Limonium plant named ‘Danlisablue’

Abstract

A new and distinct Limonium plant named ‘Danlisablue’ particularly characterized by the combination of violet-blue flower color, RHS 93 B; high stems measuring 70-90 cm; panicle branching habit; flexible stems; and a yield of 6-10 stems per plant in the first flash.

Description

Latin name of the genus and species of the claimed plant: Limonium altaica.

Variety denomination: ‘Danlisablue’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Limonium plant, botanically known as Limonium altaica, hereinafter referred to by the variety denomination ‘Danlisablue’.

Limonium of the Plumbaginaceae family, is commonly known as sealavender. Limonium is found wild on sea coasts and marshes across the Northern Hemisphere.

The new cultivar originated from an open pollination of Limonium plants within a breeding program field, discovered in a controlled environment in Moshav Mishmar Hashiva, Israel. The female parent is proprietary cultivar designated ‘PTE’ (unpatented). The male parent is unknown. ‘Danlisablue’ was discovered and selected by the inventor, Gabriel Danziger, as a flowering plant within the progeny of the open pollination program in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar by tissue culture was first performed in August, 2001, in Moshav Mishmar Hashiva, Israel, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true-to-type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Danlisablue’ which in combination distinguish this Limonium as a new and distinct cultivar:

• • 1. violet-blue flower color, RHS 93 B;
  • 2. high stems measuring 70-90 cm;
  • 3. panicle branching habit;
  • 4. flexible stems; and
  • 5. yield of 6 to 10 stems per plant in the first flash.

‘Danlisablue’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and daylength without any change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in Moshav Mishmar Hashiva, Israel under conditions which closely approximate those generally used in commercial practice.

Table 1 provides a comparison between plants of ‘Danlisablue’ and plants of the parent, ‘PTE’ (unpatented).

Of the many commercial cultivars known to the inventor, the most similar in comparison to ‘Danlisablue’ is the cultivar ‘Tall Emille’ (unpatented). In comparison to ‘Tall Emille’, ‘Danlisablue’ has flexible stems whereas ‘Tall Emille’ has durable stems, and ‘Danlisablue’ has a narrow shaped inflorescence and panicle branching habit while ‘Tall Emille’ has an open and wide shaped inflorescence.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the overall appearance of the new Limonium showing the colors as true as is reasonably possible with color reproductions of this type. The first photograph shows a top view of a flowering ‘Danlisablue’ plant. The second photograph shows a side view of a flowering ‘Danlisablue’ plant.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe the new cultivar as grown in Moshav Mishmar Hashiva, Israel, in Mediterranean climate at sea level, under conditions which closely approximate those generally used in commercial practice. Irrigation and fertilization use is common to commercial practice for Limonium.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S) (published 2001) except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 10:00 AM in Moshav Mishmar Hashiva, Israel. The age of the plant described was 1 year old, in its second flash and the stem which used to determine the R.H.S colour was at 30-50% open flower stage.
