Abstract

A new and distinct cultivar of Itea plant named ‘SMNIVDFC’, characterized by its upright to outwardly spreading plant habit; freely branching habit, dense and bushy appearance; attractive autumnal leaf color; freely flowering habit; fragrant white-colored flowers; and good garden performance.

Description

Botanical designation: Itea virginiana.
Cultivar denomination: ‘SMNIVDFC’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Itea plant, botanically known as Itea virginiana, commonly referred to as Virginia Sweetspire and hereinafter referred to by the name ‘SMNIVDFC’.
The new Itea plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to create new freely-branching Itea plants with fragrant flowers and attractive autumn leaf coloration.
The new Itea plant originated from an open-pollination in 2011 in Grand Haven, Mich. of an unnamed seedling selection of Itea virginiana, not patented, as the female, or seed, parent with an unknown selection of Itea virginiana as the male, or pollen, parent. The new Itea plant was discovered and selected by the Inventor as a single plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich. in 2014.
Asexual reproduction of the new Itea plant by softwood stem cuttings in a controlled environment in Grand Haven, Mich. since 2014 has shown that the unique features of this new Itea plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Itea have not been observed under all possible combinations of 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 ‘SMNIVDFC’. These characteristics in combination distinguish ‘SMNIVDFC’ as a new and distinct Itea plant:
    • 1. Upright to outwardly spreading plant habit.
    • 2. Freely branching habit, dense and bushy appearance.
    • 3. Attractive autumnal leaf color.
    • 4. Freely flowering habit.
    • 5. Fragrant white-colored flowers.
    • 6. Good garden performance.
Plants of the new Itea differ primarily from plants of the female parent selection in the following characteristics:
    • 1. During the summer, leaves of plants of the new Itea are darker green in color than leaves of plants of the female parent selection.
    • 2. During the autumn, leaves of plants of the new Itea are darker red and purple in color than leaves of plants of the female parent selection.
    • 3. Flowers of plants of the new Itea are more fragrant than flowers of plants of the female parent selection.
Plants of the new Itea can also be compared to plants of Itea virginiana ‘Sprich’, disclosed in U.S. Plant Pat. No. 10,988. In side-by-side comparisons, plants of the new Itea differ primarily from plants of ‘Sprich’ in the following characteristics:
    • 1. During the summer, leaves of plants of the new Itea are darker green in color than leaves of plants of ‘Sprich’.
    • 2. During the autumn, leaves of plants of the new Itea are darker red and purple in color than leaves of plants of ‘Sprich’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Itea 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 Itea plant.
The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘SMNIVDFC’ grown during the summer.
The photograph on the second sheet is a close-up view of a typical plant of ‘SMNIVDFC’ during the autumn.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the spring, summer and autumn in three-gallon containers in a polyethylene-covered greenhouse in Grand Haven, Mich. and under cultural practices typical of commercial production. Plants were two years old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from 5° C. to 10° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
