Floral Guernsey first became associated with the Royal Horticultural Society in 2004.
Since then the local organisation has received much support from their larger national counterpart.
In 2010 this link was strengthened as Guernsey appeared for the first time in the society's handbook with a guide of six locations.
Floral Guernsey council member Jane Russell said: "It's brilliant advertising for Guernsey."
The RHS handbook details 140 gardens across the British Isles, Europe and even one in the USA and is circulated to the society's 300,000 members, and has an estimated readership of nearly half a million.
Herm is one of the six sites mentioned in the Handbook
The six sites from Guernsey that are featured range from the tropical gardens of Saumarez Manor to the more traditional garden at Mille Fleur in St Pierre du Bois and the various gardens and floral life of Herm.
Jane said that the island's appearances in the handbook and several editions of the RHS magazine brought much interest from society members looking to visit Guernsey for various events and to see the gardens.
As well as appearing in the handbook Floral Guernsey's association with the RHS has also seen the island host many special talks and demonstrations from visiting and local experts.
In 2010 these talks and demonstrations will include a visit to the island from renowned gardener Fergus Garrett as part of Floral Guernsey's Spring Festival Week, which is due to run from 17 April.
