HTA chief executive Carol Paris said: "At the very heart of the show the New Plant Awards showcase the best in new plant introductions from UK plant suppliers. It is fantastic that we have so many entries this year.
"Garden retailers have seen strong plant sales this year and the HTA National Plant Show will be the best place to view new plants coming onto the market."
The award winners will be announced and presented on the morning of 24 June. Winners will be selected for the quality of plant, suitability for the market and whether it is an improvement on other plants available. All entries and winners will be displayed in the New Plant Area for visitors to see.
All entries will be entered into the Visitor Vote, sponsored by Floramedia, to be announced on 26 June.
Last year New Leaf Plants took the crown of ‘Best in Show’ with Clematis ‘Beautiful Bride’ which also won the Visitor Vote award.
