Put it in a ziplock bag - it will last.

Thanks; that was exactly what I decided to try. We'll see soon if it made it.

If you need it to last fr more than 3 days - take a small piece of tissue paper, wet it up, wrap the end of the stem with it, wrap it with foil and put it in a ziplock baggie. Inflate the baggie and then zip it to reduce bruising. People send leaves across Atlantic - and they arrive OK.
