Alnwick Garden information
Lonely Planet review
As spectacular a bit of green-thumb artistry as you'll see in England, this is one of the northeast's great success stories. Since the project began in 2000, the 4.8-hectare walled garden has been transformed from a derelict site into a spectacle that easily exceeds the grandeur of the castle's 19th-century gardens, with a series of magnificent green spaces surrounding the breathtaking Grand Cascade – 120 separate jets spurting more than 30,000L of water down 21 weirs for everyone to marvel at and kids to splash around in.
There are half a dozen other gardens, including the Franco-Italian-influenced Ornamental Garden (with more than 15,000 plants), the Rose Garden and the particularly fascinating Poison Garden , home to some of the deadliest – and most illegal – plants in the world, including cannabis, magic mushrooms, belladonna and even tobacco.
