Description

DESCRIPTION OF THE DRAWING

(1) The accompanying color illustrations 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 Poulcy038.

(2) Specifically illustrated in FIG. 1 of the drawings are open flowers viewed from above and from the side, a flower bud upon opening, flower petals detached, and sepals detached showing reproductive flower parts.

(3) Specifically illustrated in FIG. 2 of the drawings are juvenile and mature leaves, bare stems exhibiting thorns, and clusters of flower buds on a branch. Plants shown are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

(4) The following is a description of Poulcy038, 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.
