I talked to our Greenery chairman today and she said we ordered from a place called Sherwood Forest. Don't have the website at this moment, but I bet it could be found with a search.
For poinsettias, she ordered locally from a wholesale nursery.
For the last couple of year we have done a Holdiay Greenery (wreaths) fundraiser. I am not sure I want to stay with the company we use, so if anyone else does one of these and your happy with the folks you use please let me know who they are! Thanks!!!
