Managing director Geoff Caesar said the range is the first of its kind, consisting of 25 herbaceous perennials offering colour, form and interest from late spring to autumn.
"We are going to be the only supplier of this in the marketplace - none of the plants are exclusive to Bransford Webbs but we are putting the whole package together with posters and individual labels for each plant," he added.
"The challenge with it is that the gardener is buying green plants and not ones that are in flower, so it requires a little bit of work and patience. But we think the gardener has that because grow your own has been so successful."
He said the concept was trialled on the market last year and if this year's promotional package is successful the nursery will look at doubling the volume for 2012.
The initiative is being launched in conjunction with the nursery's 50th anniversary and marks the beginning of ambitious expansion plans. Caesar explained: "We have written a five-year plan through to 2015 and that includes looking at crops and talking to customers.
"We have 15,000m of land blocks adjacent to our land and one block will become a dispatch office and the other two will become production space. This year we plan to build the dispatch office and 5,000m of production space."
He said he was in talks with Advantage West Midlands about securing grant funding towards the project, similar to that received by Farplants for its new dispatch centre (HW, 28 January).
