Zhigang Li winner of International Garden Photographer Wildflower Landscapes category
The overall winner of the International Garden Photographer of the Year was named as Albert Ceolan of South Tyrol, Italy. Ceolan won £7,500 and said: "The thought that one of my images will be shown as overall winner in these mythical gardens fills me with enthusiasm and pride."
The image (seen above) is of the destruction of the Vaia Storm in the Dolomites in South Tyrol, Italy. It was entered in the new Plants and Planet category.
Tyrone McGlinchey, head judge said: "Albert has documented a scene which is simultaneously shocking as it is well composed. The photo shows both the natural destruction by storm Vaia and the remaining trees, symbolising hope."
