Description
BACKGROUND OF THE NEW PLANT

This new rose originated as a seedling resulting from my crossing of undisseminated seedlings at Richmond, Ind., in the Fall of 1973 with the object of combining the pink color of its pollen parent and to retain the keeping quality of its seed parent. The first flowers appeared in the Spring of 1974 and extensive testing of the plant through repeated propations by grafting, under my direction, at Richmond, Ind., and by budding at Livermore, Calif., has demonstrated that the distinctive characteristics of the plant hold true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWING

My new rose plant is illustrated by the accompanying photographic drawing which, in full color, shows face views of a newly opened flower and a three day opened flower, buds in three stages of opening, and specimens of foliage and wood, the color rendition of this drawing being as nearly true as is reasonably possible to obtain by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new rose plant based upon observation of plants grown in greenhouse at Richmond, Ind., in March of 1981, the color designations being according to The R.H.S. Colour Chart (R.H.S.) published by The Royal Horticultural Society of London, England, the Horticultural Colour Chart by Robert S. Wilson (W), and the Nickerson Color Fan (N).

This new rose variety is particularly distinguished in that it exhibits a clear, light pink color throughout all seasons. This variety is considered to be better than its seed parent in that its color is clear and the bud form is more pointed. Also, this new plant is an improvement on its pollen parent in that it shows increased productivity and is more upright in stature.
