This was the alchemy guild item a couple of days ago. Unfortunately the upper elshimo region was controlled by beastmen and none of the auction houses carried a cattleya so I couldn't make it and find out how much it was worth.
I swear I spent about 2hrs looking for that stupid flower in bazaars as well.
FullMetal Alchemist is the best show ever, but i can't stop playing FFXI long enough to watch it! =P Fullmetal Alchemist's Law of Equivalent Exchange: To obtain something, something of equal value must be lost.
