plant named ‘DSAM13-1’

Abstract

A new cultivar of Delosperma plant, ‘DSAM13-1’, that is characterized by its compact and very horizontal plant habit, its relatively small leaves, its very floriferous and long blooming flowering habit, and its flowers with petals that are bright red purple in color at the apex and lighter red-purple near the base, petaloids that are white with purple tips, and anthers that are yellow.

Description

Botanical classification: Delosperma cooperi.

Variety denomination: ‘DSAM13-1’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is co-pending with U.S. Plant Patent Applications filed for plants derived from the same breeding program that are entitled Delosperma Plant Named ‘DSAB13-1’ (U.S. Plant patent application Ser. No. 14/544,006), Delosperma Plant Named ‘DSAA13-1’ (U.S. Plant patent application Ser. No. 14/544,004).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Delosperma plant, botanically known as Delosperma cooperi ‘DSAM13-1’ and will be referred to hereinafter by its cultivar name, ‘DSAM13-1’. The new cultivar of Delosperma is a herbaceous perennial grown for container and landscape use.

The new cultivar was derived from a controlled breeding program conducted by the Inventor in Ichinimiya-City, Aichi-Pref, Japan. The overall purpose of the breeding program was to develop new cultivars of Delosperma plants with low-growing and well-spreading growth habits combined with long flowering periods and a unique range of flower colors.

‘DSAM13-1’ was selected in the Inventor's trial garden in 2012 as a single unique plant from amongst the seedlings derived from self-crossing an unnamed and unpatented plant from the Inventor's breeding program in 2011. The Inventor's reference number for the parent plant is DSAM12-1.

Asexual propagation of the new cultivar was first accomplished by softwood cuttings in 2012 by the Inventor in Ichinimiya-City, Aichi-Pref, Japan. Asexual propagation by softwood cuttings has determined the characteristics of the new cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘DSAM13-1’ as a unique cultivar of Delosperma.

• • 1. ‘DSAM13-1’ exhibits a compact and very horizontal plant habit.
  • 2. ‘DSAM13-1’ exhibits relatively small leaves.
  • 3. ‘DSAM13-1’ exhibits a very floriferous and long blooming flowering habit.
  • 4. ‘DSAM13-1’ exhibits flowers with petals that are bright red purple in color at the apex and lighter red-purple near the base, petaloids that are white with purple tips, and anthers that are yellow.
    The parent plant of ‘DSAM13-1’, Ref. No. DSAA12-1, differs from ‘DSAM13-1’ in having flowers with petals that are lighter pink in color. ‘DSAM13-1’ can also be most closely compared to cultivars with co-pending patent applications from the same breeding program, that differ from ‘DSAM13-1’ mostly in flower color; ‘DSAB13-1’ and ‘DSAA13-1’. ‘DSAB13-1’ differs from ‘DSAM13-1’ in having flowers with petals that are lighter purple-pink in color. ‘DSAA13-1’ differs from ‘DSAM13-1’ in having flowers with petals that are red-orange in color at the apex and blending into red-purple near the base.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Delosperma. The plant in the photograph is 2 months in age as grown in a 12-cm container outdoors in Lisse, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘DSAM13-1’ in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘DSAM13-1’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘DSAM13-1’.

The 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 Delosperma.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of two month-old plants of the new cultivar as grown in 12-cm containers outdoors in Lisse, The Netherlands. 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 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
