Abstract
A new cultivar of Spathiphyllum plant named ‘Sweet Silvana’ that is characterized by white to cream colored spathes, dark green leaves and a fast growth rate.
Description
Botanical classification: Spathiphyllum Schott.
Variety denomination: ‘Sweet Silvana’.
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 Silvana’.
‘Sweet Silvana’ is a hybrid that originated from the hybridization of the female or seed parent a proprietary Spathiphyllum Schott. identified as 96251-55 (not patented) and the male or pollen parent a proprietary Spathiphyllum Schott. identified as 96099-50 (not patented). The cultivar ‘Sweet Silvana’ was selected by the inventor in September of 1999 as a single plant within the progeny of the stated cross in Honselersdijk, The Netherlands.
Asexual reproduction by tissue culture of the new cultivar ‘Sweet Silvana’ was first performed in 2000 in Honselersdjik, The Netherlands. Since that time, under careful observations, 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 ‘Sweet Silvana’.
-
- 1. Spathiphyllum ‘Sweet Silvana’ exhibits white to cream colored spathes.
- 2. Spathiphyllum ‘Sweet Silvana’ exhibits dark green leaves.
- 3. Spathiphyllum ‘Sweet Silvana’ exhibits a fast growth rate.
The closest comparison cultivar is Spathiphyllum ‘Sweet Pablo’ (U.S. Plant Pat. No. 10,817). The new cultivar ‘Sweet Silvana’ is distinguishable from ‘Sweet Pablo’ by the following characteristics:
-
- 1. ‘Sweet Silvana’ has flowers that are more cream colored. The flowers of ‘Sweet Pablo’ are white'.
- 2. ‘Sweet Silvana’ has a larger height than ‘Sweet Pablo’.
- 3. ‘Sweet Silvana’ has darker green leaves than those of ‘Sweet Pablo’.
The new cultivar ‘Sweet Silvana’ is distinguishable from the male parent Spathiphyllum ‘96099-50’ in having narrower leaves. The new cultivar ‘Sweet Silvana’ is distinguishable from the female parent Spathiphyllum ‘96251-55’ in having fewer leaves.
The accompanying photograph illustrates the distinguishing traits of Spathiphyllum ‘Sweet Silvana’. The plant in the photograph shows an overall view of a 47 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 ‘Sweet Silvana’. Data was collected in Honselersdijk, The Netherlands from 47 week old greenhouse grown plants in 17 cm containers. The time of year was Spring and the average temperature was 22 degrees Centigrade during the day and 20 degrees Centigrade at night. No photoperiodic treatments was used. 80-100 PPM of Gibberallic acid was applied for flower initiation. 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. ‘Sweet silvana’ 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.
