The Horsham-based nursery, which specialises in topiary, unusual trees and evergreens, will be giving trade customers five per cent cashback on their purchases over the full year, payable each January.
Owner Angus White said: "We have been selling to the trade for more than 20 years and wanted to give something back to our customers. As far as I am aware, we are the first nursery to offer this kind of reward."
He added: "Anyone wanting cashback will be given a target spend, based on previous years. The only stipulation in receiving the extra five per cent is that this target is met and the cashback will be based on the whole annual spend, not just the amount spent over the target.
"Anyone not reaching their targets will still get the normal discount we offer all trade customers, so cashback is an extra reward."
Architectural Plants will work out customers' cashback figure and prepare a self-billing invoice, including the VAT element.
