Abstract

A new and distinct cultivar of Sambucus plant named ‘SMNSRD4’, characterized by its compact, upright to outwardly spreading and mounded plant habit; vigorous growth habit; freely branching habit; dense and bushy habit; finely-dissected leaves that are bright yellow green in the spring and/or under full sunlight conditions and yellow green in the late summer and/or under partial shade conditions; leaves that are resistant to sun scalding; and good garden performance.

Description

Botanical designation: Sambucus racemosa.

Cultivar denomination: ‘SMNSRD4’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Sambucus plant, botanically known as Sambucus racemosa and hereinafter referred to by the name ‘SMNSRD4’.

The new Sambucus plant is a product of a controlled breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program is to create new Sambucus plants with attractive leaf color and sun-tolerance.

The new Sambucus plant originated from a cross-pollination in May, 2006 in Grand Haven, Mich. of Sambucus racemosa ‘Dropmore Fernleaf’, not patented, as the female, or seed, parent with Sambucus racemosa ‘Sutherland Gold’, not patented, as the male, or pollen, parent. The new Sambucus plant was discovered and selected by the Inventor in May, 2009 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Grand Haven, Mich.

Asexual reproduction of the new Sambucus plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since June, 2009 has shown that the unique features of this new Sambucus plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Sambucus 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 ‘SMNSRD4’. These characteristics in combination distinguish ‘SMNSRD4’ as a new and distinct Sambucus plant:

- 1. Compact, upright to outwardly spreading and mounded plant habit.
- 2. Vigorous growth habit.
- 3. Freely branching habit; dense and bushy habit.
- 4. Finely-dissected leaves that are bright yellow green in the spring and/or under full sunlight conditions and yellow green in the late summer and/or under partial shade conditions.
- 5. Leaves that resist sun scalding.
- 6. Good garden performance.

Plants of the new Sambucus can be compared to plants of the female parent, ‘Dropmore Fernleaf’. Plants of the new Sambucus differ from plants of ‘Dropmore Fernleaf’ in the following characteristics:

- 1. Plants of the new Sambucus are more compact than plants of ‘Dropmore Fernleaf’.
- 2. In the spring and/or under full sunlight conditions, leaves of plants of the new Sambucus are bright yellow green in color whereas leaves of plants of ‘Dropmore Fernleaf’ are green in color.

Plants of the new Sambucus can be compared to plants of the male parent, ‘Sutherland Gold’. Plants of the new Sambucus differ from plants of ‘Sutherland Gold’ in the following characteristics:

- 1. Plants of the new Sambucus are more compact than plants of ‘Sutherland Gold’.
- 2. Leaves of plants of the new Sambucus are more finely dissected than leaves of plants of ‘Sutherland Gold’.
- 3. Under full sunlight conditions, leaves of plants of the new Sambucus resist sun scalding whereas leaves of plants of ‘Sutherland Gold’ are not resistant to sun scalding.

Plants of the new Sambucus can be compared to plants of the Sambucus nigra ‘Eiffel 1’, disclosed in U.S. Plant Pat. No. 23,633. Plants of the new Sambucus differ from plants of ‘Eiffel 1’ in the following characteristics:

- 1. Plants of the new Sambucus are upright to outwardly spreading and mounding whereas plants of ‘Eiffel 1’ are columnar in shape.
- 2. Leaves of plants of the new Sambucus are bright yellow green to yellow green in color whereas leaves of plants of ‘Eiffel 1’ are dark purple in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Sambucus 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 Sambucus plant.

The photograph on the first sheet is a side perspective view of a typical plant of ‘SMNSRD4’ grown in an outdoor nursery under full sunlight conditions.

The photograph on the second sheet is a side perspective view of a typical plant of ‘SMNSRD4’ grown in an outdoor nursery under partial shade conditions.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer in three-liter containers and ground beds in an outdoor nursery in Grand Haven, Mich. and under cultural practices typical of commercial production. Plants were three years 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.
