This is great. I'm going to star the thread. After it's up for a few weeks, if you don't want to turn it into a Tip or Idea yourself, I'll propose a draft and try for "concise" ... then ask for corrections and shortening advice.
I wish the plant height and plant width fields could be sliders so we could search for "30-40 inches" and catch them all. But then we couldn't enter things like "3 to 5 feet".
