USPP17782P2 - Limonium plant named ‘Esm Ara’ - Google Patents

Abstract

A new and distinct cultivar of Limonium plant named ‘Esm Ara’, characterized by its upright and somewhat outwardly spreading plant habit; long and strong flowering stems; vigorous and freely branching growth habit; freely and uniformly flowering habit; dense panicles with purple-colored flowers; and good postproduction longevity.

Description

Botanical designation: Limonium sinuatum cultivar Esm Ara.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Limonium plant, botanically known as Limonium sinuatum, and hereinafter referred to by the cultivar name Esm Ara.

The new Limonium is a product of a planned breeding program conducted by the Inventor in El Quinche, Pichincha, Ecuador. The objective of the breeding program was to create new freely branching Limonium cultivars with compact inflorescences and purple-colored flowers.

The new Limonium originated from a cross-pollination made by the Inventor in August, 2001 in El Quinche, Pichincha, Ecuador of a proprietary selection of Limonium sinuatum identified as Code 136, not patented, as the female, or seed, parent and an unidentified selection of Limonium sinuatum, not patented, as the male, or pollen, parent. The new Limonium was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in El Quinche, Pichincha, Ecuador.

Asexual reproduction of the new cultivar by terminal cuttings in El Quinche, Pichincha, Ecuador since February, 2002, has shown that the unique features of this new Limonium are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Esm Ara have not been observed under all possible environmental conditions. 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 ‘Esm Ara’. These characteristics in combination distinguish ‘Esm Ara’ as a new and distinct cultivar:

• • 1. Upright and somewhat outwardly spreading plant habit.
  • 2. Long and strong flowering stems.
  • 3. Vigorous and freely branching growth habit.
  • 4. Freely and uniformly flowering habit.
  • 5. Dense panicles with purple-colored flowers.
  • 6. Good postproduction longevity.

Plants of the new Limonium differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Limonium have more durable leaves than plants of the female parent selection.
  • 2. Plants of the new Limonium flower have denser inflorescences than plants of the female parent selection.
  • 3. Plants of the new Limonium and the female parent selection differ in flower coloration as plants of the female parent selection have blue and white bi-colored flowers.

Plants of the new Limonium can be compared to the Limonium cultivar Crystal Dark Blue, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Limonium differed from plants of the cultivar Crystal Dark Blue in the following characteristics:

• • 1. Plants of the new Limonium were narrower than plants of the cultivar Crystal Dark Blue.
  • 2. Plants of the new Limonium had shorter internodes than plants of the cultivar Crystal Dark Blue.
  • 3. Plants of the new Limonium had larger and more durable leaves than plants of the cultivar Crystal Dark Blue.
  • 4. Plants of the new Limonium had many flowers per inflorescence than plants of the cultivar Crystal Dark Blue.
  • 5. Plants of the new Limonium and the cultivar Crystal Dark Blue differed in flower color as plants of the cultivar Crystal Dark Blue have violet-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Limonium.

The photographs at the top of the sheet comprises a side perspective view of typical flowering stems of ‘Esm Ara’.

The photograph at the bottom of the sheet is a close-up view of a typical inflorescence of ‘Esm Ara’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown in El Quinche, Pichincha, Ecuador, in a polyethylene-covered greenhouse and under commercial production practices. Plants were about eight months old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 12° C. to 30° C., night temperatures ranged from 5° C. to 11° C. and light levels ranged from 1,000 foot candles to 1,150 foot candles. Plants were pinched about nine weeks after planting.
