USPP26013P2 - Gentiana plant named ‘Little Pinkie’ - Google Patents

Abstract

A new cultivar of Gentiana plant named ‘Little Pinkie’ that is characterized by its upright, clumping plant habit, its abundant blooms and long flowering period; blooming from May to October in the Netherlands and its flowers that are a distinct purple-pink color even when the flowers are closed.

Description

Botanical classification: Gentiana hybrida.

Varietal denomination: ‘Little Pinkie’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gentiana of interspecific hybrid origin in which Gentiana scabra is one of the known species in the background of the parentage. ‘Little Pinkie’ represents a new Gentian, an herbaceous perennial grown for landscape use.

The new cultivar was derived from a controlled breeding program by the Inventor in Aukland, New Zealand. The Inventor made a cross between an unnamed proprietary plants in the Inventor's breeding program, reference no. 5W65 as the female parent and reference no. Pink A as the male parent. The Inventor selected ‘Little Pinkie’ as a single unique plant in February of 2008 amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor by in vitro propagation Aukland, New Zealand in April of 2008. Asexual propagation by stem cuttings and tissue culture has been determined that the characteristics of the new 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. These attributes in combination distinguish ‘Little Pinkie’ as a new and unique cultivar of Gentiana.

• • 1. ‘Little Pinkie’ exhibits an upright, clumping plant habit.
  • 2. ‘Little Pinkie’ exhibits abundant blooms and a long flowering period; blooming from May to October in the Netherlands.
  • 3. ‘Little Pinkie’ exhibits flowers that are a distinct purple-pink color even when the flowers close.

The female parent of ‘Little Pinkie’, ref no. 5W65, differs from ‘Little Pinkie’ in having red flowers. The male parent of ‘Little Pinkie’, ref no. Pink A., differs from ‘Little Pinkie’ in having flowers that are more pink in color and borne on longer stems. ‘Little Pinkie’ can be most closely compared to the Gentiana scabra cultivar ‘Zuki Rindo’ (not patented). ‘Zuki Rindo’ is similar to ‘Little Pinkie’ in blooming late in the season. ‘Zuki Rindo’ differs from ‘Little Pinkie’ in blooming later in the fall, in having smaller flowers that are more grey-pink in color when they are closing, in having 50% less flowers, in having thinner stems, and in having a more spreading, groundcover-like plant habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Gentiana. The photographs were taken of plants 12 months in age as grown in a half open greenhouse in a 2-liter container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a side view of the plant habit of ‘Little Pinkie’.

The photograph in FIG. 2 provides a close-up view of the flowers of ‘Little Pinkie’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘Little Pinkie’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Gentiana.
