A dazzling display of hundreds of blooms will be on show next week as part of the Out of the Fire Flower Festival.
The colourful array will be exhibited at Lisburn Cathedral, to celebrate 300 years of worship since the building and the town were destroyed by fire in 1707.
The Out of the Fire Flower Festival, which runs from October 25-28, will also raise money for the ongoing renovation of the Cathedral and hall.
Funds will also go towards helping Mongo Primary School in Sudan.
The four-day show, which has been supported by local businesses, will also feature cookery demonstrations, flax spinning and free tours every hour around the new Castle gardens by the Linen Museum.
The event was masterminded by the renowned floral designer the Rev William McMillan, from Dunmurry.
The show is also supported by the Ballymacash Flower Club two of whose members, Joan Lockhart and Pat Leahey, won a silver gilt award at this year's Chelsea Flower Show.
Carrick rugby player Ian McNeill, who runs a flower shop in Whitehead, Co Antrim will also be involved in flower demonstrations.
Mr McMillan said: "I am delighted to be involved in this wonderful event which is raising money for such a great cause, while at the same time bringing visitors a fantastic day out - I'm sure guests to the show will be delighted by the spectacular display of flowers.
"A great deal of work has gone into this project by a lot of people who are dedicated to the refurbishment of this beautiful Cathedral and also to providing a much needed school building for the 265 pupils who attend the Mongo Primary School in Sudan where the classrooms are currently grass huts with no walls.
"A new school will undoubtedly help these students get the education they deserve."
Entry to the festival is free, but donations are welcome.
Those wanting to attend the demonstration on the Saturday afternoon can get tickets costing £10 from the Lisburn Cathedral office, telephone 028 92 602400.
