Tickets are now on sale for the Hidden Gardens of Bury St Edmunds, which is marking its 30th anniversary this year.
Since 1987, tens of thousands of people have visited town centre gardens that are not normally visible from the street, raising more than £300,000 for St Nicholas Hospice Care in the process.
Last year a total of £21,224 was collected, but event organiser Jill Carter is hopeful that figure can be surpassed this time around.
“We want to raise at least the same amount as last year and ideally better it,” she said.
“I am confident that can be done because it is a well established event.
“It is the 30th event as well and that should create a buzz. People like a milestone.
“We have contacted those that have previously been involved but no longer take part.
“Hopefully we can turn it into a bit of a reunion.
This year’s event, which will take place on Sunday, June 19, is set to feature two new gardens in Whiting Street and St John’s Street, while visitors are also being asked to help design a scheme to transform a charity’s courtyard into a therapeutic area for its clients.
The charity in question is Risbygate Street-based Focus 12, who help those with addictions to drugs and alcohol.
“I have not seen either of the new gardens, but I am told they are impressive,” added Jill.
“As for Focus 12, we decided to try something different.
“It is a blank canvas and I think the budget is limited, but gardeners are creative.”
Tickets costing £5 can be purchased in advance from the Apex or from Angel Hill on the day.
