Great post and virtual visit, I have never been to a flower show. It's ironic as I've worked within 300 feet from the door of a local conservatory that hosts such events as our state AHS Daylily events. I've only visited the conservatory once in all the years I've worked near or driven by.
When I think of flower shows I think of Aunt Bee from The Andy Griffith Show. Title is "It's Only a Rose" and free for (re) view on youtube and tvland. If you're feeling nostalgic it's good episode, I watched it earlier after searching the title. LOL.
Thanks for posting, I'll have to watch for something similar to attend this year. I've never seen flowers judged. I judge my own but it should prove interesting. I don't hybridize (yet) but I'd enjoy the show for sure. Even roses.
