Abstract

A new and distinct Hemerocallis cultivar is provided. The new cultivar is very floriferous and forms attractive highly ruffled deep yellow flowers displaying a burgundy eye zone and edges, substantial substance, and a funnel-shaped form over an extended period of time. In U.S.D.A. Hardiness Zone No. 6, blooming commonly begins during late June and commonly ends during mid-August. The new cultivar displays a plurality of fans and a plurality of scapes per fan. The new cultivar is well suited for growing as distinctive colorful ornamentation in the landscape.

Description

Botanical/commercial classification: Hemerocallis hybrida/Daylily.

Varietal denomination: cv. Mean Mister Mustard.

SUMMARY OF THE INVENTION

The present invention comprises a new and distinct cultivar of Hemerocallis plant of the dormant type, and hereinafter is referred to by the cultivar name ‘Mean Mister Mustard’.

The new cultivar is the product of a planned breeding program which had as its objective the creation of a new Daylily cultivar that is intended for use as attractive ornamentation in the landscape.

The cross that resulted in the production of the new cultivar of the present invention was carried out in a controlled environment during May, 1996, at Bridgeton, N.J., U.S.A. The female parent (i.e., the seed parent) of the new cultivar was the ‘Strawberry Candy’ cultivar (non-patented in the United States) which displays rich pink and red flowers having a diameter of approximately 10 cm and less than optimum substance.

The male parent (i.e., the pollen parent) of the new cultivar was the ‘Barbara Keen Strout’ cultivar (non-patented in the United States) which displays creamy yellow and burgundy flowers of less than optimum substance. Each of the parent plants is registered with the American Hemerocallis Society.

The parentage of the new cultivar of the present invention can be summarized as follows:
‘Strawberry Candy’×‘Barbara Keen Strout’.

The seeds resulting from the above pollination were sown and small plantlets were obtained which were physically and biologically different from each other. A number of such plants were transplanted into the field at Bridgeton, N.J., U.S.A., during June 1997. Selective study during June 1998 resulted in the identification of a single plant of the new cultivar.

It was found that the new Hemerocallis plant of the present invention is of the dormant type and:

- (a) forms attractive highly ruffled deep yellow flowers having a burgundy eye zone and edge, substantial substance, and a funnel-shaped form,
- (b) possesses a long blooming season with repeat blooming,
- (c) exhibits a propensity to readily display a plurality of fans, and
- (d) readily forms a plurality of scapes per fan over the flowering season.

The ‘Mean Mister Mustard’ cultivar resembles some well-known cultivars, such as the ‘Stella D' Oro’ cultivar (non-patented in the United States) and the ‘Happy Returns’ cultivar (non-patented in the United States) in the sense that it commonly possesses an unusually long and substantially continuous blooming season (i.e., a multiple repeat character) of up to 75 days in U.S.D.A. Hardiness Zone No. 6. Such blooming commonly begins during late June and commonly ends during mid-August. This compares to a bloom period of less than about 30 days for over 99 percent of the hybrid Daylilies that are available in the trade.

As indicated, the ‘Mean Mister Mustard’ plant exhibits attractive highly ruffled deep yellow flowers bearing a burgundy eye zone and edges that readily can be distinguished from the orange-yellow flowers of the ‘Stella D' Oro’ cultivar and the medium yellow flowers of the ‘Happy Returns’ cultivar. To the best knowledge of the originator, the ‘Mean Mister Mustard’ cultivar is the first long and substantially reblooming Daylily having flowers that exhibit such a unique blend of multi-colored attributes.

The new cultivar can form up to 5 or more fans per year. This compares to approximately 6 to 8 fans per year for the ‘Stella D' Oro’ cultivar and the ‘Happy Returns’ cultivar. Most Daylily cultivars form only approximately 2 to 3 fans per year. Also, the new cultivar commonly forms several scapes per fan during the flowering season, unlike most Daylilies that commonly produce only one scape per fan.

Asexual reproduction of the new cultivar by division was initially carried out on Aug. 15, 1998 at Bridgeton, N.J., U.S.A. At the time of such asexual reproduction the original plant of the new cultivar consisted of a clump of four fans that were phenotypically identical to each other. More specifically, the clump of the new cultivar was removed from the field and the fans were divided. It has been demonstrated that the characteristics of the new cultivar are firmly fixed and are well retained following this asexual reproduction.

The ‘Mean Mister Mustard’ plant has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light, day length, contact with pesticides, etc.

The new cultivar will be marketed by the Assignee beginning in June, 2008.

DETAILED DESCRIPTION

The chart used in the identification of the colors described herein is the R.H.S. Colour Chart of The Royal Horticultural Society, London, England. In some instances, more common color terms are provided and are to be accorded their usual dictionary significance. The original plant of the new cultivar is described when observed during August 2006 while growing at Bridgeton, N.J., U.S.A. under field growing conditions.
