USPP27669P3 - Lobularia plant named ‘DLOBUBPINK’ - Google Patents

Abstract

A new and distinct Lobularia cultivar named ‘DLOBUBPINK’ is disclosed, characterized by long lasting light lavender-pink flowers, semi-trailing and freely branching form, with good vigor and strong structure. The new variety is a Lobularia, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Lobularia maritima.

Variety denomination: ‘DLOBUBPINK’.

BACKGROUND OF THE INVENTION

The new Lobularia cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Lobularia varieties for ornamental commercial applications. The open pollination resulting in this new variety was made during March of 2012.

The seed parent is the, unpatented, proprietary variety referred to as Lobularia ‘AY-12-414’. The pollen parent is unknown as it was an open pollination breeding program. The new variety was discovered in January of 2013 by the inventor in a group of seedlings resulting from the 2012 crossing, in a research greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar was performed by vegetative cuttings. This was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel in March of 2013 and has shown that the unique features of this cultivar are stable and reproduced true to type in more than 10 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DLOBUBPINK’ 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 ‘DLOBUBPINK’ These characteristics in combination distinguish ‘DLOBUBPINK’ as a new and distinct Lobularia cultivar:

• • 1. Light lavender-pink color.
  • 2. Semi-trailing and vigor plant habit.
  • 3. Freely branching plants with a strong structure.
  • 4. Long flowering period.

Plants of the new cultivar ‘DLOBUBPINK’ are similar to plants of the seed parent, Lobularia ‘AY-12-414’ in most horticultural characteristics, however, plants of the new cultivar ‘DLOBUBPINK’ differ in the following;

• • 1. Plants habit is more round, mounded and controlled. The parent habit is loose, open and irregular.
  • 2. More floriferous.
  • 3. Smaller flowers.
  • 4. Flowers are light lavender-pink, while the flowers of the seed parent are lavender.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DLOBUBPINK’ are comparable to the patented commercial variety Lobularia ‘INLBUBLUPR’ U.S. Plant Pat. No. 25,516. The two Lobularia varieties are similar in most horticultural characteristics; however, the new variety ‘DLOBUBPINK’ differs in the following:

• • 1. Wider leaves.
  • 2. Flower color—plants of candidate variety has light pink-lilac flowers while flowers of the variety ‘INLBUBLUPR’ are light violet.
  • 3. Semi trailing and denser form.

Plants of the new cultivar ‘DLOBUBPINK’ can also be comparable to the unpatented commercial variety Lobularia ‘Snow Princess’. The two Lobularia varieties are similar in most horticultural characteristics; however, the new variety ‘DLOBUBPINK’ differs in the following:

• • 1. New variety is semi trailing and less vigorous.
  • 2. New variety has smaller leaves.
  • 3. New variety has shorter and tighter inflorescences.
  • 4. New variety is not sterile, whereas plants of ‘Snow Princess’ are.
  • 5. New variety has smaller flowers

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DLOBUBPINK’ grown in a greenhouse, in a 13 cm pot. Age of the plant photographed is approximately 7 weeks from sticking.

FIG. 2 illustrates a close up of the foliage.

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.
