I hope you'll check out the garden clubs in your area, Cameron. Go to the garden show and you'll see that you most likely already have plants that are "show worthy." I start thinking in February about what I might enter in the June show!
I "googled" Plano garden clubs and came up with a few in your area. Just go as a guest and see which one would be a good fit. Dallas and Arlington both have very active garden clubs....mostly men, too. (I'm grinning as I write because The Garden Club of Austin used to be The Men's Garden Club of Austin until all us women started joining!).
