I hope the petals of your Nitidisimum arrive at the show without withering---it's difficult to transport the long-tailed phrags. I grow a lot of the long-tails, and I have an assortment of cardboard box "coffins" that I use...they're long, narrow cardboard boxes filled with pillow batting or shredded florist paper. I put a plastic bag around the pot to contain the potting mix and then lay the phrag down in the box, arranging the petals and sepals so that they are pillowed by the shredded paper or batting. Petals arrive in good condition without the shriveling that usually occurs when petals are left to dangle and sway in the box as the car goes to the show or judging. My friends tease me about my phrag coffins, but they really work well.
