USPP29319P2 - Convolvulus plant named ‘Blue Moon’ - Google Patents

Abstract

A new and distinct Convolvulus cultivar named ‘BLUE MOON’ is disclosed, characterized by mounding, densely growing plants. Flowers are dark Violet-Blue. The new variety is a Convolvulus, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Convolvulus hybrida.

Variety denomination: ‘BLUE MOON’.

BACKGROUND OF THE INVENTION

The new Convolvulus cultivar is a product of a planned breeding program, conducted by the inventor, Steve Eggleton, in Wonga Park, Victoria, Australia. The objective of the breeding program was to develop new varieties of Convolvulus with compact habits and abundant flowering for commercial ornamental horticultural purposes.

The inventor created an open-pollination breeding program using multiple sources con Convolvulus species, including selections from uncultivated populations, landrace varieties or unnamed plants as well as heterogeneous material. The seed parent is the unpatented Convolvulus ‘Two Moons’. The open-pollination resulting in the new variety occurred during March of 2013. The final selection of this new variety was made November 2014.

Asexual reproduction of the new cultivar was first performed by vegetative stem cuttings. at the same commercial greenhouse in Wonga Park, Australia in November of 2014. Subsequent propagation and growing the plants over a period of several months show the unique characteristics of the new variety to be stable over multiple propagative generations. Plants were first made available to the public Mar. 1, 2016. All plant material made public was originally derived from the inventor.

SUMMARY OF THE INVENTION

The cultivar ‘BLUE MOON’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘BLUE MOON’ These characteristics in combination distinguish ‘BLUE MOON’ as a new and distinct Convolvulus cultivar:

• • 1. Dense plants.
  • 2. Mounding plant form.
  • 3. Abundant dark Violet-Blue flowers.

PARENT COMPARISON

Plants of the new cultivar ‘Blue Moon’ are similar to plants of ‘Two Moons’ in most horticultural characteristics, however, plants of the new variety differ in the following:

• • 1. Plants of the new variety are dense, plants of the seed parent variety are sparse.
  • 2. Plant form of the new variety is mounding, plant form of the seed parent is flattened and spreading.
  • 3. Flower color of the new variety is dark Violet-Blue, flower color of the seed parent is white to lavender.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘BLUE MOON’ can also be comparable to the patented Convolvulus sabatius. ‘Moroccan Beauty’, U.S. Plant Pat. No. 15,104 The two Convolvulus varieties are similar in most horticultural characteristics; however, the new variety differs in the following:

• • 1. Plant habit of the new variety is mounding, plant habit of this comparator is flat and spreading.
  • 2. Plants of the new variety are denser than plants of this comparator.
  • 3. Flower color of the new variety is darker than that of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘BLUE MOON’ grown outdoors in Wonga Park, Australia in a 1 liter container. Age of the plant photographed is approximately 20 weeks from a rooted cutting.

FIG. 2 illustrates several plants of the new variety, grown in liter containers under commercial conditions in Wonga Park, Australia.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
