Diarmuid Gavin's own dream gardening goal is to create a wonderful garden at Dublin's Christ Church Cathedral.
He revealed that his own cherished goal was to do something special at the historic Dublin church in the years ahead.
"It's been a dream of mine," he told Jonathan Healy, who was hosting the Pat Kenny Show on Newstalk radio yesterday.
Sometime in the future he wants to create "a great garden" in the church grounds that tourists and visitors could also enjoy, he said.
Gavin will be participating in the Dublin Garden Festival on the weekend beginning Friday, June 19.
The theme of this year's festival is fairy tales and the cathedral will be adorned with floral installations and props aimed at transform it into "a magical wonderland".
The award- winning garden designer will be the main attraction during a champagne breakfast at the cathedral deanery on Werburgh Street on Sunday morning.
Gavin also told Newstalk that he is participating in a project to encourage communities around Ireland to create communal gardens commemorating the 1916 Rising.
He accepted an invitation from Senator Mark Daly to become involved in the Glor na Gael project to assist in the creating of designs for the gardens in each locality.
Each of the gardens is expected to feature the planting of seven trees, one for each of the executed signatories of the Proclamation of the Irish Republic.
Each garden will also have a tricolour and a copy of the proclamation on display.
Gavin said that there was plenty of time for communities and tidy towns competition committees and other groups to plan, design, and create a 1916 garden in their own areas.
The nationwide project aims to have the gardens ready to be formally inaugurated in each city, town, and village on Easter Monday, 2016, to mark the centenary event that had such a profound affect on the history of Ireland.
