Albion Plants, F J Jackson & Son and Ball Colegrave took the awards at the South West Growers Show last week.
Winner of the best new non-plant product or service was the Powerliner from F J Jackson & Son – a new product from for growing two and three litre hardy shrubs, perennials and fuchsias.
David Jackson, owner of the company said: "We are delighted with our award which looks set to confirm the Powerliner as an industry leader in plant optimisation and growth performance. It provides the benefits of a more expensive P9 liner, but in a cost effective and easy to manage x28 tray unit."
Root systems are developed within the cell tray, creating a healthy and vigorous rootball.
"Quick growing perennials can now be potted, grown to flower and despatched within as little as eight weeks, making it a valuable solution to growers where space is a premium," said Jackson
Steve Rudhall, technical sales representative at Ball Colegrave, who was awarded the prize for its new Helleborus ‘Winterbells’ in the best new plant introduction category said: "Our new breeding of Winterbells is unique as it flowers naturally, reliably and consistently from autumn onwards and offers a good seven months of flowering pleasure."
"It brings new sales windows, faster flowering and minimum fuss culture. It can also manage hard winters exceptionally well and is less prone to root problems in the summer. We are really pleased it has been recognised as a ‘best in class’ and hope the award will play a part in its success."
Brenda Huggons, owner from North Devon-based Albion Plants who was selected as winner for the best nursery stand and overall winner at the show, said: "After a challenging year it is grand to see the fruits of our labour culminating in the display. The award was the icing on the cake of what was a very successful and well attended show, we are delighted to be the winner."
