"Our society is very proud of the rose gardens that have been a major part of Frimley Park and Hastings for 50 years. Seeing the joy of visitors' faces is a real pleasure and we are already looking forward to next year's celebration."
The 19ha for the park was donated in the 1950s by Elsie, Arnold and Heathcote Williams, the three children of James and Mary Margaret Williams, in memory of their parents.
The family owned a 1214ha station they named "Frimley" after a village in Surrey, England.
As part of the development of the park, the Hastings Rose Society took charge of developing a comprehensive rose garden from 1965.
Half the proposed number of rose bushes, 20 of each cultivar, were planted in the first year, with the same number planted over the following two years.
Those 4000 bushes across 300 varieties have now grown to more than 5500.
