The gardens at Biddulph Grange Gardens, a National Trust property, have two displays of interest to me: The Stumpery (which I understand was the first ever created) and the Dahlias (when in flower). Here are some views from a visit earlier this year:
Next are some views of the stumpery – this is a display of old tree stumps that are inverted to show the patterns and architecture of the roots. Ferns and other plants are set amongst the roots:
Finally, a nice area is the Lime Avenue to the side of the garden:
This is a place we visit several times a year – it is interesting to see how the garden changes through the year.
