Anigozanthos 'Baby Roo'

ORIGIN: Anigozanthos 'Baby Roo' is the result of a manipulated cross between a tetraploid clone of A. gabrielae (female) and an induced tetraploid form of Anigozanthos 'Bush Ranger' (male). The normal diploid form of Anigozanthos 'Bush Ranger' is sterile, the tetraploid form is fertile. This cross was done by Dr R J Greisbach of the United States Department of Agriculture in Beltsville, Maryland. Registration applied for by Dr R J Greisbach, Maryland, USA., January 1990.

DESCRIPTION: This cultivar is dwarf, growing only to 0.2m tall and 0.15m across with leaves up to 150mm long. The flowers are bicoloured with a bright red ovary and an emerald green perianth. The intensity of colour is temperature dependant, cooler temperatures result in deeper colour. The flowers are tubular and up to 60mm long. This cultivar flowers continually with no dormant period.

Under this international program, this cultivar has received wide publicity. The colchicine-induced tetraploidy procedure has been published in the journal "HortScience" (Greisbach, R J 1990.
