The larest French nursery trade show Salon de Vegetal moves from Angers in February to Nantes on 20-22 June 2017.
The National Plant Show is held at Stoneleigh on 21-22 June 2016 and is set for similar dates next year.
Martin Simmons, HTA head of operations, said: "After seven years The HTA National Plant Show is now firmly established in the horticultural industry calendar as the premier plant event in the UK. This year’s show is already sold out and we have received a record number of entries to the New Plant Awards making it the first choice for UK growers and retailers alike.
"The show has always been held during the third week of June when plants are at their peak and as it’s just post-season it’s a great time for growers and retailers to discuss plans for next year. We are aware that Salon du Vegetal has announced that it is planning to change its 2017 dates to the same dates as NPS and we have informed the organisers of this however we don’t expect it to have any significant impact on either our exhibitors or visitors to NPS."
