Odd Sentiments – Square Odds

….found these ‘sentiments’ hanging in the bushes down at the park

Sentiments is the word a passerby used when I pointed out these wreaths hanging from the shrubs at the edge of the park. What I found even more odd was that each wreath had a ring either hanging on the wreath or hanging on a branch close by. I have no idea what the sentiment symbolizes or whom it represents. Has anyone out there seen something like this before and do you know what they represent?
