Title: Petunia plant named ‘Sunsurfbv’

Description:
Botanical designation:  Petunia×hybrida.    
   Cultivar denomination: ‘Sunsurfbv’. 
   BACKGROUND OF THE INVENTION 
   The present Invention relates to a new and distinct cultivar of  Petunia  plant, botanically known as  Petunia×hybrida,  and hereinafter referred to by the cultivar name Sunsurfbv. 
   The new  Petunia  is a product of a planned breeding program conducted by the Inventors in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new outwardly spreading  Petunias  with large and attractive flowers. 
   The new  Petunia  originated from a cross-pollination made by the Inventors in August, 2001, of the  Petunia cornuta  Celebrity Burgundy, not patented, as the female, or seed, parent with a proprietary selection of  Petunia cornuta  identified as code number P55h, not patented, as the male, or pollen, parent. The new  Petunia  was selected as a single plant from the resulting progeny of the cross-pollination by the Inventors in a controlled environment in Higashiomi, Shiga, Japan. 
   Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since September, 2003 has shown that the unique features of this new  Petunia  are stable and reproduced true to type in successive generations. 
   SUMMARY OF THE INVENTION 
   Plants of the cultivar Sunsurfbv have not 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 ‘Sunsurfbv’. These characteristics in combination distinguish ‘Sunsurfbv’ as a new and distinct  Petunia  cultivar:
         1. Compact, outwardly spreading, mounded and decumbent plant habit.   2. Vigorous and freely branching growth habit.   3. Freely flowering habit.   4. Lavender-colored flowers with purple-colored venation.   5. Long flowering period.   6. Good garden performance.       

   Plants of the new  Petunia  differ from plants of the female parent, the cultivar Celebrity Burgundy, in the following characteristics:
         1. Plants of the new  Petunia  are more decumbent than plants of the cultivar Celebrity Burgundy.   2. Plants of the new  Petunia  are shorter than plants of the cultivar Celebrity Burgundy.   3. Plants of the new  Petunia  and the cultivar Celebrity Burgundy differ in flower color as plants of the cultivar Celebrity Burgundy have red purple-colored flowers.       

   Plants of the new  Petunia  differ from plants of the male parent selection in the following characteristics:
         1. Plants of the new  Petunia  are more outwardly spreading than plants of the male parent selection.   2. Plants of the new  Petunia  have larger flowers than plants of the male parent selection.   3. Plants of the new  Petunia  and the male parent selection differ in flower color as plants of the male parent selection have white-colored flowers.       

   Plants of the new  Petunia  can be compared to plants of the cultivar Revolution Pinkvein, disclosed in U.S. Plant Pat. No. 9,341. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new  Petunia  differed from plants of the cultivar Revolution Pinkvein in the following characteristics:
         1. Plants of the new  Petunia  were smaller than plants of the cultivar Revolution Pinkvein.   2. Plants of the new  Petunia  had larger flowers than plants of the cultivar Revolution Pinkvein.   3. Plants of the new  Petunia  and the cultivar Revolution Pinkvein differed in petal coloration as plants of the cultivar Revolution Pinkvein had pink-colored petals.

   DETAILED BOTANICAL DESCRIPTION 
   The aforementioned photographs and following observations and measurements describe plants grown in Higashiomi, Shiga, Japan, in 15-cm containers for about four months in an outdoor nursery during the early summer with day temperatures about 23° C. and night temperatures about 13° C. Plants were pinched one time. Color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
