In 2001, the two Osteospermum lines were crossed and 37 ovules were removed from ?owers on the female parent and

cultured by standard ovule culture techniques. A total of 10 plantlets were developed. The 10 F1 hybrid plantlets were transplanted to soilless media for greenhouse culture and acclimatiZation. In 2002, the breeder evaluated the plants in pots and the plants were creamy pink in ?ower color and demonstrated vigorous plant growth and earliness to ?ower.
