Swindon's TWIGS Community Garden will open to the public to raise money for good causes on Sunday, 23 May.
The community garden is part of the National Garden Scheme, which gives visitors unique access to over 3,500 exceptional private gardens in England and Wales, and raises money for nursing and health charities.
Thanks to the generosity of garden owners, volunteers and visitors, NGS has donated more than £60m over the years, and core beneficiaries include Macmillan Cancer Support, Marie Curie, Hospice UK and The Queen’s Nursing Institute.
TWIGS, based at Manor Garden Centre in Cheney Manor Road, aims to give people who experience mental health problems the chance to regain confidence and self esteem and to learn new skills.
On May 23, admission will cost £3.50 with no charge for children, and there will be home-made teas and also hot and cold lunches available at the garden centre's Olive Tree café - although these must be booked on 01793 533152.
An NGS spokesperson said: "Our gardens in Wiltshire are ready to welcome everyone.
"Please be advised that it is sensible to check through www.ngs.org.uk before leaving home. Some garden details have changed and some now require booking beforehand, but rest assured you will receive a warm welcome."
The TWIGS Community Garden has been featured in the Garden Answers and Wiltshire Life magazines and on the Great British Gardens website, and has been named among the region's top attractions.
It covers two acres, and features include seven individual display gardens, an ornamental pond, a plant nursery, an Iron Age round house and artworks.
Other gardens named by NGS as opening over the coming weeks include those of Tristenagh House in Potterne, Foxley Manor in Malmesbury and Broadlees House Gardens in Devizes.
