Abstract: A new cultivar of Ligularia, `Last Dance`, an interspecific hybrid of Ligularia hiberniflora and Farfugium japonicum, characterized by its medium sized leaves with dentate margins, its compact plant habit, and its abundant bright yellow inflorescences that are densely arranged on well-branched scapes.
Claim: It is claimed:

1. A new and distinct cultivar of Ligularia plant named `Last Dance` as herein illustrated and described.
Description: Botanicalclassification: Ligularia hybrid.

Cultivar designation: `Last Dance`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ligularia, botanically an interspecific hybrid, and hereinafter referred to by the cultivar name `Last Dance`.

The new cultivar resulted from a cross made in the Inventor's garden in Marietta, Ga. in 1998 between an unnamed plant of Ligularia hiberniflora as the female parent and an unnamed plant of Farfugium japonicum (syn. Ligularia tussilaginea) asthe male parent (both unpatented). The new cultivar was selected as a single unique plant from the resulting seedlings by the Inventor in 1998.

Asexual reproduction of the new cultivar was first accomplished by division by the Inventor in Marietta, Ga. in 2000. Asexual reproduction of the new culthar by division and tissue culture has shown that the unique features of `Last Dance` arestable and 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 `Last Dance` as a new and unique cultivar of Ligularia. 1. `Last Dance` has leaves thatintermediate in size in comparison to its parents. 2. `Last Dance` has leaves with a dentate margin. 3. `Last Dance` has a compact habit. 4. `Last Dance` has yellow composite inflorescences that are densely clustered on well-branched scapes.

`Last Dance` differs from its female parent, Ligularia hiberniflora, in having larger leaves, larger and more abundant inflorescences, and a taller plant height. `Last Dance` differs from its male parent, Farfugium japonica, in having leaveswith a dentate margin rather than an entire margin, in having a more compact plant habit, in being shorter in plant height and in having inflorescences that are more abundant and compact and have a greater number of ray florets that are borne on morewell-branched scapes. `Last Dance` can also be compared to cultivars of Farfugium japonica, `Aureomaculata` and `Jitsuko's Star`. `Aureomaculata` differs from `Last Dance` in being shorter in height, having spotted foliage, a lower bloom count, leafedges that are undulated rather than dentate, and an earlier bloom season. `Jitsuko's Star` differs from `Last Dance` in having more heart-shaped and cupped foliage, in being taller in height in bloom, and in having double flowers with star-like rayfloret petals.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Ligularia. The photographs in the figures were taken of four-year-old plants of `Last Dance` as grown in Marietta, Ga.

FIG. 1 provides a view of the habit and foliage characteristics of the new cultivar in bloom,

FIG. 2 shows a close-up view of the foliage in mid summer and

FIG. 3 provides a close-up view of the flowers.

The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Ligularia.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar as observed for eight years in Marietta, Ga. with the detailed botanical data collected on two year-old plants of the new cultivar as grown outdoors in a 2-quart container inAlpharetta, Ga. 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 the2007 R.H.S. Colour Chart of the Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. General description: Blooming habit.--Blooms for about one month in mid fall in Georgia. Planthabit.--Clump forming, robust, herbaceous perennial, compact, with blooms held above the foliage.
