plant named ‘On The Red’

Abstract

A new cultivar of Arctotis, ‘On The Red’, characterized by its compact and dense growth habit, its strong and short flowering stems, its large number of ray florets, its continuous blooming habit, and its dark red ray florets with a yellow base creating a ring of yellow near the center of the inflorescences.

Description

Botanical classification: Arctotis acaulis.

Variety denomination: ‘On The Red’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Arctotis acaulis and will be referred to hereafter by its cultivar name, ‘On The Red’. ‘On The Red’ represents a new herbaceous perennial grown for container and landscape use.

The new cultivar, ‘On The Red’, was discovered as a whole plant mutation in a nursery plot by the Inventor in George, South Africa in spring of 2006. The nursery plot was planted with various unpatented cultivars and unnamed plants of Arctotis acaulis that were being evaluated for breeding potential. ‘On The Red’ arose as a seedling from open pollination and the parentage is unknown.

Asexual reproduction of the new cultivar was first accomplished by stem cuttings by the Inventor in 2007 in George, South Africa. Propagation by stem cutting and in vitro propagation has determined that the characteristics of this cultivar are stable and are 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 ‘On The Red’ as a unique cultivar of Arctotis.

• • 1. ‘On The Red’ exhibits a compact growth habit with sturdy, well-branched stems and dense foliage.
  • 2. ‘On The Red’ exhibits a floriferous blooming habit, continuously producing flowers during the growing season.
  • 3. ‘On The Red’ exhibits inflorescences with a large number of ray florets.
  • 4. ‘On The Red’ exhibits flowering stems that are short in height.
  • 5. ‘On The Red’ exhibits inflorescences with ray florets that are dark red in color with a yellow base creating an inner yellow ring in the center of the inflorescence.

The new Arctotis is unique in comparison to other species and cultivars of Arctotis known to the Inventor. ‘On The Red’ differs from the selections in the research plot in having shorter flowering stems, a more compact growth habit, a larger number of ray florets, and in having dark red ray florets. ‘On The Red’ can be most closely compared to the cultivars ‘Sunset Radiance’ and ‘Radiance Red’ (both unpatented). They are both similar to ‘On The Red’ in leaf color and flower type. However, they both differ from ‘On The Red’ in having less compact growth habits, longer flowering stems, and fewer ray florets per bloom. In addition, ‘Sunset Radiance’ differs in having ray florets that are orange in color and ‘Radiance Red’ differs in having ray florets that are lighter red in color.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of nine month-old plants of the new cultivar as grown in a greenhouse in one-gallon containers in Grand Saline, Tex. 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 The 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
