plant named ‘Dolce Vita’

Abstract

A new and distinct cultivar of Lonicera plant named ‘Dolce Vita’, characterized by its upright and outwardly spreading plant habit; vigorous growth habit and rapid growth rate; early and freely fruiting habit; large flavorful dark blue-colored fruits; and good garden performance.

Description

Botanical designation: Lonicera caerulea var. Kamtschatica.

Cultivar denomination: ‘DOLCE VITA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lonicera plant, botanically known as Lonicera caerulea var. Kamtschatica, commonly referred to as Honeysuckle and hereinafter referred to by the name ‘Dolce Vita’.

The new Lonicera is a product of a planned breeding program conducted by the Inventor in Vl{hacek over (c)}kov, Czech Republic. The objective of the breeding program was to develop new early fruiting Lonicera plants with large and flavorful fruits.

The new Lonicera plant originated from a cross-pollination conducted by the Inventor in May, 1998 of two unnamed seedling selections of Lonicera caerulea var. Kamtschatica, not patented. The new Lonicera plant was discovered and selected by the Inventor in June, 2001 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Vl{hacek over (c)}kov, Czech Republic.

Asexual reproduction of the new Lonicera plant by softwood cuttings in a controlled greenhouse environment in Vl{hacek over (c)}kov, Czech Republic since July, 2010 has shown that the unique features of this new Lonicera plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Lonicera have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Dolce Vita’. These characteristics in combination distinguish ‘Dolce Vita’ as a new and distinct Lonicera plant:

• • 1. Upright and outwardly spreading plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Early and freely fruiting habit.
  • 4. Large flavorful dark blue-colored fruits.
  • 5. Good garden performance.

Plants of the new Lonicera can be compared to plants of the female parent selection. In side-by-side comparisons, plants of the new Lonicera differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Lonicera are larger and more vigorous than plants of the female parent selection.
  • 2. Plants of the new Lonicera have larger leaves than plants of the female parent selection.
  • 3. Plants of the new Lonicera produce more fruits than plants of the female parent selection.
  • 4. Fruits of plants of the new Lonicera are larger, more flavorful and more persistent than fruits of plants of the female parent selection.

Plants of the new Lonicera can be compared to plants of the male parent selection. In side-by-side comparisons, plants of the new Lonicera differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Lonicera produce more fruits than plants of the male parent selection.
  • 2. Fruits of plants of the new Lonicera are more flavorful and more persistent than fruits of plants of the male parent selection.

Plants of the new Lonicera can be compared to plants of Lonicera caerulea ‘Amur’, not patented. In side-by-side comparisons plants of the new Lonicera differed primarily from plants of ‘Amur’ in the following characteristics:

• • 1. Plants of the new Lonicera were larger than plants of ‘Amur’.
  • 2. Fruits of plants of the new Lonicera were larger, more flavorful and more persistent than fruits of plants of ‘Amur’.

Plants of the new Lonicera can be compared to plants of Lonicera caerulea ‘Altaj’, not patented. In side-by-side comparisons plants of the new Lonicera differed primarily from plants of ‘Altaj’ in the following characteristics:

• • 1. Plants of the new Lonicera were larger than plants of ‘Altaj’.
  • 2. Plants of the new Lonicera fruited later than plants of ‘Altaj’.
  • 3. Fruits of plants of the new Lonicera were larger, more flavorful and more persistent than fruits of plants of ‘Amur’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in three-gallon containers and ground beds during the spring in a polyethylene-covered greenhouse in Grand Haven, Mich. and under cultural practices typical of commercial Lonicera production. During the production of the plants, day temperatures ranged from 20° C. to 32° C. and night temperatures ranged from 12° C. to 20° C. Plants were one year old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
