Title: Geranium plant named ‘Fislunova’

Description:
BACKGROUND OF THE INVENTION 
     The present invention comprises a new and distinct cultivar of geranium plant, botanically known as  Pelargonium peltatum , and hereinafter referred to by the cultivar name ‘Fislunova’. 
     ‘Fislunova’ is a product of a planned breeding program which had the objective of creating white flowering cultivars with large flower heads and with a well-branched and only moderately vigorous growth habit. 
     ‘Fislunova’ was originated from a hybridization made by the inventor, Angelika Utecht, in a controlled breeding program in Galder, Gran Canaria, Spain, in 1993. The female parent was the patented variety ‘Fisbliz’ (U.S. Plant Pat. No. 9,373), having single white flowers, medium green leaves with slight zonation, and vigorous growth. The male parent of ‘Fislunova’ was an unnamed hybrid derived from a cross between ‘Fisbliz’ and a self-seedling from ‘Schneekönigin’ (syn. ‘Snow Queen’). The unpatented cultivar ‘Schneekönigin’ is characterized by large, double, white flowers, light to medium green foliage, and moderately vigorous growth. 
     ‘Fislunova’ was selected as one flowering plant within the progeny of the stated cross by the inventor, Angelika Utecht, in the spring of 1994 in a controlled environment in Galdar, Gran Canaria, Spain. 
     The first act of asexual reproduction of ‘Fislunova’ was accomplished when vegetative cuttings were taken from the initial selection in the summer of 1994 in a controlled environment in Galder, Gran Canaria, Spain by Angelika Utecht. Horticultural examination of plants grown from cuttings of the clone initiated in May 1995 in Hillscheid, Federal Republic of Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fislunova’ are firmly fixed and are retained through successive generations of asexual reproduction. 
     BRIEF DESCRIPTION OF THE INVENTION 
     The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fislunova’, which in combination distinguish this geranium as a new and distinct clutivar: 
     1. Large, white, double flowers; 
     2. Compact, semi-spherically shaped inflorescence; 
     3. Medium-green foliage with slight zonation; 
     4. Moderately compact plant habit; and 
     5. Medium spring flowering response. 
     ‘Fislunova’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity and daylength without any change in genotype of the plant. The following observations, measurements, and comparisons describe plants grown in Hillscheid, Germany, and in Langley, British Columbia, Canada, under greenhouse conditions which approximate those generally used in commercial practice. 
     Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fislunova’ are the patented variety ‘Fisuna’ (U.S. Plant Pat. No. 9,522) and the unpatented cultivar ‘Scheekönigin’, ( syn, ‘Snow Queen’). Reference is made to Chart A which compares certain characteristics of ‘Fislunova’ to those same characteristics of ‘Fisuna’.

     In general comparison to ‘Fisuna’, ‘Fislunova’ has larger white florets with less tendency to develop a pink hue; rounder and more uniformly shaped umbels and shorter, but stronger, peduncles; and a more compact plant habit. Furthermore, the leaves of ‘Fislunova’ have less distinct and more rounded lobes. In comparison to ‘Schneekönigin’, ‘Fislunova’ has differeently shaped leaves with less distinctly developed lobes, and a more intense and more stable green foliage color.

     DETAILED BOTANICAL DESCRIPTION 
     The measurements were taken in Langley, British Columbia, Canada, on May 26, 1998—10 weeks after planting of rooted cuttings into 15-cm pots. The plants had not been pinched. In the following description, color references are made to The Royal Horticultural Society Colour Chart (R.H.S.). The color values were determined indoors from flowers developed in a greenhouse in May 1998 in Hillscheid, Germany.
