Hosta plant names ‘Journey's End’

Abstract

A new cultivar of Hosta named ‘Journey's End’, a sport of Hosta ‘Choo Choo Train’, that is characterized by its unique variegated foliage with yellow-green centers and green margins comprising about one third to one half of the leaf area. ‘Journey's End’ has a mounded plant habit of large broad leaves, a vigorous growth rate, and pale lavender flowers held above the foliage in early to mid summer.

Description

RELATED APPLICATIONS

This application is co-pending with U.S. Plant patent application Ser. No. 11/099,729 filed for a cultivar derived from the same parent entitled Hosta Plant Named ‘American Icon’.

Botanical classification: Hosta sp.

Cultivar designation: ‘Journey's End’.

BACKGROUND OF THE INVENTION

The present invention, Hosta ‘Journey's End’, relates to a new and distinct cultivar of Hosta, botanically known as a Hosta sp., hereinafter referred to as ‘Journey's End’.

The inventor discovered the new cultivar, ‘Journey's End’, in summer of 1999 in a tissue culture lab in Waseca, Minn. ‘Journey's End’ originated as a naturally-occurring chimeral mutation of Hosta ‘Choo Choo Train’ (unpatented). The parent plant, Hosta ‘Choo Choo Train’, is non-variegated with yellow-green foliage. ‘Journey's End’ is unique in having foliage with green margins surrounding yellow-green centers. The closest comparison plant is ‘American Icon’ (patent pending), a sibling of ‘Journey's End’, which differs in having leaves with the reverse variegation pattern to ‘Journey's End’, yellow-green margins and green centers. ‘Journey's End’ can also be compared to ‘Summer Serenade’ (not patented), a plant of similar plant stature and leaf variegation pattern. ‘Summer Serenade’ is a chimeral mutation of golden foliaged ‘Piedmont Gold’ (not patented). ‘Summer Serenade’ differs form ‘Journey's End’ in having less ruffled leaf margins and by emerging earlier in the spring resulting in susceptibility to frost damage, particularly in the Southern portions of the U.S.

Asexual reproduction of the new cultivar was first accomplished by the inventor utilizing in vitro propagation in Waseca, Minn. in fall of 2002. Asexual reproduction of the new cultivar by division and tissue culture has shown that the unique features of ‘Journey's End’ are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed in trials in Iowa and Minnesota for a period of six years and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Journey's End’ as a new and unique cultivar of Hosta.

• • 1. The foliage of ‘Journey's End’ is variegated with green margins and yellow-green centers, with margin width ranging from 3 to 9 cm comprising about one third to one half of the leaf area. The foliage of the parent plant, ‘Choo Choo Train’, is non-variegated with yellow-green foliage.
  • 2. ‘Journey's End’ has large broad leaves with a mounded plant habit.
  • 3. ‘Journey's End’ reaches a height of about 61 cm, exclusive of flower scapes, and a spread of about 132 cm in six years.
  • 4. ‘Journey's End’ has large leaves with undulating margins when mature.
  • 5. ‘Journey's End’ blooms in early to mid summer with pale lavender flowers that arise above the foliage.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hosta. The photographs were taken in June of mature plants of ‘Journey's End’ and ‘Choo Choo Train’ as grown outdoors in Waseca, Minn. under the same conditions for six years.

FIG. 1 provides an overall view of the foliage and plant habit of the new cultivar, ‘Journey's End’.

The photograph in FIG. 2 provides a comparison between a leaf of ‘Journey's End’ (shown on left) and ‘Choo Choo Train’ (shown on right) as grown in medium shade.

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

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of six year-old plants of the new cultivar as grown outdoors in Waseca, Minn. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
