"Hello, I'm an artist putting on an event in London at the end of March and I'm looking for long stemmed British organic edible flowers. Can you help?"
"Well I'd love to but I fear it just may not be possible then."
"I thought roses would be lovely."
"Yes. I think you might be hard put to find organic roses anywhere in the world in March and definitely not in UK."
"Ah. Well I have a list here of all the edible flowers I might like. Shall I send it to you?"
"It's very thoughtful of you, but I think I only have poisonous long stemmed flowers then."
Anyone wanting to munch on tulips, hellebores, euphorbia.........? I suppose ranunculus might just not be inedible but I don't think I'd want to try. Two years ago I had to do 12 identical edible long stemmed bouquets for a film prop. That was hard enough in June.
