Application Ser. No. 17/371,431

Filed: Concurrently with the instant application

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calylophus plant, botanically known as Calylophus hybrida, commonly referred to as Texas Primrose and hereinafter referred to by the name ‘WNCYLALEM’.

The new Calylophus plant is a product of a planned breeding program conducted by the Inventor in Bonsall, Calif. The objective of the breeding program is to create new vigorous, freely-branching and uniformly mounding Calylophus plants with numerous attractive flowers, long flowering period and good garden performance.

The new Calylophus plant originated from a self-pollination made by the Inventor on Apr. 25, 2017 in Bonsall, Calif. of a proprietary selection of Calylophus hybrida identified as code number 17TX073-02, not patented. The new Calylophus plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated self-pollination in a controlled greenhouse environment in Bonsall, Calif. on Sep. 13, 2018.

Asexual reproduction of the new Calylophus plant by vegetative terminal cuttings in a controlled greenhouse environment in Bonsall, Calif. since Sep. 18, 2018 has shown that the unique features of this new Calylophus plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calylophus have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘WNCYLALEM’. These characteristics in combination distinguish ‘WNCYLALEM’ as a new and distinct Calylophus plant:

- 1. Outwardly spreading and mounding to eventually trailing and decumbent plant habit.
- 2. Moderately vigorous to vigorous growth habit and rapid growth rate.
- 3 Freely branching habit; dense and bushy plant form.
- 4. Freely flowering habit.
- 5. Large light yellow-colored flowers that are held above and beyond the foliar plane.
- 6. Excellent garden performance.

Plants of the new Calylophus can be compared to plants of the parent selection. In side-by-side comparisons, plants of the new Calylophus differ primarily from plants of the parent selection in the following characteristics:

- 1. Plants of the new Calylophus flower for a longer period of time than plants of the parent selection.
- 2. Plants of the new Calylophus have larger flowers than plants of the parent selection.
- 3. Flowers of plants of the new Calylophus are lighter yellow in color than flowers of plants of the parent selection.

Plants of the new Calylophus can be compared to plants of Calylophus hybrida ‘WNCYLASUN’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons, plants of the new Calylophus differ primarily from plants of ‘WNCYLASUN’ in flower color as plants of the new Calylophus have lighter yellow-colored flowers than plants of ‘WNCYLASUN’.

Plants of the new Calylophus can be compared to plants of Calylophus drummondianus ‘Southern Belle’, not patented. In side-by-side comparisons, plants of the new Calylophus differ primarily from plants of ‘Southern Belle’ in the following characteristics:

- 1. Plants of the new Calylophus are more vigorous than plants of ‘Southern Belle’.
- 2. Plants of the new Calylophus flower for a longer period of time than plants of ‘Southern Belle’.
- 3. Plants of the new Calylophus have larger flowers than plants of ‘Southern Belle’.
- 4. Flowers of plants of the new Calylophus are held above and beyond the foliage whereas flowers of plants of ‘Southern Belle’ are held within the foliar plane.
- 5. Flowers of plants of the new Calylophus are lighter yellow in color than flowers of plants of ‘Southern Belle’.

Plants of the new Calylophus can also be compared to plants of Oenothera hybrida ‘INNOENO131’, disclosed in U.S. Plant Pat. No. 16,393. In side-by-side comparisons, plants of the new Calylophus differ primarily from plants of ‘INNOENO131’ in the following characteristics:

- 1. Leaves of plants of the new Calylophus have entire margins with shallow and widely-space serrations whereas leaves of plants of ‘INNOENO131’ are entire.
- 2. Plants of the new Calylophus have larger flowers than plants of ‘INNOENO131’.
- 3. Flowers of plants of the new Calylophus are lighter yellow in color than flowers of plants of ‘INNOENO131’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘WNCYLALEM’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical flowering plant of ‘WNCYLALEM’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late summer and early autumn in 10.8-cm containers in a corrugated polycarbonate-covered greenhouse in Carlton, Mich. and under cultural practices typical of commercial Calylophus production. During the production of the plants, day temperatures averaged 26° C., night temperatures averaged 20° C. and light levels averaged 9,290 foot-candles. Plants were pinched three weeks after planting and were ten weeks from planting rooted cuttings when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
