plant named ‘Jsada’

Abstract

A new and distinct cultivar of Limonium plant named ‘Jsada’, characterized by its erect, long and strong flowering stems; relatively large leaves; freely flowering habit; small white-colored flowers arranged in narrow inflorescences; and excellent postproduction longevity.

Description

Botanical designation: Limonium sinense.

Cultivar Denomination: ‘Jsada’.

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 ‘Jsada’.

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

The new Limonium plant originated from an open-pollination in Madrid, Cundinamarca, Colombia in February, 2006 of a proprietary selection of Limonium sinense identified as code number JS401003-3, 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 greenhouse environment in Madrid, Cundinamarca, Colombia on Oct. 24, 2006.

Asexual reproduction of the new Limonium plant by cuttings in a controlled greenhouse environment in Madrid, Cundinamarca, Colombia since February, 2007, 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 ‘Jsada’. These characteristics in combination distinguish ‘Jsada’ as a new and distinct cultivar of Limonium plant:

• • 1. Erect, long and strong flowering stems.
  • 2. Relatively large leaves.
  • 3. Freely flowering habit.
  • 4. Small white-colored flowers arranged in narrow inflorescences.
  • 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 from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Limonium produced more flowering stems than plants of the female parent selection.
  • 2. Plants of the new Limonium and the female parent selection differed in flower color as plants of the female parent selection had pink-colored flowers.

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 straighter flowering stems than plants of ‘Silver Diamond’.
  • 2. Plants of the new Limonium had larger and flatter leaves than plants of ‘Silver Diamond’.
  • 3. Plants of the new Limonium had lighter green-colored flowering stems than plants of ‘Silver Diamond’.
  • 4. Inflorescences of plants of the new Limonium were not as open as inflorescences of plants of ‘Silver Diamond’.
  • 5. Flowers of plants of the new Limonium were positioned towards the apex of the flowering stems whereas flowers of plants of ‘Silver Diamond’ were positioned in the upper half of the flowering stems.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants of the new Limonium grown in ground beds in a polyethylene-covered greenhouse located in Madrid, Cundinamarca, Colombia. 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 per week. Plants were pinched one time about six weeks after planting and were 18 weeks old when the description and photographs 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.
