Abstract

A distinct cultivar of Spathiphyllum plant named Sweet Pablo, characterized by its glossy green leaves that are held horizontal to the petiole; freely branching habit which gives a dense and full appearance to the plants; vigorous and rapid growth rate; early flowering; numerous large white flowers that are positioned just above the foliage on strong and erect peduncles; and long-lasting flowers.

Description

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 Sweet Pablo.
The new cultivar is a product of a planned and controlled breeding program conducted by the inventor in Monster, The Netherlands. The objective of the breeding program is to create new Spathiphyllum cultivars with good plant form, good leaf and flower proportion, rapid growth rate, and early and continuous flowering.
The new cultivar originated from a cross by the inventor between the proprietary Spathiphyllum Schott selection 91317-3 as the female or seed parent and the proprietary Spathiphyllum Schott selection 92116-11 as the male or pollen parent. The cultivar Sweet Pablo was discovered and selected by the inventor in 1994 as a plant within the progeny of the stated cross in a controlled environment in Monster, The Netherlands. Compared to plants of the female parent, plants of the new Spathiphyllum have lighter green leaves. Compared to plants of the male parent, plants of the new Spathiphyllum are more compact. Additionally plants of the male parent have green spathes whereas plants of the new Spathiphyllum have white spathes.
Asexual propagation of the new cultivar by division and by tissue culture at Naaldwijk, The Netherlands, has shown that the unique features of this new Spathiphyllum plant are stable and reproduced true to type in successive generations of asexual propagation.
The new Spathiphyllum has 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 Sweet Pablo. These characteristics in combination distinguish Sweet Pablo as a new and distinct cultivar:
1. Glossy green leaves that are held horizontal to the petiole.
2. Freely branching habit which gives a dense and full appearance to the plants.
3. Vigorous and rapid growth rate.
4. Early flowering.
5. Numerous large white flowers that are positioned just above the foliage on strong and erect peduncles.
6. Long-lasting 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. The photograph on the first sheet comprises a top perspective view of a typical potted plant of Sweet Pablo.
The photograph on the second sheet comprises a close-up view of the foliage of Sweet Pablo.
The photograph on the third sheet comprises a close-up view of a typical spathe and spadix of Sweet Pablo.
The photograph on the fourth sheet comprises a close-up view of the back of a typical spathe of Sweet Pablo.
