plant named ‘Jsahti’

Abstract

A new and distinct cultivar of Limonium plant named ‘Jsahti’, characterized by its erect, strong and medium in length flowering stems; freely flowering habit; short flowering cycle; relatively small flowers with white-colored persistent calyces; and excellent postproduction longevity.

Description

Botanical designation: Limonium sinense.

Cultivar denomination: ‘JSAHTI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Limonium plant, botanically known as Limonium sinense, commercially used as a cut flower Limonium, and hereinafter referred to by the name ‘Jsahti’.

The new Limonium plant is a product of a planned breeding program in Madrid, Cundinamarca, Colombia. The objective of the breeding program is to create new high-yielding Limonium cultivars that have a short forcing cycle and that are resistant to pathogens.

The new Limonium plant originated from an open-pollination in Madrid, Cundinamarca, Colombia in December, 2004 of a proprietary selection of Limonium sinense identified as code number JS 401001-3, not patented, as the female, or seed, parent with an unknown selection of Limonium sinense as the male, or seed, parent. The new Limonium plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated open-pollination grown in a controlled environment in Madrid, Cundinamarca, Colombia on Jul. 4, 2005.

Asexual reproduction of the new Limonium plant since February, 2006 by tissue culture in a controlled environment in Madrid, Cundinamarca, Colombia has shown that the unique features of this new Limonium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Limonium have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature 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 ‘Jsahti’. These characteristics in combination distinguish ‘Jsahti’ as a new and distinct cultivar of Limonium plant:

• • 1. Erect, strong and medium in length flowering stems.
  • 2. Freely flowering habit.
  • 3. Short flowering cycle.
  • 4. Relatively small flowers with white-colored persistent calyces.
  • 5. Excellent postproduction longevity.

Plants of the new Limonium can be compared to plants of the female parent selection. Plants of the new Limonium differ primarily from plants of the female parent selection in yield as plants of the new Limonium produce more flowering stems than plants of the female parent selection. In addition, plants of the new Limonium and the female parent selection differ in flower color.

Plants of the new Limonium can be compared to plants of Limonium sinense ‘Silver Diamond’, not patented. In side-by-side comparisons conducted in Madrid, Cundinamarca, Colombia, plants of the new Limonium differed primarily from plants of ‘Silver Diamond’ in the following characteristics:

• • 1. Plants of the new Limonium had shorter flowering stems than plants of ‘Silver Diamond’.
  • 2. Plants of the new Limonium were more freely flowering than plants of ‘Silver Diamond’.
  • 3. Plants of the new Limonium had smaller flowers than plants of ‘Silver Diamond’.
  • 4. Plants of the new Limonium had a shorter flowering cycle than plants of ‘Silver Diamond’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants of the new Limonium grown in Madrid, Cundinamarca, Colombia in a polyethylene-covered greenhouse in ground beds. During the production of the plants, day temperatures ranged from 15° C. to 25° C., night temperatures ranged from 8° C. to 12° C. and light levels averaged 21.4 KWH/m². Plants were pinched one time about six weeks after planting. Plants were 17 weeks old when the photographs and description were taken. Color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
