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 ‘Poulcas070’.

(2) Specifically illustrated in FIG. 1 of the drawings are an open flower viewed from the top, flower petals detached revealing reproductive flower parts, sepals detached revealing the receptacle, and flower buds at various stages of opening.

(3) Specifically illustrated in FIG. 2 of the drawings are a cluster of flowers on the branch, mature leaves, mature bare stem revealing prickles, juvenile leaves, and juvenile stems. Plants shown are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

(4) The following is a description of ‘Poulcas070’, as observed in its growth outdoor in Odense Denmark. Observed plants are 18 months of age, and were grown on their own roots in 30 cm containers.
