BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hemerocallis plant of hybrid origin, botanically known as Hemerocallis ‘SPd 06-01’ and will be referred to hereafter by its cultivar name, ‘SPd 06-01’.

The new cultivar was developed through on on-going breeding program conducted by the Inventor in McIntosh, Fla. The objectives of the breeding program are to develop new cultivars of tetraploid Hemerocallis that exhibit early and continuous flowering on recurrent, branched scapes with high bud counts and flowers that fully open during cool conditions, have bright flower color, heavy petal substance, and clean shedding of the old flowers to allow new buds to fully develop. Further objectives of the breeding program include developing plants that exhibit a high multiplication rate, short blooms stalks, foliage that is grass-like and compact, cold and heat hardiness and resistance to daylily rust.

The Inventor made crosses in summer of 2005 between specific unnamed proprietary male and female parents in his breeding line and pooled all the resulting seed from his crosses and evaluated the resulting seedlings based on the objectives of the breeding program. ‘SPd 06-01’ was selected as a single unique plant from the resulting seedlings in summer of 2006. The specific parents are unknown.

Asexual reproduction of the new cultivar was first accomplished by division in McIntosh, Fla. in 2006 by the Inventor. Propagation by division and tissue culture has determined that the characteristics of this cultivar are 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 ‘SPd 06-01’. These attributes in combination distinguish ‘SPd 06-01’ as a new and distinct cultivar of Hemerocallis.

• • 1. ‘SPd 06-01’ exhibits flowers that are about 12 cm in diameter and are coral pink in color with rosy-red eyezones and green throats.
  • 2. ‘SPd 06-01’ exhibits flower petals that are broadly elliptic in shape, heavy in substance, and have lightly ruffled edges.
  • 3. ‘SPd 06-01’ exhibits a blooming habit that commences very early in the season with continuous re-bloom until frost on recurrent, branched scapes with high bud counts.
  • 4. ‘SPd 06-01’ exhibits flowers that fully open under cool growing conditions and cleanly shed spent flowers to allow new buds to fully develop.
  • 5. ‘SPd 06-01’ has foliage that is evergreen, semi-evergreen or dormant depending on the growing climate, which allows its suitability to a variety of growing climates.
  • 6. ‘SPd 06-01’ is a tetraploid.
  • 7. ‘SPd 06-01’ exhibits a compact plant habit with grass-like foliage with short blooms scapes that allow for ease of transporting of finished plants.
  • 8. ‘SPd 06-01’ is readily propagated by division or tissue culture and exhibits a fast multiplication rate (fan increase).
  • 9. ‘SPd 06-01’ is cold and heat hardy at least in U.S.D.A. Zones 4 to 11.
  • 10. ‘SPd 06-01’ exhibits a very high tolerance to daylily rust (Puccinia hemerocallidis).

The new cultivar can be compared in flower coloration to the cultivars ‘Black Preppy Pink’ (not patented) and ‘Sirocco’ (not patented). Both cultivars differ from ‘SPd 06-01’ in having foliage that goes dormant under all conditions, in having taller flower scapes, in having less flowers that are smaller in size and do not open fully in cold weather, in blooming later in the season with less recurrent blooming, in having wider and taller foliage that lacks daylily rust resistance, and in having a slower multiplication rate. ‘SPd 06-01’ can also be most closely compared to cultivars from the same breeding program. These cultivars differ from ‘Spd 06-01’ primarily in flower coloration. ‘SPd 06-02’ exhibits flowers that are golden yellow in color with maroon to burgundy red eyezones, ‘SPd 06-08’ exhibits flowers that are peach to melon in color with tangerine and pink highlights, ‘SPd 06-11’ exhibits flowers that are tomato red in color with a yellow-green throat, ‘SPd 06-12’ exhibits flowers that are burgundy rose in color with a darker burgundy eye, ‘SPd 06-13’ exhibits flowers that are light yellow in color, ‘SPd 06-16’ exhibits flowers that are golden yellow in color with a gold-green throat.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Hemerocallis. The photographs were taken in early spring of a two year-old plant of ‘SPd 06-01’ as grown outdoors in a field plot from a single fan in McIntosh, Fla. without fungicide treatment, growth regulators or deadheading.

The photograph in FIG. 1 illustrates its early flowering, grass-like foliage, high bud counts, short scapes, and self-cleaning of blooms of ‘SPd 06-01’.

The photograph in FIG. 2 provides a close-up view of a flower of ‘SPd 06-01’. The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the new Hemerocallis.
