Description

Latin name of the genus and species: Lobularia maritime.

Variety denomination: ‘DLOBRASTRM’.

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 proprietary variety referred to as Lobularia ‘AY-13-558’. The pollen parent is unknown as it was an open pollination breeding program. The new variety was discovered in February of 2014 by the inventor in a group of seedlings resulting from the April 2013 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 February of 2014 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 ‘DLOBRASTRM’ 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 ‘DLOBRASTRM’ These characteristics in combination distinguish ‘DLOBRASTRM’ as a new and distinct Lobularia cultivar:

    • 1. Compact and semi-trailing habit
    • 2. Long flowering period.
    • 3. Free branching.
    • 4. Dark red-purple flower color.

Plants of the new cultivar ‘DLOBRASTRM’ are similar to plants of the seed parent, Lobularia ‘AY-13-558’ in most horticultural characteristics, however, plants of the new cultivar ‘DLOBRASTRM’ differ in the following;

    • 1. Plants of the new variety are bushier than plants of the female parent.
    • 2. Plants of the new variety are more floriferous than plants of the female parent.
    • 3. Plants of the new variety have better heat tolerance than plants of the female parent.
    • 4. Plants of the new variety flower for a longer period than plants of the female parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DLOBRASTRM’ are comparable to the patented commercial variety Lobularia ‘INLBUBLUPR’. U.S. Plant Pat. No. 24,516. The two Lobularia varieties are similar in most horticultural characteristics; however, the new variety ‘DLOBRASTRM’ differs in the following:

    • 1. Plants of the new variety are more compact and dense than plants of ‘INLBUBLUPR’.
    • 2. Plants of the new variety are less cold sensitive than plants of ‘INLBUBLUPR’.
    • 3. Plants of the new variety have shorter and tighter inflorescences than plants of ‘INLBUBLUPR’.
    • 4. Plants of new variety have red-purple flowers; flowers of “INLBUBLUPR’ are purple and white.

Plants of the new cultivar ‘DLOBRASTRM’ can also be comparable to the unpatented commercial variety Lobularia ‘DLOBUBPINK’, U.S. Plant Pat. No. 27,669. The two Lobularia varieties are similar in most horticultural characteristics; however, the new variety ‘DLOBRASTRM’ differs in the following:

    • 1. Plants of the new variety produce dark pink flowers; flowers of ‘DLOBUPINK’ are light pink.
    • 2. Plants of new variety have a more compact and moderate trailing habit than plants of ‘DLOBUPINK’.
    • 3. Plants of new variety are less vigorous than plants of ‘DLOBUPINK’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DLOBRASTRM’ grown in a greenhouse, in a 13 cm pot. Age of the plant photographed is approximately 8 weeks from an unrooted cutting.

FIG. 2 illustrates a close up of the flowers.

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.
