plant named ‘Kolmaswet’

Abstract

A new and distinct cultivar of Symphoricarpos plant named ‘Kolmaswet’, characterized by its compact, upright and outwardly spreading plant habit; short stems and internodes, bushy and dense habit; freely flowering habit; numerous red purple-colored berries; and good garden performance.

Description

Botanical designation: Symphoricarpos alba.

Cultivar denomination: ‘Kolmaswet’.

BACKGROUND OF THE INVENTION

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

The new Symphoricarpos plant is a product of a planned breeding program conducted by the Inventor in Heelsum, The Netherlands. The objective of the breeding program is to create new pot-type Symphoricarpos cultivars with strong foliage and numerous attractive fruits.

The new Symphoricarpos plant originated from a cross-pollination in 2001 in Heelsum, The Netherlands of a proprietary selection of Symphoricarpos alba identified as code number 99-23, not patented, as the female, or seed parent with a proprietary selection of Symphoricarpos alba identified as code number 00-17, not patented, as the male, or pollen, parent. The new Symphoricarpos was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heelsum, The Netherlands in 2003.

Asexual reproduction of the new Symphoricarpos plant by vegetative cuttings in Boskoop, The Netherlands since 2003 has shown that the unique features of this new Symphoricarpos plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Symphoricarpos have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Kolmaswet’. These characteristics in combination distinguish ‘Kolmaswet’ as a new and distinct cultivar of Symphoricarpos:

• • 1. Compact, upright and outwardly spreading plant habit.
  • 2. Short stems and internodes, bushy and dense habit.
  • 3. Freely flowering habit.
  • 4. Numerous red purple-colored berries.
  • 5. Good garden performance.

Plants of the new Symphoricarpos differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Symphoricarpos have shorter lateral branches than plants of the female parent selection.
  • 2. Plants of the new Symphoricarpos and the female parent selection differ in fruit color as plants of the female parent selection have white-colored berries.

Plants of the new Symphoricarpos differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Symphoricarpos have shorter lateral branches than plants of the male parent selection.
  • 2. Plants of the new Symphoricarpos have stronger lateral branches than plants of the male parent selection.

Plants of the new Symphoricarpos can be compared to plants of Symphoricarpos ‘Scarlet Pearl’, disclosed in U.S. Plant Pat. No. 13,244. Plants of the new Symphoricarpos differ primarily from plants of ‘Scarlet Pearl’ in plant habit as plants of the new Symphoricarpos are more compact and denser than plants of ‘Scarlet Pearl’.
