I also walked around the outside gardens during my visit to the Gothenburg Botanical Gardens on Saturday 25th January 2020. In the mild weather, there were many people out walking and running in the garden. Here’s an album of pictures of edibles and other interesting plants and a video of the large Actinidia arguta in the Asiatic woodland garden.
