If you get a Satchel of Chilled Goods that has Burning Blossom in it, you can leave the blossoms in the bag. Come 4.2 with major patches often the contents of containers is reset. This should let you open the bag again in 4.2 and give you extra chances for the rare items. This worked for me with the Sack of Frosty Treasures in WoLK, I would take the badges out and leave the gold in them, when 4.0.1 hit I opened them again and took out some fresh justice points and other loot.
