It’s been a couple’o jobs ago, but a couple three years ago, Daughter#2 had a job at Green Circle Growers. The reason that I mention this is that they had a variety of orchid….my thumb is brown, so I can’t tell you what it might have been….that grows white, but that they turn into the various colors by feeding it colored water at the right time. The orchids they grew there were incredible. Their orchids take about 18 months between getting them started and having them ready to ship out the door. All told, they have 150 acres of greenhouse. I can barely get the lovely Mrs. azlib out of our local nursery, and when she found herself in a commercial grade greenhouse, she thought she’d died and gone to heaven. I’ve attached a picture of their poinsettia room.
