Abstract

A new cultivar of Polygonatum biflorum ‘Kelli's Gold’ characterized by its golden yellow foliage and its ability to maintain its foliage coloration and vigor when grown under bright shady conditions.

Description

Genus and species: Polygonatum biflorum.
Cultivar: ‘Kelli's Gold’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Polygonatum biflorum and will be referred to hereafter by its cultivar name, ‘Kelli's Gold’. ‘Kelli's Gold’ represents a new Solomon's seal, an herbaceous perennial grown for landscape use.
The inventor collected and sowed seed from various unnamed plants of Polygonatum biflorum in 1989. ‘Kelli's Gold’ was selected from within a population of seedlings that were grown out from the seed collected from the unnamed plants of Polygonatum biflorum in Brookings, S.D. in the summer of 1990.
The new Solomon Seal was selected for its golden yellow foliage coloration. This characteristics makes this new cultivar unique and unlike any other known cultivars of Polygonatum biflorum known to the inventor.
Asexual reproduction of the new cultivar was first accomplished by rhizome division in Brookings, S.D. in spring of 1992 by the inventor. 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 cultivar. These attributes in combination distinguish ‘Kelli's Gold’ as unique from all other selections and forms of Polygonatum biflorum known to the inventor.
1. Foliage is yellow in color and the coloration is maintained throughout the growing season. Foliage color is less yellow in heavier shade and on foliage that is basal and shaded by upper foliage.
2. Growth rate and foliage color is maintained in bright shade.
3. Vigorous growing rate once roots are established.
4. Tolerant to heavy clay soils.
5. Hardy to at least Zone 4.
6. Grows to a height of 45 to 60 cm (18 to 24 in).
7. Greenish-white flowers develop in late spring and bloom for about three weeks, followed by blue-black berries in summer.
BRIEF DESCRIPTION OF THE DRAWING
The plants and plant parts in the Figures depict a three-year-old plant in a three-gallon container as grown from a single rhizome division of ‘Kelli's Gold’ in Brookings, S.D. The plant was grown outdoors in bright shade.
Figure One is a digital photograph illustrating the foliage coloration when in peak bloom.
Figure Two is a digital photograph showing a close-up of the flowers.
The colors in the photographs are as close as possible while utilizing digital photography.
BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the new cultivar as grown in a three-gallon container as grown for three years from a single rhizome division of ‘Kelli's Gold’ in Brookings, S.D. 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 RHS Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
Botanical classification: ‘Kelli's Gold’ is a cultivar of Polygonatum biflorum.
Commercial Classification: Solomon's seal.
Parentage: Seedling from seeds collected from unnamed plants of Polygonatum biflorum.
