Abstract

A new and distinct cultivar of Crossandra plant named ‘Docroswat’, characterized by its compact, upright to outwardly spreading plant habit; moderately vigorous and moderate growth rate; freely branching habit; dense and bushy plant form; freely flowering habit; reddish orange-colored flowers; and good garden performance.

Description

Botanical designation: Crossandra infundibuliformis.

Cultivar denomination: ‘DOCROSWAT’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Crossandra plant, botanically known as Crossandra infundibuliformis, and hereinafter referred to by the name ‘Docroswat’.

The new Crossandra plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program is to create new compact and freely-branching Crossandra plants with numerous attractive flowers.

The new Crossandra plant originated from an open-pollination in September, 2018 in De Lier, The Netherlands of Crossandra infundibuliformis ‘Nile Queen’, not patented, as the female, or seed, parent with an unknown selection of Crossandra infundibuliformis as the male, or pollen, parent. The new Crossandra plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in De Lier, The Netherlands in July, 2019.

Asexual reproduction of the new Crossandra plant by terminal cuttings in a controlled greenhouse environment in De Lier, The Netherlands since July, 2019 has shown that the unique features of this new Crossandra plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Crossandra 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 ‘Docroswat’. These characteristics in combination distinguish ‘Docroswat’ as a new and distinct Crossandra plant:

- 1. Compact, upright to outwardly spreading plant habit.
- 2. Moderately vigorous and moderate growth rate.
- 3. Freely branching habit; dense and bushy plant form.
- 4. Freely flowering habit.
- 5. Reddish orange-colored flowers.
- 6. Good garden performance.

Plants of the new Crossandra can be compared to plants of the female parent selection. Plants of the new Crossandra differ primarily from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Crossandra are more compact than plants of the female parent selection.
- 2. Plants of the new Crossandra have shorter internodes than plants of the female parent selection.
- 3. Leaves of plants of the new Crossandra are glossier than leaves of plants of the female parent selection.
- 4. Flowers of plants of the new Crossandra are reddish orange in color whereas flowers of plants of the female parent selection are red in color.

Plants of the new Crossandra can be compared to plants of Crossandra infundibuliformis ‘Orange Marmalade’, not patented. In side-by-side comparisons, plants of the new Crossandra differ primarily from plants of ‘Orange Marmalade’ in flower color as flowers of plants of the new Crossandra are reddish orange in color whereas flowers of plants of ‘Orange Marmalade’ are orange in color. In addition, leaves of plants of the new Crossandra are lighter green in color than leaves of plants of ‘Orange Marmalade’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Crossandra plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Crossandra plant. The photograph is a side perspective view of a typical flowering plant of ‘Docroswat’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the summer in 12-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under cultural practices typical of commercial Crossandra production. During the production of the plants, day temperatures ranged from 20° C. to 35° C. and night temperatures ranged from 17° C. to 25° C. Plants were pinched one time about five weeks after sticking unrooted cuttings. Plants were 14 weeks old when the photograph was taken and twelve weeks old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
