Abstract:
A new and distinct plant producing trumpet-shaped flowers of a good quality and attractive coloration on a twining, vine-like plant.

Description:
BOTANICAL CLASSIFICATION 
       Campsis×tagliabuana  ( C. grandiflora×C. radicans ). 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct variety of Campsis plant which is a cross of an unnamed  Campsis grandiflora  as seed parent and an unnamed  Campsis radicans  as pollen parent. The varietal denomination of the new variety is ‘Kudian’. 
     The first act of asexual reproduction of ‘Kudian’ was in Uithoorn, The Netherlands, by grafting onto  Campsis radicans.  Asexual reproduction by graftings through successive generations in Uithoorn, The Netherlands, has demonstrated that the combination of characteristics as herein disclosed for ‘Kudian’ are firmly fixed and retained through successive generations. 
     Seeds from a cross of  Campsis grandiflora×Campsis radicans  were harvested in 1984 and were planted in the soil in autumn 1984. 
     In January 1987 the seedlings (in total 10 plants) were grafted on  Campsis radicans  as the rootstock. Grafting is desired to get fast flowering. In summer 1987 all the plants flowered. One of them (identified as ‘KU 52’, now known as ‘Kudian’) was different than the other seedlings in the following characteristics: 
     1. Very early flowers 
     2. Many flowers on one plant 
     3. Dark green leaves 
     4. Different orange color of the flowers 
     From 1988 until 1994 ‘Kudian’ was propagated through grafting. The variety was found to be 100% stable. During this period it also appeared that all plants flowered more profusely as compared with the existing variety  Campsis×taglibuana  ‘Mdm Galen’. If, for instance, 100 plants of  Campsis×taglibuana  ‘Mdm Galen’ are planted, only about 70% will flower. If 100 plants of ‘Kudian’ are planted, they all will flower. 
     Further growing of plants of ‘Kudian’ demonstrated the homogeneity and flowering characteristics thereof. 
     SUMMARY OF THE INVENTION 
     The new variety flowers heavily as a young plant and produces large flowers of attractive color. 
     COMPARISION WITH PARENTS 
     The new variety produces larger flowers than either parent and exhibits different flower color. It further differs from its parents in flowering very early, producing dark green foliage and having a different orange flower color. 
    
    
     DESCRIPTION OF ILLUSTRATION 
     The new variety is illustrated in the accompanying illustration, which shows typical flower and growth characteristics, with colors being as nearly true as is possible for illustrations of this type. 
    
    
     DETAILED DESCRIPTION OF THE NEW VARIETY 
     The following is a detailed description of a three year-old plant of the new cultivar as observed in a greenhouse in The Netherlands. Color designations indicated are in accordance with The Royal Horticultural Society Colour Chart (2001) by color plate designations. 
     ‘Kudian’ has not been observed under all possible environmental conditions. Phenotypic expression may vary with variations in environment such as temperature, light intensity, day length and growing and cultural conditions. 
     DESCRIPTION 
     ‘Kudian’ exhibits a climbing habit of about 4 m to 4.6 m high. Leaves are pinnate, dull to shiny dark green. Flowers are often arranged in large, pendulous racemes, trumpet-shaped, having a corolla 5-6 cm across. The color of the outside of the flower is yellowish-orange, while the interior of the flower is orange-red. Flowering occurs in July to September in Uithoorn, The Netherlands. 
     ‘Kudian’ is a very attractive, abundantly flowering plant. When grown in a pot in a greenhouse,the flowers are more of an orange color, with orange red throats and red stripes running lengthways. Also, as a flowering plant, ‘Kudian’ does not grow as tall as other cultivars, making it an attractive pot plant for the consumer. Grown against a wall, this trumpet-flower climber will start flowering quite well within a few years. It is propagated by grafting and is sufficiently hardy to survive a normal winter.
