Abstract

A new cultivar of Symphoricarpos plant named ‘KOLMASYWHI’ that is characterized by its short branches, its white berries, and its suitability for use as a container plant.

Description

Botanical classification: Symphoricarpos x doorenbosii.

Variety denomination: ‘KOLMASYWHI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Symphoricarpos x doorenbosii that will be referred to hereafter by its cultivar name, ‘KOLMASYWHI’. The new cultivar represents a new cultivar of snowberry or coralberry that is used as a landscape and container plant.

The new Invention arose from an ongoing controlled breeding program in Heelsum, The Netherlands. The objective was to elect a new cultivar of Symphoricarpos with white berries, short branches and a compact plant habit that is suitable for growing in containers. The new cultivar arose from open pollination in August of 2012 of an unnamed and unpatented proprietary plant in the Inventor's breeding program, reference no. 10-27, as the female parent. The male parent is therefore unknown. ‘KOLMASYWHI’ was selected from amongst the resulting seedlings as a single unique plant in October of 2015.

Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor using softwood stem cuttings in November of 2015 in Boskoop, The Netherlands. Asexual propagation by softwood stem cuttings 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 ‘KOLMASYWHI’ as a new and unique cultivar of Symphoricarpos.

• • 1. ‘KOLMASYWHI’ exhibits short branches.
  • 2. ‘KOLMASYWHI’ exhibits white berries.
  • 3. ‘KOLMASYWHI’ exhibits suitability for use as a container plant.

The female parent of ‘KOLMASYWHI’ differs from ‘KOLMASYWHI’ in having a longer branches and side shoots, and weaker branches. ‘KOLMASYWHI’ can be most closely compared to the Symphoricarpos cultivars ‘Kolmava’ (not patented) and ‘Kolmawhidre’ (not patented). ‘Kolmava’ and ‘Kolmawhidre’ are both similar to ‘KOLMASYWHI’ in having white berries. ‘Kolmava’ and ‘Kolmawhidre’ both differ from ‘KOLMASYWHI’ in having much longer branches.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Symphoricarpos 3 years in age as grown outdoors in a 3-gallon container in Dayton, Oreg.

The photograph in FIG. 1 provides a view of the plant habit of ‘KOLMASYWHI’.

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 Symphoricarpos.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 3-year-old plants of the new Symphoricarpos as grown outdoors in a 3-gallon container in Dayton, Oreg.
