Abstract

A new variety of shrub rose plant having a profuse and continuous production of medium-sized flowers of bright red coloration, the plant being free branching, bushy, and erect in its growth habit and exhibiting an ability to survive Midwestern winter temperatures without weather protection. The plant also shows good field tolerance to foliar diseases such as Blackspot and Powdery Mildew.

Description

BACKGROUND OF THE NEW PLANT
This new rose plant originated as a seedling resulting from a cross of the seed parent Carefree Beauty (Bucbi) (U.S. Plant Pat. No. 4,225) with an unnamed pollen parent obtained by crossing Marlena (U.S. Plant Pat. No. 2,700) with Pippa's Song (unpatented). The new variety was discovered by me at Iowa State University Horticulture Greenhouses, Ames, Iowa, in 1977 and resulted from breeding efforts commenced by me in 1949 at that University. The new plant was selected for propagation because of its continuous and profuse production of bright red flowers and especially because of its ability to survive winter temperatures in Iowa without weather protection and its notable resistance to foliar diseases. Since its discovery, this plant has been asexually reproduced by me, by budding, at Ames, Iowa, and propagated through successive generations to test its retention of the characteristics first observed. Continued propagation of this cultivar has demonstrated that its novel characteristics 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, in full color, shows face and side views of fully-opened flowers and several other stages of the bloom from a tight bud, to a bud with sepals just cracked, to a newly-opened flower. The colors shown are as nearly true as can be reasonably expected to be reproduced by conventional photographic procedures.
DESCRIPTION OF THE NEW PLANT
The following is a description, in detail, of this new variety of rose plant with color designations according to The R.H.S. Colour Chart (R.H.S.C.C.) published by The Royal Horticultural Society of London, England, in collaboration of The British Colour Council (B.C.C.), with reference in some cases to the descriptive color designations adopted by the latter.

The plant is, however, exceptional in its ability to survive under adverse winter conditions and its field tolerance to foliar diseases such as Blackspot and Powdery Mildew.
