plant named ‘Eiffel 1’

Abstract

A new cultivar of Sambucus named ‘Eiffel 1’ characterized by its upright, columnar plant habit, its dark purple foliage, its dark purple mature stems, its pink flowers and its large, dark black-purple berries.

Description

Genus/species: Sambucus nigra.

Varietal denomination: ‘Eiffel 1’.

RELATED APPLICATIONS

This application is related to an application filed for a cultivar derived from the same parentage entitled Sambucus Plant Named ‘Gerda’ (U.S. Plant Pat. No. 12,305).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sambucus nigra and will be referred to hereafter by its cultivar name, ‘Eiffel 1’. ‘Eiffel 1’ represents a new cultivar of Elderberry a deciduous shrub grown for landscape use.

The new Sambucus originated from a breeding program conducted by the Inventor in West Mailing, Kent, United Kingdom. An initial cross was made in 1990 between ‘Pyramidalis’ (not patented) and ‘Guincho Purple’ (not patented). ‘Eiffel 1’ arose from a cross made in June 1993 from two unnamed selected seedlings from the initial cross as the parent plants. ‘Eiffel 1’ was selected in 2000 as a single unique plant from amongst the 300 seedlings that has been planted out for evaluation in 1994 and propagated plants were grown in further trials through summer of 2010 to evaluate its mature stature and characteristics.

Asexual reproduction of the new cultivar was first accomplished by stem cuttings by the Inventor in East Mailing, Kent, United Kingdom in summer of 2000. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Sambucus. These attributes in combination distinguish ‘Eiffel 1’ as a distinct cultivar of Sambucus.

• • 1. ‘Eiffel 1’ exhibits an upright, columnar plant habit.
  • 2. ‘Eiffel 1’ exhibits foliage that is very dark purple in color.
  • 3. ‘Eiffel 1’ exhibits stems that mature to a dark purple color.
  • 4. ‘Eiffel 1’ exhibits pink flowers.
  • 5. ‘Eiffel 1’ exhibits large berries that mature to a very dark black-purple color.

‘Eiffel 1’ can be readily distinguished from its parent plants. The male parent differs in having had foliage that is crinkled and unattractive, and having a less columnar plant habit. The female parent differs in having white flowers. ‘Eiffel 1’ can also be compared to the plants used in the first generation of the parents. ‘Pyramidalis’ is similar to ‘Eiffel 1’ in having an erect plant habit, however ‘Pyramidalis’ differs from ‘Eiffel 1’ in having green foliage and creamy white flowers. ‘Guincho Purple’ differs from ‘Eiffel 1’ in having a more spreading plant habit, having foliage that is lighter purple and more bronze in color and flowers that are creamy white in color with pink anthers. ‘Eiffel 1’ can be most closely compared to ‘Gerda’ that arose from the same parentage as ‘Eiffel 1’. ‘Gerda’ is very similar in foliage and flower coloration, however the habit of ‘Gerda’ is spreading and not columnar. ‘Eiffel 1’ can also be compared to the cultivars ‘Eva’ (U.S. Plant Pat. No. 15,575) and ‘Thundercloud’ (not patented). ‘Eva’ is similar to ‘Eiffel 1’ in having dark purple foliage, however ‘Eva’ differs from ‘Eiffel 1’ in having laciniate leaves and in having a spreading plant habit. ‘Thundercloud’ differs from ‘Eiffel 1’ in having lighter purple foliage, a spreading and more open plant habit, smaller leaves and leaflets, and in being less robust.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographs illustrate the characteristics of the new cultivar of Sambucus.

The photograph in FIG. 1 was taken of a 2 and one-half year-old plant as grown in a trial plot at a nursery in North Wales, United Kingdom and provides a side view of ‘Eiffel 1’ in bloom.

The photographs in FIG. 2 and FIG. 3 were taken of a two year-old plant as grown in a garden in Maldon, Essex, United Kingdom. FIG. 2 provides a close-up view of the developing fruit and FIG. 3 provides a close-up view of a leave of ‘Eiffel 1’. The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Sambucus.
