Abstract: A new and distinct cultivar of Lantana plant named `Robmornrog`, characterized by its outwardly spreading and mounding plant habit; freely branching habit, dense and bushy appearance; freely flowering habit; and flowers that are golden yellow in color, then becoming orange and eventually dark pink.
Claim: It is claimed:

1. A new and distinct cultivar of Lantana plant named `Robmornrog`, as illustrated and described.
Description: Botanicalclassification/cultivar designation: Lantana camara cultivar Robmornrog.


The present Invention relates to a new and distinct cultivar of Lantana plant, botanically known as Lantana camara, and hereinafter referred to by the cultivar name Robmornrog.

The new Lantana is a product of a planned breeding program conducted by the Inventor in Grain Valley, Mo. The objective of the breeding program is to create mounded and freely branching Lantanas that are freely flowering.

The new Lantana originated from a self-pollination made by the Inventor in 1997 of the Lantana camara cultivar Robpatdes, disclosed in U.S. Plant Pat. No. 10,156. The new Lantana was selected as a single plant from the resulting progeny of theself-pollination by the Inventor in a controlled environment in 1998 in Grain Valley, Mo.

Asexual reproduction of the new cultivar by terminal cuttings taken in Grain Valley, Mo. since 1998, has shown that the unique features of this new Lantana are stable and reproduced true to type in successive generations.


Plants of the cultivar Robmornrog have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture such as temperature, light intensity and daylength without, however,any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Robmornrog`. These characteristics in combination distinguish `Robmornrog` as a new and distinct cultivar: 1. Outwardly spreading andmounding plant habit. 2. Freely branching habit, dense and bushy appearance. 3. Freely flowering habit. 4. Flowers that are golden yellow in color, then becoming orange and eventually dark pink.

Plants of the new Lantana are most similar to plants of the parent cultivar. In side-by-side comparisons conducted in Grain Valley, Mo., plants of the new Lantana differed from plants of the cultivar Robpatdes in the following characteristics:1. Plants of the new Lantana were smaller than plants of the cultivar Robpatdes. 2. Plants of the new Lantana had shorter internodes than plants of the cultivar Robpatdes.


The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Lantana.

The photograph at the top of the sheet comprises a side perspective view of a typical plant of `Robmornrog` in a container.

The photograph at the bottom of the sheet comprises a close-up view of typical leaves and inflorescences of `Robmornrog`.


Plants used for the aforementioned photographs and following observations and measurements were grown for about 19 weeks in 15.25-cm containers and were pinched twice. Plants were grown in a polycarbonate-covered greenhouse in Lompoc, Calif. during the spring and summer with day temperatures ranging from 21 to C., night temperatures ranging from 16 to C., and light levels ranging from 5,000 to 9,000 foot-candles. In the following description, color references aremade to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
