant's form, foliage and inflorescences. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.
FIG. 1. Shows cymes with multiple florets in April 2014 in Mills River, N.C.
FIG. 2. Shows glossiness of foliage of a young container-grown plant in April 2014 in Mills River, N.C.
FIG. 3. Shows the overall habit of a container-grown plant in April 2014 in Mills River, N.C.
FIG. 4. Shows the fall and winter foliage color in November 2013 in Arden, N.C.
 DESCRIPTION OF THE NEW CULTIVAR
The following detailed description sets forth the distinctive characteristics of ‘NCVX1’. The detailed description was taken on 4-year-old plants growing in Mills River, N.C. in April 2014. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 2001 Edition.
