I put lilies in a tall vase last week. They all bent to one side by the next day.
I used standard floral foam for a large wedding arch installation. The bride saw a post about how it's not good for the environment. She got mad and canceled her whole order with me. Now I only use biodegradable foam, but that mistake cost me a lot.
I was at a house call to set up some table pieces for a dinner party. The lady had a big parrot in a cage near the dining area. While I was working, the bird got out and flew right onto my work table. It started picking at the petals and dropping them everywhere. The owner was trying to catch it, but the bird just squawked and moved to another bunch. I had to shield the flowers with my arms while she got the parrot back. We both ended up laughing once the bird was safe. Now I ask about pets before I bring in any fresh blooms. That bird had better taste in flowers than some of my clients, lol.
It's in half the arrangements I make, but knowing it won't break down ever really gets to me. We just throw it all away after the wedding.
It just sits in landfills and never goes away. We should be using moss or reusable supports instead.
