plant named ‘Kolmsqueen’

Abstract

A new cultivar of Callicarpa plant, ‘Kolmsqueen’, that is characterized by its abundance of white berries, its compact plant habit, its berries that are large in size and borne in round clusters, and its compact plant habit.

Description

Genus/species: Callicarpa bodinieri.

Varietal denomination: ‘Kolmsqueen’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Callicarpa bodinieri and will be referred to hereafter by its cultivar name, ‘Kolmsqueen’. ‘Kolmsqueen’ represents a new cultivar of beautyberry; a deciduous shrub grown for landscape use.

The new Callicarpa arose from a breeding program conducted by the Inventor in Boskoop, The Netherlands. The objective of the breeding program was to develop new cultivar of Callicarpa with large white berries that is suitable as a garden plant.

The new Callicarpa originated from open pollination in June of 2009 of an unnamed and unpatented plant of Callicarpa from the Inventor's breeding program, designated as 715B. ‘Kolmsqueen’ was selected as a single unique plant in 2014 from the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by stem cuttings in February 2012 in Boskoop, The Netherlands under the direction of the Inventor. Asexual propagation by stem cuttings has determined that the characteristics of the new 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 Callicarpa. These attributes in combination distinguish ‘Kolmsqueen’ as a unique and distinct cultivar of Callicarpa.

• 1. ‘Kolmsqueen’ exhibits an abundance of white berries.
• 2. ‘Kolmsqueen’ exhibits berries that are large in size and borne on round clusters.
• 3. ‘Kolmsqueen’ exhibits a compact plant habit.

The female parent of ‘Kolmsqueen’ differs from ‘Kolmsqueen’ in having a less compact plant habit and berries that are purple in color. ‘Kolmsqueen’ is most closely compared to Callicarpa dichotoma ‘Albifructus’ (not patented) and Callicarpa japonica ‘Leucocarpa’ (not patented). ‘Albifructus’ is similar to ‘Kolmsqueen’ in having an upright plant habit and berries that are white in color. ‘Albifructus’ differs from ‘Kolmsqueen’ in having a less compact plant habit and berry clusters that are flattened in shape. ‘Leucocarpa’ is similar to ‘Kolmsqueen’ in having berries that are white in color. ‘Leucocarpa’ differs from ‘Kolmsqueen’ in having less berries that are smaller in size and in having less compact and a plant habit with trailing branches.
