Painting the roses red - just found of my other surprise thanks to his big mouth room mate :D. roses painted red like in alice in wonderland :'D. good thing his surprise is almost as well thought out, thanks to some brilliant people >:D.
Split the stems into strands, place each one in food colouring and get rainbow flowers. Only catch must have a very large round stem in order to achieve this. Or you can inject white roses as they grow.
This reminds me of one red rose I had blooming out of 3 feet of snow by my lamp post when I lived on Long Island.My grandma always said it meant something -) It didn't have any frost on it tho.it was a fresh red rose -)
