Title: Kalanchoe plant named ‘Cassandra’

Description:
Latin name of genus and species of plant claimed:  Kalanchoe blossfeldiana.    
   Variety denomination: ‘Cassandra’. 
   BACKGROUND OF THE INVENTION 
   The present invention comprises a new and distinct  Kalanchoe  plant, botanically known as  Kalanchoe blossfeldiana , and hereinafter referred to by the cultivar name ‘Cassandra’. 
   The new cultivar was developed by the inventor through a controlled breeding program during August 1997 in The Netherlands. The female (seed) parent of ‘Cassandra’ was the proprietary  Kalanchoe blossfeldiana  selection designated ‘93226-14’ (not patented), characterized by its red flowers and good branching habit. The male (pollen) parent of ‘Cassandra’ was the proprietary  Kalanchoe blossfeldiana  selection designated ‘95012’ (not patented), characterized by its red-orange flowers and dark green foliage. ‘Cassandra’ was discovered and selected as a flowering plant within the progeny of the stated cross by the inventor in June 1998. 
   Asexual reproduction of the new cultivar at Arroyo Grande, Calif. and West Chicago, Ill., has been through the use of terminal vegetative cuttings and has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and retained through successive generations of such asexual propagation. 
   SUMMARY OF THE INVENTION 
   It was found that the cultivar of the present invention:
         (a) exhibits bright red flowers,   (b) forms dark green foliage,   (c) exhibits a good basal branching character, and   (d) exhibits a compact upright growth habit.       

   The new cultivar of the present invention can be compared to ‘Arjuno’ (U.S. Plant Pat. No. 10,485). In side by side comparisons with ‘Arjuno’, it is found that the new cultivar is more compact, in terms of plant height and the number of branches, and has fewer flowers per plant. A detailed comparison can be found in Table 1. 

   
     BRIEF DESCRIPTION OF PHOTOGRAPH 
     The accompanying photograph shows as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. The plants were grown in a greenhouse at West Chicago, Ill., U.S.A. 
   

   DETAILED BOTANICAL DESCRIPTION 
   The cultivar ‘Cassandra’ has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length. 
   The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined on Jan. 4, 2001 between 9:00 and 9:30 am under natural daylight. The plants used for the following observations and measurements were produced from cuttings taken from stock plants and grown in West Chicago, Ill. In 10 cm pots for sixteen (16) weeks. Plants were grown in a double poly carbonate covered greenhouse under conditions comparable to those used in commercial practice while utilizing a soilless growth medium and maintaining temperatures of approximately 82° F. during the day and approximately 66° F. during the night. Plants were exposed to three weeks of long days followed by 9 weeks of short days. Growth regulators were applied as follows: B nine, 3000 ppm at days 17 and 28 and 1500 ppm day 42.
