Abstract

A new and distinct cultivar of Viburnum plant named ‘NCVP1’ with a compact habit, and white flowers in spring that rebloom in summer. ‘NCVP1’ is a new cultivar of doublefile Viburnum, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Viburnum hybrid.
Variety denomination: ‘NCVP1’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct doublefile Viburnum cultivar hereinafter referred to by the cultivar name ‘NCVP1’. This new doublefile Viburnum was developed through a breeding program at Mills River, N.C. ‘NCVP1’ was selected from an F2 population of seedlings derived from Viburnum plicatum tomentosum H2008-058-076 (‘Molly Schroeder’ x ‘Summer Snowflake’)(not patented). The first asexual propagation of ‘NCVP1’ was carried out in July 2013 by rooting stem cuttings at a research greenhouse in Mills River, N.C. and has been asexually reproduced repeatedly by vegetative cuttings over a 8-year period. ‘NCVP1’ roots readily from softwood cuttings treated with a basal dip of 3,000-4,000 ppm indole butyric acid (potassium salt) in water. ‘NCVP1’ has been found to retain its distinctive characteristics through successive asexual propagations.
SUMMARY OF THE INVENTION
The following are the unique combination of characteristics of this new cultivar when grown under standard horticultural practices at a research greenhouse in Mills River, N.C.
    • 1. A compact habit with dense branching.
    • 2. Abundant white flowers in spring with repeat blooming in summer.
    • 3. Burgundy-red fall foliage color.
COMPARISON WITH PARENT VARIETIES
Records of the parent variety characteristics are not available. The inventor cannot make a comparison to the seed parent. The pollen parent is unknown.
COMPARISON WITH COMMERCIAL CULTIVARS
‘NCVP1’ is distinguished from Viburnum plicatum f. tomentosum ‘Summer Snowflake’(unpatented) in that ‘NCVP1’ has a smaller, more compact habit to 120 cm tall and wide, whereas V. plicatum f. tomentosum ‘Summer Snowflake’ grows to about 200 cm tall. ‘NCVP1’ is distinguished from V. plicatum f. tomentosum ‘Mariesii’(unpatented) in that ‘Mariesii’ will grow taller and wider than 200 cm tall, and ‘NCVP1’ will remain compact. ‘NCVP1’ is distinguished from Viburnum plicatum f. tomentosum ‘Molly Schroeder’ (unpatented) in that ‘NCVP1’ has pure white sterile flowers and V. plicatum f. tomentosum ‘Molly Schroeder’ has pink sterile flowers. ‘NCVP1’ is distinguished from ‘SMNVPTFD’, U.S. Plant Pat. No. 29,553 in having a larger habit (120 cm tall and wide) compared to 60 to 90 cm and 90 to 120 cm wide habit of SMNVPTFD’. The plant habit of ‘NCVP1’ is globose and upright, whereas the habit of ‘SMNVPTFD’ is more horizontally spreading. The new variety does not form fruit; ‘SMNVPTFD’ forms berries in the Fall.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
This new doublefile 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. 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 Viburnum. Plants in the photographs are approximately 2 years old.
