Origin and Breeding Spontaneous mutation: of common
non-variegated form of Coleonema pulchrum (also known
as ‘Golden Diosma’, ‘Golden Sunset’ or ‘Sunset Gold’) at
Dromana, VIC. The parental plant is characterised by
golden foliage colour and upright growth habit. A
variegated mutation was observed in 1993, which was
selected through 3 generations to develop ‘Mellow Yellow’.
Selection criteria: variegated pale lemon foliage colour and
semi-prostrate growth habit. Propagation: by cuttings
through several generations to ensure the uniformity and
stability of the selection. ‘Mellow Yellow’ is commercially
propagated by cuttings. Breeder: Stephen Membrey,
Frankston, VIC.
Choice of Comparators common non-variegated form of
Coleonema pulchrum was chosen because it is the parent
plant. No other similar varieties of common knowledge
have been identified.
Comparative Trial Comparator: Coleonema pulchrum.
Location: Dromana, (Lat. 38°S) VIC. Conditions: ambient
outdoor, plants raised as cuttings and transplanted (May
1999) to 150mm pots in a standard soilless media fertilised
with controlled release fertiliser. Trial design: paired
replicates of 10 plants per variety. Measurements: ten to
twenty specimens selected from ten plants; time of
measurement Feb 2000. Observations were also made on
mature plants at Dromana and Devon Meadows where
characteristics appeared to vary from the trial plants.
Prior Applications and Sales
No prior applications. First sold in Australia in Nov 1999.
