Secret gardens

I and a friend visited the 12 secret gardens of Topsham today which were open in aid of the local Museum. we started at the museum where there was a plant stall and worked backwards by numerical entries. We thought the second garden we saw outshone all the others and it was here I spotted this flower which is one of the hardy geraniums, a sterile one and I was able to buy one. Most of the gardens were walled gardens and some were extremely small and quirky.
