The prize was based on the 1,200 flags planted by trade and public visitors to the Banbury site over the course of the summer.
Each visitor is given a flag to plant in their favourite of the company's new varieties.
The Begonias proved very popular this year with five varieties ranking in the top 11.
‘Sherbert Bon Bon' has a compact cascading habit making it suitable for patio baskets, window troughs and vertical planting schemes.
It produces showy two-tone yellow and pink blush flowers with four external guard petals surrounding a tight double centre to form an attractive and durable flower.
Flower colours become more intense with cooler conditions and will bloom from June right through to September.
It is tolerant of all weathers, self-cleaning and best planted in full sun or semi-shade with a feed once or twice a week.
The variety is available in a Ball 66-plug tray, weeks 12-20. A high-impact Ball label is supplied with the plugs.
