"Going Out On A Limb" Teacher's Gift

I really feel that the whole "thanks for making me bloom" idea gets used way too much when giving flowers, so I thought I would change it up a little. Instead, I put "I wouldn't be going out on a limb by saying that you are a super teacher"!  Get it? LIMB? I figure you could use any flowered plant that can also be classified as a tree.  I love hydrangeas, and really wish that this one had been in bloom for this picture. At least it will be nice and pretty in bloom when given as a gift.
