plant named ‘Spamozo’

Abstract

A new and distinct cultivar of Spathiphyllum plant named ‘Spamozo’, characterized by its upright, outwardly arching and uniform plant habit; freely clumping growth habit; bushy and dense plants; glossy dark green-colored leaves; large white-colored spathes that are positioned just above the foliar plane on strong and erect scapes; and good inflorescence longevity.

Description

Botanical designation: Spathiphyllum Schott.

Cultivar denomination: ‘SPAMOZO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Spathiphyllum plant, botanically known as Spathiphyllum Schott. and hereinafter referred to by the cultivar name ‘Spamozo’.

The new Spathiphyllum plant is a product of a controlled breeding program conducted by the Inventor in Naaldwijk, The Netherlands. The objective of the breeding program is to create new year-round flowering Spathiphyllum plants that have glossy dark green-colored leaves, large white-colored spathes and good postproduction longevity.

The new Spathiphyllum plant originated from a cross-pollination made by the Inventor in September, 2010 of a proprietary selection of Spathiphyllum Schott. identified as code number 20071360-36, not patented, as the female, or seed, parent with a proprietary selection of Spathiphyllum Schott. identified as code number 20071584-28, not patented, as the male, or pollen, parent. The new Spathiphyllum plant was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Naaldwijk, The Netherlands in May, 2011.

Asexual reproduction of the new Spathiphyllum plant by in vitro meristem culture in a controlled environment in Naaldwijk, The Netherlands since May, 2011 has shown that the unique features of this new Spathiphyllum plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Spathiphyllum have not been observed under all possible combinations of environmental conditions and 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 ‘Spamozo’. These characteristics in combination distinguish ‘Spamozo’ as a new and distinct Spathiphyllum plant:

• • 1. Upright, outwardly arching and uniform plant habit.
  • 2. Freely clumping growth habit; bushy and dense plants.
  • 3. Glossy dark green-colored leaves.
  • 4. Large white-colored spathes that are positioned just above the foliar plane on strong and erect scapes.
  • 5. Good inflorescence longevity.

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

• • 1. Plants of the new Spathiphyllum are more compact than plants of the female parent selection.
  • 2. Leaves of plants of the new Spathiphyllum are more durable than leaves of plants of the female parent selection.

Plants of the new Spathiphyllum differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Spathiphyllum are more compact than plants of the male parent selection.
  • 2. Leaves of plants of the new Spathiphyllum are more durable than leaves of plants of the male parent selection.

Plants of the new Spathiphyllum can also be compared to plants of Spathiphyllum Schott. ‘Sparanke’, disclosed in U.S. Plant Pat. No. 21,294. In side-by-side comparisons, plants of the new Spathiphyllum differ from plants of ‘Sparanke’ in the following characteristics:

• • 1. Plants of the new Spathiphyllum are more compact than plants of ‘Sparanke’.
  • 2. Leaves of plants of the new Spathiphyllum are smoother than and not as rough as leaves of plants of ‘Sparanke’.
  • 3. Plants of the new Spathiphyllum have larger inflorescences than plants of ‘Sparanke’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Spathiphyllum 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 of the new Spathiphyllum plant.

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

The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Spamozo’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late spring in 14-cm containers in a glass-covered greenhouse in Naaldwijk, The Netherlands and under cultural practices typical of commercial Spathiphyllum production. During the production of the plants, day temperatures ranged from 22° C. to 28° C., night temperatures ranged from 20° C. to 22° C. and light levels averaged 5 klux. Plants were six months old when the photographs and the detailed description were taken.
