The design for the hospice was a joint effort between the charity, which creates gardens at hospices, and the Garden Centre Group (GCG) after a fundraising push secured more than £32,000.
Greenfingers worked with designer Clare Matthews on private and social spaces for teenagers and young adults.
Raised beds encourage patients in wheelchairs to garden, while other features include sensory plants, explained hospice chief executive Tom Hill. He added that Greenfingers also helped with the makeover of children's hospice Helen's House three year's ago.
Founder of both hospices Sister Frances Dominica and GCG marketing director Lorrie Robertson cut the ceremonial ribbon.
