Abstract:
A new and distinct cultivar of  Phalaenopsis  plant named ‘ P . Ho&#39;s Colourful Bubbles’, particularly characterized by its attractive and unique light green flowers with light pink shaded petals, freely flowering habit, freely branching and thick flowering stems, and strong growth ability.

Description:
Botanical classification:  Phalaenopsis  sp. 
     Variety denomination: ‘ P . Ho&#39;s Colourful Bubbles’. 
     The present invention relates to botanical classification/cultivar designation:  Phalaenopsis  Orchid cultivar  P . Ho&#39;s Colourful Bubbles. 
     BACKGROUND OF THE INVENTION 
     The present invention comprises a new and distinct cultivar of  Phalaenopsis  Orchid, and hereinafter referred to by the cultivar name, ‘ P . Ho&#39;s Colourful Bubbles’. 
     The new cultivar is a product of a planned breeding program conducted by the inventor in Hualien, Taiwan. The objective of the breeding program is to create new uniform pot-type  Phalaenopsis  Orchid cultivars having attractive flower coloration. 
     The new cultivar breeder was Tin-Fan Ho. The new cultivar was discovered by the inventor from within the progeny of a cross-pollination of two identified proprietary selections of  Phalaenopsis  Orchid, not patented, in April, 1998, in a controlled environment in Taiwan. Later, it was verified and registered in Royal Horticulture Society (R.H.S.) and had its variety name “ P . Ho&#39;s Colourful Bubbles” on September 2001. 
     Asexual propagation by tissue culture in a laboratory in Hualien, Taiwan has been used to increase the number of plants for evaluation and has demonstrated that the unique combination of characteristics as herein disclosed for the new  Phalaenopsis  Orchid are firmly fixed and are retained through successive generations of asexual reproduction. 
     SUMMARY OF THE INVENTION 
     The following traits have been repeatedly observed and are determined to be basic characteristics of ‘ P . Ho&#39;s Colourful Bubbles’ which, in combination, distinguish this  Phalaenopsis  Orchid as a new and distinct cultivar:
         1. Light green flowers with light pink shaded petals.   2. ‘ P . Ho&#39;s Colourful Bubbles’ has much more branches and flowers than other green  Phalaenopsis.      3. Strong growth ability and disease resistance.   4. A compound raceme inflorescence and thick flowering stem.       

     Plants of the new cultivar differ primarily from plants of the parent cultivars in the flower color. In particular, the flower color of parent ‘ P . Ho&#39;s Little Caroline’ is white with red stripe and the flower color of parent ‘ P . Dou-dii Golden Princess’ is yellow with red spots, whereas the flower color of ‘ P . Ho&#39;s Colourful Bubbles’ is green. 
     Plants of new  Phalaenopsis  Orchid can be compared to plants of the culture  P . Fortune Saltzman ‘Maple Bridge’ (not patented), differing from plants of the cultivar  P . Fortune Saltzman ‘Maple Bridge’ in the following characteristics:
         1. Plants of the new  Phalaenopsis  Orchid are bigger than plants of the cultivar  P . Fortune Saltzman ‘Maple Bridge’.   2. Plants of the new  Phalaenopsis  Orchid have more branches and flowers than plants of the cultivar  P . Fortune Saltzman ‘Maple Bridge’.   3. Plants of the new  Phalaenopsis  Orchid have more roots than plants of the cultivar  P . Fortune Saltzman ‘Maple Bridge’.   4. Plants of the new  Phalaenopsis  Orchid have stronger disease resistance than plants of the cultivar  P . Fortune Saltzman ‘Maple Bridge’.   5. The natural flowering  Phalaenopsis  Orchid is from February to June, whereas the natural flowering season of  P . Fortune Saltzman ‘Maple Bridge’ is from April to June, in the northern part of Taiwan.   6. Plants of the new  Phalaenopsis  Orchid have compound raceme inflorescences and the  P . Fortune Saltzman ‘Maple Bridge’ has solitary inflorescences.   7. Plants of the new  Phalaenopsis  Orchid have rhombate-shaped petals, and  P . Fortune Saltzman ‘Maple Bridge’ has elliptical-shaped petals.
