The 40-year-old store, now owned by Garden & Leisure, has new roofs, fixtures and fittings, canopies and walkways.
Manager Andrew Gledhill said: "Percy Thrower's garden centre has changed a lot over the past year. We realised that the centre had started to look a bit tired, so we've carried out a massive refurbishment programme and it's really transformed.
"We've always been seen as a traditional plant centre -- and we still are. But now we offer a lot more. We've renovated the pets and aquatic department -- complete with rabbits, rats and guinea pigs. Then there is a huge craft and gift department, fantastic food halls and tea rooms, and amazing Christmas displays."
