plant named ‘Sprilomjan’

Abstract

A new and distinct cultivar of Lomandra plant named ‘Sprilomjan’, characterized by its upright plant habit with foliage initially erect to slightly outwardly leaning; vigorous growth habit during propagation and subsequent nursery production; numerous leaves, dense and bushy appearance; long narrowly lanceolate leaves that are yellow green in color; and good garden performance.

Description

Botanical designation: Lomandra confertifolia ssp. pallida.

Cultivar denomination: ‘SPRILOMJAN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lomandra plant, botanically known as Lomandra confertifolia ssp. pallida, and hereinafter referred to by the name ‘Sprilomjan’.

The new Lomandra plant is a product of a planned breeding program conducted by the Inventor in Pakenham, Victoria, Australia. The objective of the breeding program is to create new upright Lomandra plants with strong plant growth in propagation and subsequent nursery production.

The new Lomandra plant originated from an open-pollination in Pakenham, Victoria, Australia in 2014, of an unidentified selection of Lomandra confertifolia ssp. pallida, not patented, as the female, or seed parent with an unknown selection of Lomandra confertifolia ssp. pallida as the male, or pollen, parent. The new Lomandra plant was discovered and selected by the Inventor as a single plant from within the progeny of the stated open-pollination in a controlled environment in Pakenham, Victoria in 2016.

Asexual reproduction of the new Lomandra plant by in vitro micropropagated tip cuttings in Pakenham, Victoria, Australia since 2016 has shown that the unique features of this new Lomandra plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Lomandra have not been observed under all possible combinations of environmental conditions and various cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Sprilomjan’. These characteristics in combination distinguish ‘Sprilomjan’ as a new and distinct Lomandra plant:

• • 1. Upright plant habit with foliage initially erect to slightly outwardly leaning.
  • 2. Vigorous growth habit during propagation and subsequent nursery production.
  • 3. Numerous leaves, dense and bushy appearance.
  • 4. Long narrowly lanceolate leaves that are yellow green in color.
  • 5. Good garden performance.

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

• • 1. Plants of the new Lomandra grow more vigorously during propagation than plants of the female parent selection.
  • 2. Plants of the new Lomandra are denser than plants of the female parent selection.

Plants of the new Lomandra can be compared to plants of the Lomandra hybrida ‘Lomlon’, disclosed in U.S. Plant Pat. No. 23,034. In side-by-side comparisons, plants of the new Lomandra differ primarily from plants of the ‘Lomlon’ in the following characteristics:

• • 1. Plants of the new Lomandra are more vigorous than plants of ‘Lomlon’.
  • 2. Plants of the new Lomandra are denser than plants of ‘Lomlon’.
  • 3. Plants of the new Lomandra have shorter inflorescences and peduncles than plants of ‘Lomlon’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Lomandra plant 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 accurately describe the colors ofthe new Lomandra plant.

The photograph on the first sheet comprises side perspective view of a typical plant of ‘Sprilomjan’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Sprilomjan’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer and autumn in 30-cm containers in an outdoor nursery in Peats Ridge, New South Wales, Australia and under conditions and practices which approximate those generally used in commercial Lomandra plant production. During the production of the plants, day temperatures ranged from 23° C. to 28° C., night temperatures ranged from 10° C. to 18° C. and light levels ranged from 100 to 110 klux. Plants were two years old when the photographs and the botanical description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
