plant named ‘Armitpp02’

Abstract

A new cultivar of Chelone named ‘Armtipp02’, characterized by its sturdy stems that are held upright, its large flowers that are dark pink in color, its foliage that is dark green and matures to a blend of dark green and black, and its numerous flowers per stem with blooms commencing early in the season.

Description

Botanical classification: Chelone lyonii.

Varietal denomination: ‘Armtipp02’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chelone plant, botanically known as Chelone lyonii ‘Armtipp02’ and will be referred to hereinafter by its cultivar name, ‘Armtipp02’.

‘Armtipp02’ was derived from a controlled breeding program conducted by the Inventor in a nursery in De Lier, The Netherlands. ‘Armtipp02’ was selected in July of 2010 by the Inventor as a single unique plant derived from a cross made in July of 2009 between an unnamed plant of Chelone lyonii as the female parent and an unnamed plant of Chelone lyonii from the Inventor's breeding program, identified with accession No. 1225, as the male parent.

Asexual propagation of the new cultivar was first accomplished by stem cuttings by the Inventor in Kerkdriel, the Netherlands in July of 2010. Propagation by stem cuttings has determined that the characteristics of this cultivar are 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 cultivar as grown in De Lier, The Netherlands. These attributes in combination distinguish ‘Armtipp02’ as a unique cultivar of Chelone.

• • 1. ‘Armtipp02’ exhibits sturdy upright stems.
  • 2. ‘Armtipp02’ exhibits large flowers that are dark pink in color.
  • 3. ‘Armtipp02’ exhibits foliage that is dark green and matures to a blend of dark green and black.
  • 4. ‘Armtipp02’ exhibits numerous flowers per stem with blooms commencing early in the season.
    The female parent and typical plants of Chelone lyonii differ from ‘Armtipp02’ in having less flowering stems, lighter pink flowers, weaker stems and in being taller in height. The male parent differs from ‘Armtipp02’ in having weaker stems and flowers that are smaller and lighter pink in color. ‘Armtipp02’ can be compared to the cultivar ‘Hot Lips’ (not patented). ‘Hot Lips’ is similar to ‘Armtipp02’ in having drak green foliage that is tinged with black and in having deep pink flowers, but differs from ‘Armtipp02’ in having stems that are red in color most of the season.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The plants and plant parts in the photographs were taken of a two year-old plant of ‘Armtipp02’ as grown outdoors in a 17-cm container in Kerdriel, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘Armtipp02’ in bloom.

The photograph in FIG. 2 is a close-up view of the flowers of ‘Armtipp02’.

The photograph in FIG. 3 is a close-up view of a mature leaf of ‘Armtipp02’.

The 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 Chelone.
