Abstract

A new and distinct cultivar of Exochorda plant named ‘Niagara’, characterized by its compact, upright, outwardly spreading and mounding plant habit; easy to propagate; freely branching habit; freely flowering habit; large white-colored flowers; and good garden performance.

Description

Botanical designation: Exochorda macrantha×Exochorda racemosa.
Cultivar denomination: ‘NIAGARA’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Exochorda plant, botanically known as Exochorda macrantha×Exochorda racemosa and hereinafter referred to by the name ‘Niagara’.
The new Exochorda plant is a product of a planned breeding program conducted by the Inventor in Boskoop, The Netherlands. The objective of the breeding program is to develop new uniform Exochorda plants with fast rooting and good container performance.
The new Exochorda plant originated from a cross-pollination in 1994 Exochorda macrantha ‘The Bride’, not patented, as the female, or seed, parent with an unnamed selection of Exochorda racemosa, as the male, or pollen, parent. The new Exochorda plant was discovered and selected by the Inventor in 1997 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Boskoop, The Netherlands.
Asexual reproduction of the new Exochorda plant by softwood cuttings in a controlled greenhouse environment in Boskoop, The Netherlands since 1998 has shown that the unique features of this new Exochorda plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Exochorda have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Niagara’. These characteristics in combination distinguish ‘Niagara’ as a new and distinct cultivar of Exochorda:
    • 1. Compact, upright, outwardly spreading and mounding plant habit.
    • 2. Easy to propagate.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Large white-colored flowers.
    • 6. Good garden performance.
Plants of the new Exochorda can be compared to plants of the female parent, ‘The Bride’. Plants of the new Exochorda differ from plants of ‘The Bride’ in the following characteristics:
    • 1. Plants of the new Exochorda are easier to propagate than plants of ‘The Bride’.
    • 2. Plants of the new Exochorda are more compact and mounding than plants of ‘The Bride’.
    • 3. Plants fo the new Exochorda have larger flowers than plants of ‘The Bride’.
Plants of the new Exochorda can be compared to plants of the male parent selection. Plants of the new Exochorda differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Exochorda are easier to propagate than plants of the male parent selection.
    • 2. Plants of the new Exochorda are more compact than plants of the male parent selection.
    • 3. Plants fo the new Exochorda are more freely flowering than plants of the male parent selection.
Plants of the new Exochorda can be compared to plants of Exochorda serratifolia ‘Snow White’, not patented. Plants of the new Exochorda differ primarily from plants of ‘Snow White’ in the following characteristics:
    • 1. Plants of the new Exochorda are easier to propagate than plants of ‘Snow White’.
    • 2. Plants of the new Exochorda are more compact than plants of ‘Snow White’.
    • 3. Plants of the new Exochorda are not as vigorous as plants of ‘Snow White’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Exochorda 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 Exochorda plant.
The photograph on the first sheet is a side perspective view of a typical plant of ‘Niagara’ grown in an outdoor nursery.
The photograph on the second sheet is a close-up view of typical flowers and leaves of ‘Niagara’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants of the new Exochorda grown in an outdoor nursery in Boskoop, The Netherlands during the spring under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 9° C. to 18° C. and night temperatures ranged from 1° C. to 12° C. Plants were four years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
