One of my favourite areas of Hampton Court Palace Flower Show - although I'm not clever enough to understand it - are the conceptual gardens. A series of gardens that 'push the boundaries of garden design' - which is, I guess, why I can't understand them!

This year, my favourite is the It's Hard To See garden by Rebecca Butterworth, Victoria Pustygina and Ludovica Ginanneschi.
It's a simple 'garden' that is sunk into the ground. The concept is complicated, so read the description on the RHS website. If you can understand it please let me know!
