USPP34517P2 - Iberis plant named ‘DIBFRFLAL’ - Google Patents

Abstract

A new and distinct variety of Iberis plant named ‘DIBFRFLAL’ is disclosed, characterized by a controlled and mounded plant habit. Plants produce abundant light lavender colored flowers in the first year. Vernalization is not required for flowering. The new variety is an Iberis, useful for ornamental horticulture purposes.

Description

Latin name of the genus and species: Iberis sempervirens.

Variety denomination: ‘DIBFRFLAL’.

BACKGROUND OF THE INVENTION

The new Iberis cultivar is a product of a planned breeding program. The new variety was discovered as a seedling resulting from an open-pollination breeding program at a research greenhouse in Moshav Mishmar Hashiva, Israel during Spring of 2016. The interesting new variety was discovered during the Spring of 2017.

The seed parent is the unpatented, proprietary variety ‘IB-13-260’. The pollen parent is unknown.

Asexual reproduction of the new cultivar has been performed by terminal vegetative cuttings. This was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel during the Spring of 2017 and has shown that the unique features of this cultivar are stable and reproduced true to type in more successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DIBFRFLAL’ 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 ‘DIBFRFLAL’ These characteristics in combination distinguish ‘DIBFRFLAL’ as a new and distinct Iberis cultivar:

• • 1. First year flowering.
  • 2. Vernalization is not required for flowering.
  • 3. Controlled plant growth with a mounded habit.
  • 4. Light lavender flowers.

PARENTAL COMPARISON

Plants of the new cultivar ‘DIBFRFLAL’ are are similar to the seed parent in most horticultural characteristics. The new variety ‘DIBFRFLAL’ differs in the following:

• • 1. The new variety flowers earlier than the seed parent.
  • 2. The hew variety has a more compact plant habit.
  • 3. The new variety has a mounded plant habit; the seed parent has a spreading plant habit.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DIBFRFLAL’ are comparable to the unpatented commercial variety Iberis ‘Snowsurfer’. The two Iberis varieties are similar in most horticultural characteristics; however, the new variety ‘DIBFRFLAL’ differs in the following:

• • 1. Plants of the new variety are not observed to produce seeds; plants of this comparator are observed to produce seeds, which should result in a shorter life span.
  • 2. The new variety has a mounded plant habit; this comparator has an upright plant habit.
  • 3. Flowers of the new variety are light lavender; flowers of this comparator are white.

Plants of the new cultivar ‘DIBFRFLAL’ can also be compared to the unpatented commercial variety Iberis ‘Snow Cushion’. The two Iberis varieties are similar in most horticultural characteristics; however, the new variety ‘DIBFRFLAL’ differs in the following:

• • 1. Plants of the new variety flower earlier than plants of this comparator.
  • 2. Plants of the new variety are dense and mounding; plants of this comparator are less dense and flattened, trailing.
  • 3. Flowers of the new variety are light lavender; flowers of this comparator are white.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical flowering plant of ‘DIBFRFLAL’ in a 20 cm pot at approximately 20 weeks from a rooted cutting.

FIG. 2 illustrates a close up of flowers of the new variety.

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.
