USPP12456P2 - Hemerocallis plant named ‘Dance Party’ - Google Patents

Abstract

A new and distinct cultivar of Hemerocallis plant named ‘Dance Party’ characterized by its small pastel yellow-colored flowers which are borne on branched scapes. The flowers do not fade in warm, bright conditions and are resistant to water spotting. Plants of ‘Dance Party’ bloom in mid-season and repeatedly throughout the growing season. Plants of ‘Dance Party’ are evergreen and highly branched, thus, they are attractive in landscapes. The plant grows vigorously and propagates easily by division or tissue culture.

Description

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Hemerocallis plant, hereinafter referred to by the cultivar name ‘Dance Party’. The genus Hemerocallis is a member of the family Liliaceae.

Hemerocallis comprises a genus of approximately 15 species of clump-forming, herbaceous perennials which are native to central Europe, China, and particularly, Japan. The flowers of Hemerocallis are lily-like and are borne in succession atop tall, frequently-branched scapes. Individual flowers last one day; thus, Hemerocallis is commonly know as ‘Daylily’ in commercial trade.

In recent years, Hemerocallis has been extensively hybridized, and many cultivars exist. Hemerocallis hybrids are hardy spring- and summer-blooming plants which are particularly well-adapted to landscape plantings.

The plants form clumps of fan-shaped crowns of vertically-ranked, keeled, strap-like leaves. Plants (individual crowns) range in size from approximately 20 cm to over 90 cm in spread. Depending upon the parentage, Hemerocallis hybrids may be deciduous, evergreen or semi-evergreen.

Hemerocallis hybrids come in a range of colors including orange, yellow, pink, reddish or purplish. The flowers are funnel-shaped or campanulate with six segments joined at the base into a tube.

Asexual propagation of Hemerocallis is frequently done by division. Propagation can also be done through the use of tissue culture practices.

The new cultivar ‘Dance Party’ is a product of a planned breeding program and was originated by the inventor, Matthew Kaskel, from a cross made during such a program in Homestead, Fla. in April of 1995. The male and female parents are proprietary Hemerocallis selections designated by number codes which are maintained by the inventor and used for breeding purposes only. The selection comprising the new variety was chosen after commencement of flowering of the progeny in April of 1996.

Asexual reproduction of the new cultivar by tissue culture and division was performed by the inventor in Homestead, Fla. and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar ‘Dance Party’ are firmly fixed and are retained through successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Dance Party’ which in combination distinguish this Hemerocallis as a new and distinct cultivar:

1. Flowers are relatively small, pastel yellow in color and thick-textured;

2. Flowers do not fade in warm, bright conditions and are resistant to water spotting;

3. Individual scapes are short and branched with many buds which open in succession for approximately 4 weeks;

4. Spent flowers shrivel, become inconspicuous, drop from the scape quickly, and do not interfere with the opening of subsequent flowers;

5. Plants begin blooming mid-season (May-June) and rebloom throughout a 90-day blooming season;

6. plants grow vigorously and propagate rapidly by division an tissue culture; and

7. plants have dark-green, evergreen foliage and a clumping habit making them attractive in landscapes even when not in bloom.

‘Dance Party’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, daylength and humidity, without any change in genotype.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photographic illustrations show typical characteristics of Hemerocallis ‘Dance Party’, with colors being as nearly true as possible with illustrations of this type.

The first drawing shows a 10-month-old plant of ‘Dance Party’ grown from tissue culture and flowering in a landscape setting.

The second drawing is a close-up view showing the characteristics of the flowers and scape.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe plants grown in Sebring, Fla., under landscape conditions which closely approximate those generally used in horticultural practice. Color references are made to The Royal Horticultural Society (R.H.S.) Colour Chart, except where general color terms of ordinary significance are used.

Parentage:

Male parent.—Proprietary selection of Hemerocallis.

Female parent.—Proprietary selection of Hemerocallis.

Propagation: Vegetative, by tissue culture or division.

Plant:

Form/growth habit.—Clump-forming; fan-shaped crowns of vertically ranked, opposite, smooth, keeled, ligulate leaves.

Individual flowers.—Number of sepals: three. Number of petals: three. Dimension: The diameter of the flower is approximately 8.2 cm to 9.0 cm. The sepals are approximately 5.4 cm long and approximately 3.1 cm wide. The petals are approximately 6.0 cm long and approximately 4.9 cm wide.
