will be commercially propagated by vegetative cuttings
from stock plants. Breeder: Marga Dummen, Rheinberg,
Germany.
Choice of Comparators ‘Paradise Bonaire’ and ‘Butterfly
Noctua’ were considered as the most similar variety of
common knowledge. The Red Fox Riviera series varieties
are similar to the Paradise series varieties in flower size,
number, colour and earliness. All other varieties available in
Australia were excluded because of their lack of similarity
to either of the above series varieties.
Comparative Trial Comparator: ‘Paradise Bonaire’,
‘Butterfly Noctua’. Location: trials conducted at F& I
Baguley Flower and Plant Growers, Clayton South, VIC
Aug – Dec 1999. Conditions: plants raised on their own
roots from cuttings planted into 150mm pots in commercial
pine bark potting mix on raised glasshouse benches. Pots
were watered and fed using a drip system (one dripper/pot).
The glasshouse walls and roof were sprayed with
whitewash at the start of the trial. All plants were subjected
to the same spray chemical treatments to maintain health.
Trial design: 12 plants of each variety were arranged in
rows. Measurements: from all trial plants.

Origin and Breeding Controlled pollination: seed parent
D8 x pollen parent D0/39 in a planned breeding program.
