Abstract

A new and distinct cultivar of Viburnum plant named ‘Spiro’, characterized by its upright and somewhat outwardly spreading plant habit; vigorous growth habit; freely branching habit; red purple-colored flower buds; numerous strongly fragrant light pink to white-colored flowers; and good garden performance.

Description

Botanical designation: Viburnum carlesii.
Cultivar denomination: ‘SPIRO’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Viburnum plant, botanically known as Viburnum carlesii and hereinafter referred to by the name ‘Spiro’.
The new Viburnum plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program is to develop new fragrant Viburnum plants with unique and attractive foliage and flower coloration.
The new Viburnum plant originated from an open-pollination in 1999 of an unnamed selection of Viburnum carlesii, not patented, as the female, or seed, parent with an unknown selection of Viburnum carlesii, not patented, as the male, or pollen, parent. The new Viburnum plant was discovered and selected by the Inventor in 2009 as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.
Asexual reproduction of the new Viburnum plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since the spring of 2009 has shown that the unique features of this new Viburnum plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Viburnum have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Spiro’. These characteristics in combination distinguish ‘Spiro’ as a new and distinct Viburnum plant:
    • 1. Upright and somewhat outwardly spreading plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Red purple-colored flower buds.
    • 5. Numerous strongly fragrant light pink to white-colored flowers.
    • 6. Good garden performance.
Plants of the new Viburnum can be compared to plants of the female parent selection. Plants of the new Viburnum differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Viburnum are more vigorous than plants of the female parent selection.
    • 2. Flower buds of plants of the new Viburnum are darker in color than flower buds of plants of the female parent selection.
    • 3. Flowers of plants of the new Viburnum are more fragrant than flowers of plants of the female parent selection.
Plants of the new Viburnum can be compared to plants of the Viburnum carlesii ‘Compactum’, not patented. Plants of the new Viburnum differ from plants of ‘Compactum’ in the following characteristics:
    • 1. Plants of the new Viburnum are not as compact as plants of ‘Compactum’.
    • 2. Plants of the new Viburnum are faster growing than plants of ‘Compactum’.
    • 3. Flower buds of plants of the new Viburnum are darker in color than flower buds of plants of ‘Compactum’.
    • 4. Flowers of plants of the new Viburnum are more fragrant than flowers of plants of ‘Compactum’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Viburnum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. 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 plant.
The photograph on the first sheet is a side perspective view of a typical plant of ‘Spiro’ grown in an outdoor nursery.
The photograph on the second sheet is a close-up view of a developing inflorescence of ‘Spiro’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants of the new Viburnum grown during the spring in ground beds in an outdoor nursery in Grand Haven, Mich. and under cultural practices which closely approximate commercial Viburnum production. Plants were one year old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
