| Abstract: |
The new cultivar is a early, rich flowering mass-production variety. It is not sensitive to chlorosis and has high productivity on the motherplant. Its elegant pure white flowers have big umbels and continuously flower. Its good garden performance is shown by its very good resistance to rainfall and bad weather. It does not change from the white color to light pink under unfavorable climatic conditions and does not display a neck break. It also has a vigorous compact mound growth. The new cultivar is an improvement in comparison to the old white variety "PAC Aphrodite". |

1. A new and distinct variety of geranium plant substantially as shown and described. |
| Description: |
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Pelargonium.times.hortorum known by the varietal name `North Star`. The new variety was discovered at Elsner pac Jungpflanzen in Dresden, Germany in April, 1990. The new variety wasdiscovered by crossbreeding several breeding lines, which are unnamed, but which are maintained proprietary for breeding purposes. The new variety was first asexually reproduced by cuttings at Elsner pac Jungpflanzen in Dresden, Germany in September,1990. It has also been trial and field tested from the year after discovery up to now at Elsner pac Jungpflanzen in Dresden, Germany and has been found to retain its distinctive characteristics through successive propagations.
The plant history was taken on six week plants blossomed under the natural light in a green house in 12 cm pots. The cultivar when grown in a glass greenhouse was potted on the Feb. 17, 1995 and flowered on Mar. 30, 1995.
DESCRIPTIONOF THE DRAWING
The accompanying photographic drawing illustrates the new cultivar the color being as nearly true as possible with color illustrations of this type.
DESCRIPTION OF THE NEW PLANT
The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions carried out by Elsner pac Jungpflanzen in Dresden, Germany. The planthistory was taken on six week plants blossomed under natural light in a greenhouse and the color readings were taken indoors under natural light in a room near a window without direct sunlight. Color references are primarily to The R.H.S. Color Chartof The royal Horticultural Society of London.
