Question
Every year I get as a gift potted Hyacinth I would like to plant them outside can I, if so when  

Answer
Hi Bonnie,
Thanx for your question.  The potted hyacinth has been artificially forced to bloom.  This requires a large amount of energy on the plants part and is usually fatal to the plant.  You can plant it now if you like and take your chances.  Good luck!  I hope this helps.
