Title: Pelargonium plant named ‘Surfing Lilac’

Description:
Genus and species:  Pelargonium domesticum.    
   Variety denomination: ‘Surfing Lilac’. 
   BACKGROUND OF THE NEW PLANT 
   The present invention comprises a new and distinct cultivar of geranium, botanically known as  Pelargonium domesticum,  and hereinafter referred to by the cultivar name ‘Surfing Lilac’. It is characterized by having a light purple flower color, upright growth habit and early maturation. The new cultivar originated from an open pollinated population of  Pelargonium  which consisted of one female  Pelargonium  line and approximately 100 male breeding lines in Kanegawa, Japan in 2001. The female parent breeding line is the publicly available  Pelargonium  variety ‘Surfing Purple’ (Japan PBR #11363, available in Japan). The male parent is an unnamed breeding line of unknown origin. 
   F1 seed from the hybridization was harvested from the female parent and sown in the greenhouse in 2001. F1 plants were observed and one plant was selected based on its light purple flower color, growth habit, early maturity, flower size, and multiple inflorescences per plant. The plant was then asexually propagated through cuttings in both Kanagawa, Japan and Salinas, Calif. The plant was further evaluated in the greenhouse from 2001 through 2003 to establish the uniformity and stability of its characteristics. The plant has been shown to reproduce true to type in successive generations of asexual propagation. 

   
     DESCRIPTION OF PHOTOGRAPHS

   DESCRIPTION OF THE NEW CULTIVAR 
   The following detailed descriptions set forth the distinctive characteristics of ‘Surfing Lilac’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. The plant history was taken on 20-week-old plants grown under greenhouse conditions. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.).

             Habit. —Upright and compact.     Height. —35 cm as measured from soil level to top of plant.     Spread. —70 cm.     Life cycle. —Perennial.     Form. —Highly branching.     Time to produce a rooted cutting. —6-8 weeks.     Time to bloom from propagation. —16-20 weeks.     Flowering requirements. —Will flower as long as day length is greater than 12 hours and temperature is above 9° C. for at least 10 hours per day for a minimum of 4 weeks.       
     
       Propagation: The terminal 1.0 to 1.5 inches of an actively growing stem was excised. The vegetative cuttings were propagated in approximately 4-6 weeks. The base of each cutting was dipped for 1 to 2 seconds in a 1:9 solution of Dip&#39;N Grow root inducing solution immediately prior to being placed into cell trays. The cuttings were placed into plastic cell trays having 98 cells and containing a moistened peat moss-based growing medium. The cuttings were misted with water from overhead for 10 seconds every 30 minutes for 3 days. After 3 days, misting was decreased over a period of 2 weeks, upon which time sufficient roots were formed. Rooted cuttings were transplanted and grown in 20 cm diameter plastic pots in a greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium was applied once a day or every other day by overhead irrigation. Pots were top-dressed with a dry, slow-release fertilizer containing 20% nitrogen, 10% phosphorous and 18% potassium. The typical average air temperature was 24° C.

   Comparison with Known Cultivars 
     Pelargonium  ‘Surfing Lilac’ is a unique variety of  Pelargonium  due to its light purple flower color, upright growth habit and early maturity. ‘Surfing Lilac’ is most similar to the  Pelargonium  variety ‘Surfing Purple’ (Japan PBR #11363), which was the female parent, however, there are differences as noted in the table below. A comparison with the male parent is not possible because it is unknown which of the 100 male lines served as the male parent.
