plant named ‘Zalimsal’

Abstract

A new and distinct cultivar of Limonium plant named ‘Zalimsal’, characterized by its compact, upright and uniformly mounded plant habit; freely flowering habit; violet blue to violet-colored flowers arranged in compact inflorescences; and good garden performance.

Description

Botanical designation: Limonium puberulum×Limonium perezii.

Cultivar denomination: ‘ZALIMSAL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Limonium plant, botanically known as Limonium puberulum×Limonium perezii, commercially used as a potted Limonium, and hereinafter referred to by the name ‘Zalimsal’.

The new Limonium plant is a product of a planned breeding program in Rijsenhout, The Netherlands. The objective of the breeding program is to create new pot-type Limonium plants with uniform plant habit and unique flower coloration.

The new Limonium plant originated from a cross-pollination conducted by the Inventor in Rijsenhout, The Netherlands in August, 2007 of an unnamed selection of Limonium puberulum, not patented, as the female, or seed, parent with a selection of Limonium perezii identified as code number 60001-5, not patented, as the male, or seed, parent. The new Limonium plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment in Rijsenhout, The Netherlands in May, 2008.

Asexual reproduction of the new Limonium plant since July, 2008 by tissue culture in a controlled environment in Rijsenhout, The Netherlands 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 and cultural practices. The phenotype may vary somewhat with variations in environment 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 ‘Zalimsal’. These characteristics in combination distinguish ‘Zalimsal’ as a new and distinct Limonium plant:

• • 1. Compact, upright and uniformly mounded plant habit.
  • 2. Freely flowering habit.
  • 3. Violet blue to violet-colored flowers arranged in compact inflorescences.
  • 4. Good garden performance.

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 plant size as plants of the new Limonium are taller than plants of the female parent selection. In addition, plants of the new Limonium have larger flowers than plants of the female parent selection.

Plants of the new Limonium can be compared to plants of the male parent selection. Plants of the new Limonium differ primarily from plants of the male parent selection in plant size as plants of the new Limonium are more compact than plants of the male parent selection.

Plants of the new Limonium can be compared to plants of Limonium perezii ‘F.T. Hubbard’, not patented. In side-by-side comparisons conducted in Rijsenhout, The Netherlands, plants of the new Limonium differed primarily from plants of ‘F.T. Hubbard’ in the following characteristics:

• • 1. Plants of the new Limonium were more compact than plants of ‘F.T. Hubbard’.
  • 2. Inflorescences of plants of the new Limonium were more compact than and not as open as inflorescences of plants of ‘F.T. Hubbard’.
  • 3. Plants of the new Limonium had smaller flowers than plants of ‘F.T. Hubbard’.
  • 4. Plants of the new Limonium had a shorter flowering cycle than plants of ‘F.T. Hubbard’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Limonium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Limonium plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Zalimsal’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants of the new Limonium grown during the summer in 19-cm containers in a glass-covered greenhouse in Rijsenhout, The Netherlands and under potted Limonium production conditions. During the production of the plants, day temperatures ranged from 18° C. to 25° C. and night temperatures ranged from 16° C. to 18° C. Plants were 16 weeks old when the photograph and description were taken. Color references are made to The Royal Horticultural Society Colour Chart, 1991 Edition, except where general terms of ordinary dictionary significance are used.
