HTA National Plant Show

At the HTA National Plant Show you can meet British plant suppliers in two days at NAEC Stoneleigh, from seed, plug and liner producers to growers of specimen plants and heavy trees. It is a two-day UK environmental horticulture trade show run by the Horticultural Trades Association (HTA), which describes it as the only UK trade show dedicated to plants for British plant suppliers. As a buyer you can meet growers, see varieties launched in the past year and vote in the New Plant Awards Visitor Vote.

Free entry to the 2027 show

You can attend free as a trade visitor when the next edition takes place on Tuesday 29 and Wednesday 30 June 2027, using Halls 1 and 2 at NAEC Stoneleigh. For 2027 the HTA says trade manufacturers and suppliers will be mixed in with the plant suppliers across both halls. At the 2026 show, doors opened from 9:00 to 17:00 on the first day and from 9:00 to 16:00 on the second.

Who you will meet

You will be among the plant buyers and decision makers from across the industry that the show is aimed at. According to figures published by the HTA, 75% of visitors are decision makers or influencers, 75% come to catch up with suppliers they already buy from and 68% come looking for ideas for new stock and products.

The 2026 edition brought together 157 exhibiting companies on 267 stands over two halls. The HTA reports more than 1,200 unique visitors at that event. Compare it with other shows in the agriculture and horticulture calendar, or read our guide to choosing your first UK trade show.

New varieties at the New Plant Awards

The New Plant Awards show you plant varieties brought to market within the previous year. The HTA calls the awards the heart of the show. Almost 100 plants were entered in 2026. A judging panel drawn from growers, retailers, educators and garden media chooses a winner in seven categories and an overall Best in Show. ICL Group was the 2026 New Plant Awards sponsor.

You also get a say through a separate Visitor Vote, sponsored by Floramedia, in which you pick a favourite from the seven category winners by placing a token in the voting boxes near the show entrance. Visitors on day one and those arriving before 11:00 on day two can vote. In 2026 Kernock Park Plants won both Best in Show and the Visitor Vote with Antirrhinum ‘Shiryu Kiss’.
