Origin and Breeding Controlled pollination: seed parent
proprietary breeding line designated as “double white
flowered” x pollen parent proprietary breeding line
designated as “purple trailing” in a planned breeding
program in Arroyo Grande, California. The seed parent is
characterised by white flower colour. The pollen parent is
characterised by trailing plant habit and purple flower
colour. ‘Balrufllav’ was selected from the seedling progeny
of this cross in Apr 1998 at Arroyo Grande, California,
USA. Selection criteria: plant habit, flower type, flower
diameter, corolla lobe colour, vigour. Propagation:
vegetative tip cuttings. ‘Balrufllav’ has been found to be
uniform and stable through many generations since
selection. Breeder: Kerry Strope, Ball FloraPlant, Arroyo
Grande, California, USA.
