Overlooking the Clyde, this sheltered woodland garden with Himalayan glen is home to many rare, tender and spectacular rhododendrons and magnolias, along with other beautiful acid-loving plants, such as acers, crinodendrons and embothriums. There’s also a vegetable garden and a large rock garden built around an old quarry.


Important update

With the gradual easing of lockdown restrictions, gardens in the 2-for-1 directory are beginning to open.

To ensure the safety of visitors and staff, many have special measures in place, including pre-booking and limiting the number of visitors.

Before visiting a garden, please contact the garden directly to determine their opening status and any restrictions that may apply.

Please note: we’re unable to keep all individual 2-for-1 garden pages updated, but we will publish the latest details that we have on our weekly updates page from week commencing Monday 8 June, 2020.
