Puzzlement soon made way for delight for visitors and volunteers at a Sheffield community farm when a variety of colourful bouquets appeared.
A number of bunches of flowers were left around Manor Oaks Farm - part of the Manor Lodge attraction - on the morning of May 5
At first staff and volunteers thought they belonged to farm visitors.
But when more were discovered, their curiosity was aroused and they read the cards on the bouquets.
That was when the real purpose of the flowers became clear.
Olivia Duff is a community ranger for Green Estate, which runs the farm and the lodge. She said: "I turned up to work as usual and nothing seemed different until around 9am when I saw a beautiful bouquet outside the blue shed we use for plant sales and information on volunteering.
"I left it alone because I assumed such a beautiful bouquet had an owner who was using the café.
"It wasn’t until later that Paula from the café came up and asked me if I knew about the random bouquets around the site."
The card on the bouquet by the café said: “Free to a loving home. Take me with you please!
"5th May is Lonely Bouquet day. The purpose is to make somebody happy.
"For you or someone you know. Share the flowers if you want.”
The lodge was not the only place where the bouquets appeared in the area, with others spotted in Stocksbridge and Dronfield.
The identity of the person who left the flowers at Manor Oaks Farm remains a mystery. But they brought plenty of happiness to those who saw them.
Olivia said: "I was certainly pleased to see such a kind and thoughtful gesture on site as I am sure other staff members were.
"Visitors to the site seemed to enjoy the flowers greatly and many of the bouquets found new homes with visitors.
"Unfortunately I missed my opportunity to rehome some flowers but it certainly put a smile on my face to see such a lovely act of kindness."
