THE garden at Willow Holt in Thorney has been described as “an oasis in agricultural fenland,” and on Sunday the garden will open to visitors, as part of The National Gardens Scheme.

Developed over 20 years by owners Angie and Jonathan Jones, the site has a history of gravel digging followed by rubbish tipping. It’s been transformed, but the past has left more changes in levels than one expects in the fens.

The dells are water-filled, providing a home for great crested newts and dragonfly larvae. Meandering paths, strange sculpted creatures, meadow and woodland create an intriguing natural garden and a background for hundreds of plants.

The garden, to be found in Willow Hall Lane, is open from 11am to 5pm. Entry costs �4.

Since 1927, the National Gardens Scheme has raised more than �35 million for the charities it supports, and is the biggest single donor to both Macmillan Cancer Support and Marie Curie Cancer Care.
