Description

DESCRIPTION OF THE DRAWINGS

(1) The accompanying photographic drawings illustrate the new variety at 18 weeks of age, with the color being as nearly true as is possible with color illustrations of this type:

(2) FIG. 1 shows an entire plant of the new variety;

(3) FIG. 2 shows an entire plant of the new variety; and

(4) FIG. 3 shows a close-up view of the blooms of the new variety.

DESCRIPTION OF THE PLANT

(5) The following detailed description sets forth the characteristics of the new variety as the result of asexual reproductions performed via in vitro tissue culture cuttings carried out in Gönnebeck, Germany. Plants of the new variety were grown outdoors in 21 cm (4 liter) pots under normal field production conditions, and the color readings and measurements were observed outdoors under natural light on 18 week old plants in Gönnebeck, Germany. Color references are primarily to the 2015 R.H.S. Colour Chart of The Royal Horticultural Society of London, Sixth Edition, except where terms of ordinary significance are used.
