I had to look it up !! there were an unusual amount of walnut trees, whilst on site I found no guide to the tree planting , below a couple of copy and paste found since.
''In 1987 a collection of walnuts was started that are now mainly planted in the pleasure grounds and contains over 60 species. New varieties are constantly added, recently a collection of Juglans regia form America.''
''Brief history of siteThe gardens at Wimpole have a history of Walnut planting with Kip's engraving of 1709 showing the avenue planted with regia, nigra and cinerea.''
''We were walked round the National Collection of walnuts, and it was amazing to see thedifferent shape and size trees that this encompasses. As he described the characteristics of the different walnuts, Philip Whaites referred occasionally to Clive Simms and his book the ‘Nutshell Book to Growing Walnuts’'
''There was also an orchard with many varieties of apple.
Unfortunately I didn’t know that a National Walnut Collection is also at Wimpole, should have paid more attention before I went. Still always good to have another reason to visit!.''
one for the diary perhaps 'Event - Wimpole Hall

agg221 your daughter can be excused the farm and animals are a brilliant place to discover! for both adults and children you need a t least a full day there before even going out into the parkland, then you can start exploring some veteran trees, I understand mature elm were the main spp. with a massive avenue to the south, big enough for the American air force to park / hide their planes under the Elm Trees, unfortunately I could find no pictures of this, I will have to return, I understand there is a green wood working show there this week end http://www.nationaltrust.org.uk/wimpole-estate/things-to-see-and-do/events/
