Abstract
A new cultivar of Hosta named ‘Roy Klehm’, a chemically induced chimeral mutation of Hosta ‘Summer Serenade’, that is characterized by its unique variegated foliage with bright yellow-green centers and wide deep green margins comprising about one half of the leaf area. ‘Roy Klehm’ has an upright plant habit with leaves held horizontal on upright petioles and near white flowers held on erect flower scapes that arise above the foliage in mid summer.
Description
Botanical classification: Hosta hybrida.
Cultivar designation: ‘Roy Klehm’.
The present invention, Hosta ‘Roy Klehm’, relates to a new and distinct cultivar of Hosta, botanically known as a Hosta hybrida, hereinafter referred to as ‘Roy Klehm’.
The inventor discovered the new cultivar, ‘Roy Klehm’, in summer of 2002 in a trial garden outdoors in Waseca, Minn. ‘Roy Klehm’ originated as a chemically induced chimeral mutation of Hosta ‘Summer Serenade’(unpatented), ‘Summer Serenade’ is a chimeral mutation of ‘Piedmont Gold’ (not patented).
Asexual reproduction of the new cultivar was first accomplished by the inventor utilizing in vitro propagation in Waseca, Minn. in fall of 2005. Asexual reproduction of the new cultivar by division and tissue culture has shown that the unique features of ‘Roy Klehm’ are stable and reproduced true to type in successive generations.
The following traits have been repeatedly observed in trials in Minnesota for a period of five years and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Roy Klehm’ as a new and unique cultivar of Hosta.
-
- 1. The foliage of ‘Roy Klehm’ is variegated with bright yellow-green centers and wide deep green margins with margin width ranging from 2 to 8 cm. The margin comprises about one half of the leaf area.
- 2. ‘Roy Klehm’ has an upright vase-shaped plant habit with leaves held nearly horizontal on the petioles.
- 3. ‘Roy Klehm’ reaches a height of about 53 cm, exclusive of flower scapes, and a spread of about 83 cm in five years.
- 4. ‘Roy Klehm’ blooms in mid summer with near white flowers held above the foliage on erect flower scapes.
In comparison to the parent plant, ‘Summer Serenade’, ‘Roy Klehm’ has leaf margins that are significantly wider than those of ‘Summer Serenade’ and the plant habit of ‘Roy Klehm’ is upright, whereas the plant habit of ‘Serenade’ is mounded. The closest comparison plants to ‘Roy Klehm’ are chimeral mutations of gold foliaged ‘Piedmont Gold’: ‘Satisfaction’ (not patented), which differs in having the reverse variegation pattern with green centers and gold margins and in having a mounded plant habit and ‘Lakeside Symphony’ (not patented), which differs in having yellowish-white (lutescent) centers and pale green margins and a mounded plant habit. One could also compare ‘Roy Klehm’ to ‘Journey's End’ (U.S. Plant Pat. No. 16,895), a cultivar with a similar variegation pattern. ‘Journey's End’ differs from ‘Roy Klehm’ most significantly in having narrower margins, undulated margins, and a mounded plant habit.
The accompanying colored photographs illustrate the distinct foliage characteristics of the new Hosta. The photographs were taken of a five year-old plant of ‘Roy Klehm’ as grown outdoors in a trial garden in Waseca, Minn.
The photograph in FIG. 1 was taken in late July shows a plant of ‘Roy Klehm’ in bloom and illustrates the plant habit.
The photograph in FIG. 2 was taken in June and provides a close-up view of the foliage. 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 Hosta.
The following is a detailed description of five 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.
