What are the most costly flowers?

The most costly flowers are orchids; a Lady Slipper orchid or a Catalan orchid would be $4.50 a stem at the market, which would retail about $12-$15. In New York, orchids are $20 a stem. There are also Vanda orchids. Sometimes it depends on the rarity of the flower. Something will come on the market that you've never seen before and it will have a high market price: it's just economics. For a brand new flower, they'll retail that flower for $20 for one blossom, which is insane.
