The spectacular gardens at Arley have been voted amongst the best in Europe. These award winning Grade II* listed grounds cover over 7ha. The present gardens were heavily influenced by Rowland and Mary Egerton-Warberton in the mid-nineteenth century, although there have been some alterations since.
One of the highlights of the gardens is The Ilex Avenue, with 14 very distinctive evergreen holm oaks. Other gardens include the kitchen and herb gardens, as well as a scented garden constructed much more recently in 1977. Beyond the house at Arley is The Grove, planted with much wilder species in a less ordered manner. Typical species here include oak, birch, beech, acer, cornus, pieris, kalmia and many more.
