Flower power is on display at 21 venues around the Island from July 3-9.
Organisers hope that the festival, which this year has taken a theme to tie-in with Island of Culture, would bloom into an even bigger success than last year.
Committee member Waveney Jenkins said: 'The rebirth of the Isle of Man Flower Festival last year encouraged a large number of churches to apply to join this year - and there will be 21 venues around the Island filling their premises with wonderful floral art.
'The focus on Our Island of Culture will bring an added dimension to the festival - and to celebrate this there will be a photographic competition to find the best photograph to exemplify the theme.'
Waveney added: 'Flower arrangement has moved on from the era of Constance Spry - and though there are still some beautiful traditional arrangements to be found - some of the creations have moved more into the realm of sculpture.
'A recent event was held in Dublin where floral art from all over the world was exhibited by members of the World Association of Flower Arrangers (WAFA) - some amazing works that would hold their own in any art gallery.
'The Manx event is a wonderful festival that provides a reason to drive around the lesser known corners of the Island, see inside some beautiful old buildings - and some unexpected new ones - as well as wonder at what can be done with flowers and foliage to create wonderful artworks.'
A 32-page glossy brochure, produced by Quine and Cubbon, contains a map of the participating venues plus details of opening times at each location. You can also find out details by visiting www.flowerfest.im.
