Abstract
A new cultivar of Spathiphyllum plant named ‘Improbra’ that is characterized by white spathes and dark green, glossy leaves.
Description
Botanical classification: Spathiphyllum Schott.
Variety denomination: ‘Improbra’.
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 ‘Improbra’.
‘Improbra’ is a hybrid that originated from the induced hybridization of the female or seed parent a proprietary Spathiphyllum Schott. identified as SP001 (not patented) and the male or pollen parent a proprietary Spathiphyllum Schott. identified as 332 (not patented). The cultivar ‘Improbra’ was selected by the inventor in January 2002 as a single plant within the progeny of the stated cross in Melsen-Merelbeke, Belgium.
Asexual reproduction by tissue culture of the new cultivar ‘Improbra’ was first performed in February of 2002 in Melsen-Merelbeke, Belgium. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.
The following represent the distinguishing characteristics of the new Spathiphyllum cultivar ‘Improbra’.
-
- 1. Spathiphyllum ‘Improbra’ exhibits white spathes.
- 2. Spathiphyllum ‘Improbra’ exhibits dark green, glossy leaves.
The closest comparison cultivar is Spathiphyllum ‘Alpha CD’. The new cultivar ‘Improbra’ is distinguishable from ‘Alpha CD’ by the following characteristics:
-
- 1. ‘Improbra’ has glossier leaves than ‘Alpha CD’.
- 2. ‘Improbra’ has a larger over all size than ‘Alpha CD’.
- 3. ‘Improbra’ has darker green leaves than those of ‘Alpha CD’.
The new cultivar ‘Improbra’ is distinguishable from the male parent Spathiphyllum 332 in having glossier leaves. The new cultivar ‘Improbra’ is distinguishable from the female parent Spathiphyllum SP001 in having darker green leaves.
The accompanying photograph illustrates the distinguishing traits of Spathiphyllum ‘Improbra’. The plant in the photograph shows an overall view of a 35 week old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
The following is a detailed description of the new Spathiphyllum cultivar named ‘Improbra’. Data was collected in Melsen-Merelbeke, Belgium from 35 week old greenhouse grown plants in 24 cm containers. The time of year was Fall and the average temperature was 21 degrees Centigrade during the day and 18 degrees Centigrade at night. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2001 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Improbra’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
