Title: Echinacea plant named ‘Hot Papaya’

Description:
Botanical designation:  Echinacea hybrida.    
   Cultivar denomination: ‘HOT PAPAYA’. 
   BACKGROUND OF THE INVENTION 
   The present invention relates to a new and distinct cultivar of  Echinacea  plant, botanically known as  Echinacea hybrida , and hereinafter referred to by the name ‘Hot Papaya’. 
   The new  Echinacea  plant originated from an open-pollination in 2005 in Vleuten, The Netherlands of a proprietary selection of  Echinacea hybrida  identified as code number Ec 512-17, not patented, as the female, or seed, parent with an unknown selection of  Echinacea hybrida  as the male, or pollen, parent. The new  Echinacea  was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination grown in an outdoor nursery environment in Zuidwolde, The Netherlands in July, 2007. 
   Asexual reproduction of the new  Echinacea  plant by micropropagation a controlled greenhouse environment in Enkhuizen, The Netherlands since November, 2007, has shown that the unique features of this new  Echinacea  plant are stable and reproduced true to type in successive generations. 
   SUMMARY OF THE INVENTION 
   Plants of the new  Echinacea  have been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. 
   The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hot Papaya’. These characteristics in combination distinguish ‘Hot Papaya’ as a new and distinct cultivar of  Echinacea:  
         1. Upright plant habit.   2. Moderately vigorous growth habit.   3. Strong and thick flowering stems.   4. Freely basal branching habit.   5. Large anemone-type inflorescences with orange red-colored ray and disc florets.       

   Plants of the new  Echinacea  plant can be compared to plants of the female parent selection. Plants of the new  Echinacea  plant differ from plants of the female parent selection in the following characteristics:
         1. Plants of the new  Echinacea  are more freely branching than plants of the female parent selection.   2. Plants of the new  Echinacea  have broader leaves than plants of the female parent selection.   3. Plants of the new  Echinacea  have larger inflorescences than plants of the female parent selection.       

   Plants of the new  Echinacea  can be compared to plants of  Echinacea hybrida  ‘Razzmatazz’ , disclosed in U.S. Plant Pat. No. 13,894. In side-by-side comparisons, plants of the new  Echinacea  differed from plants of ‘Razzmatazz’ in the following characteristics:
         1. Plants of the new  Echinacea  were more freely branching than plants of ‘Razzmatazz’.   2. Plants of the new  Echinacea  had longer leaves than plants of ‘Razzmatazz’.   3. Plants of the new  Echinacea  flowered earlier than plants of ‘Razzmatazz’.   4. Plants of the new  Echinacea  and ‘Razzmatazz’ differed in floret coloration as plants of ‘Razzmatazz’ had dark pink-colored ray florets and red purple-colored disc florets.

   DETAILED BOTANICAL DESCRIPTION 
   The aforementioned photographs and following observations and measurements describe plants grown in Zuidwolde, The Netherlands during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial  Echinacea  production. During the production of the plants, day temperatures ranged from 12° C. to 30° C. and night temperatures ranged from 3° C. to 14° C. Measurements and numerical values represent averages for typical flowering plants. Plants had been growing for six months when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
