In the US, the vets organization used to sell plastc poppies for people to wear on Veterans Day. I haven’t seen that happening for a generation now. Always thought it was a nice way to honor our veterans. Guess it’s more a custom of Canada and the Commonwealth nations.
I’ve only seen red crape paper poppies here in the Northeast. I buy one every year. I prefer the British poppy - made of a kind of plastic/vinyl. Prettier design as well.
