The sculptures around the Himalayan Garden are eye-catching. Here are some I particularly liked.
Above is Samara (Rebecca Newnham) - made of glass over a fibreglass and steel body, and based on the helical flight of a sycamore seed.
Above is Ribbon Red (left) and Red Scarf (right), both by Carol Peace.
Below is The Swift (Hamish Mackie).
And finally, below: Pinnacle (Giles Raynor) - a copper spiral fountain around which water spins.
