Description

DESCRIPTION OF THE DRAWINGS

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

(6) FIG. 5 shows a close-up view of the upmost tip of the main shoot of the new variety; and

(7) FIG. 6 shows a close-up view of a branch of the new variety.

DESCRIPTION OF THE PLANT

(8) The following detailed description sets forth the characteristics of the new cultivar. The data that defines these characteristics were collected by asexual reproductions performed via upright, upper branch shoot cuttings in 2008 carried out in Hörstel-Riesenbeck, Germany. Plants of the new variety were grown under natural daylight and outdoors with full sun. The color readings and measurements were primarily taken on 4-year-old plants grown in 7.5 liter containers. Color references are primarily to The 2007 R.H.S. Colour Chart of The Royal Horticultural Society of London, Fifth Edition.
