Abstract

A distinct cultivar of Arctotis plant named ‘Archnah’, characterized by its compact, upright and mounded plant habit; freely branching growth habit; and orange red-colored ray florets and nearly black-tipped disc florets with orange-colored pollen.

Description

Botanical classification/cultivar designation: Arctotis×hybrida cultivar Archnah.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Arctotis plant, botanically known as Arctotis×hybrida, and hereinafter referred to by the name ‘Archnah’.
The new Arctotis is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program is to create new compact Arctotis cultivars that flower early and have interesting floret colors.
The new Arctotis originated from a cross made by the Inventor in 1998 of the Arctotis×hybrida cultivar Flame, not patented, as the female, or seed, parent with the Arctotis×hybrida cultivar Silver Carpet, not patented, as the male, or pollen, parent. The new Arctotis was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Cobbitty, New South Wales, Australia, in May, 1999.
Asexual reproduction of the new Arctotis by terminal vegetative cuttings was first conducted in Cobbitty, New South Wales, Australia in May, 1999. Asexual reproduction by cuttings has shown that the unique features of this new Arctotis are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Archnah has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Archnah’. These characteristics in combination distinguish ‘Archnah’ as a new and distinct Arctotis:
1. Compact, upright and mounded plant habit.
2. Freely branching growth habit.
3. Orange red-colored ray florets and nearly black-tipped disc florets with orange-colored pollen.
Plants of the new Arctotis are most similar to plants of the female parent, the cultivar Flame. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Arctotis differed from plants of the cultivar Flame in the following characteristics:
1. Plants of the new Arctotis were more compact than plants of the cultivar Flame.
2. Flowers of plants of the new Arctotis had orange red-colored ray florets whereas flowers of plants of the cultivar Flame had orange-colored ray florets.
Plants of the new Arctotis can also be compared to plants of the male parent, the cultivar Silver Carpet. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Arctotis differed from plants of the cultivar Silver Carpet in the following characteristics:
1. Plants of the new Arctotis were more upright than and not as spreading as plants of the cultivar Silver Carpet.
2. Leaves of plants of the new Arctotis were green in color whereas leaves of plants of the cultivar Silver Carpet were gray in color.
3. Flowers of plants of the new Arctotis had orange red-colored ray florets whereas flowers of plants of the cultivar Silver Carpet had pink-colored ray florets.
Plants of the new Arctotis differ from plants of the cultivar Archley, disclosed in a U.S. Plant Patent application filed concurrently, primarily in plant size, branching habit, leaf color and ray floret color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Arctotis showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Arctotis.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Archnah’ grown in a 15-cm container.
The photograph at the bottom of the sheet is a close-up view of typical inflorescences of ‘Archnah’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Bonsall, Calif., in an outdoor nursery during the late spring and early summer under full sun conditions with day temperatures ranging from 18 to 35° C. and night temperatures ranging from 7 to 18° C. After planting rooted cuttings, plants were grown for about six to eight weeks in 15-cm containers. Color references are made to The Royal Horticultural Society Colour Chart, 1995 edition, except where general terms of ordinary dictionary significance are used.
