Hi Gerry,
It was around 2000, just before the first rust scare. Both of my best daylily friends, John Rice and Joe Kunkel, had one...and they were truly magical places to visit. I had drawn up plans for one by the side of my garage, and Joe came up from KY for a visit. He said that a greenhouse needs constant attention, and that I would end up resenting it. This was before I had any of my grandkids, and I am so thankful now that my time is free for them.
I am not saying that folks should not have greenhouses. Joe just understood that I should not be one of those folks...lol.
