HTA chief executive Carol Paris was in Ireland last week with Bord Bia marketing specialist Carol Marks to discuss a joint bid for funding in September, to be match-funded by GIMB members, who include retailers, manufacturers and trade bodies.
Two or more countries need to get together to apply for funding, hence the link to Ireland. Retail Excellence Ireland is also involved.
GIMB project manager David Arnold said the campaign is "gathering pace" and companies and bodies including the RHS, Garden Industry Manufacturers Association, Bord na Mona, Westland and Hozelock have committed money.
He added that £350,000 is the minimum amount required to get it going but this could mean £10,000 each from 35 companies.
