Visitors to the open days, which took place over three weeks this July and August, were asked to identify their favourite plants by marking them with blue flags.
‘Bright Red’ is a new addition to the Cabaret range, along with ‘Deep Yellow’, which came second in the visitor vote.
Geranium ‘Angel Eyes Bicolour’, which came third, topped the results for consumer votes.
Ball Colegrave marketing manager Stuart Lowen said: "The results cover a three week window. The first was a wet spell, the second week was dry and the third was a mixture so people saw the plants in a range of conditions."
Ball Colegrave won the runner-up prize in the bedding plants category at the Four Oaks awards last week for its Digitalis Dalmatian series and was given a special mention by the judges for Wallflower ‘Sugar Rush’.
