Title: White rose seedling

Description:
BACKGROUND OF THE NEW PLANT 
     My new variety of rose plant was originated at Richmond, Indiana, as a seedling resulting from my crossing &#34;White Butterfly&#34; (P.P. 1337) with &#34;Promise Me&#34; (P.P. 3167), in the Spring of 1969, with the object of combining the better characteristics of the parents, namely to produce an improved bloom with greater stem length and better growth habit. This new seedling, which first flowered in 1970, reflects the success of this cross and my asexual propagation of this seedling through several generations by grafting at Richmond, Indiana, and by budding at Livermore, California, has demonstrated that the improved characteristics of the new plant hold true from generation to generation and appear to be firmly fixed. 
    
    
     DESCRIPTION OF THE DRAWING 
     This new variety of rose plant is illustrated by the accompanying photographic drawing which shows, in full color, a face view of a fully opened flower, specimens of buds in several stages of opening, specimens of young and mature wood, and typical leaves. The colors shown are believed to be as nearly true as it is reasonably possible to be obtained through conventional photographic procedures. 
    
    
     DESCRIPTION OF THE NEW PLANT 
     The following is a detailed description of my new variety of rose plant based upon observations, made in December 1977, of greenhouse plants grown at Richmond, Ind., the color designations being according to the Robert G. Wilson Horticultural Colour Chart (W) and the R.H.S. Colour Chart (RHS), both issued by The Royal Horticultural Society of London, England.

     This new variety of rose plant is very superior to its seed parent, White Butterfly, in petal texture, length of stem and freedom of growth. This new cultivar is also an improvement over its pollen parent, Promise Me, in its very rapid crop turnover and the longer pointed form of its bud. 
     A particular advantage possessed by this cultivar is its very free growth habit on erect stems of good strength and the high centered and very fine opening form of its blooms.
