Description

DESCRIPTION OF THE DRAWING

(1) The accompanying color illustration show as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems, of Poulcas060. Specifically illustrated in the drawing are open flower above and side view, a cluster of flowers on a branch, petals and sepals detached revealing reproductive flower parts, bare stem showing prickles, and leaves. Plants shown are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

(2) The following is a description of Poulcas060, as observed in its growth in a field nursery in Linn County, Oreg. Observed plants are 2 years of age, and were grown on their own roots. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

(3) For a comparison, several physical characteristics of the rose variety Poulcas031, U.S. Plant Pat. No. 22,502 are compared to Poulcas060 in Chart 1.
