While the search functions are useful, I often have needs to access the ENTIRE listing of the Plant Finder so a quick link to it on the main page would be extremely useful instead of the laborious search for individual species via the search strings.
That doesn't work either. I know that at least Ludwigia palustris isn't there when you do that.
I agree that you should be able to view them all at once. You know how you go into a store to buy something else and end up finding something new instead that you like? I believe the plant finder should be similar.
I have chosen "aquarium plants" to get most of them and then "aquarium and pond plants" to get the rest. It is almost as quick as a view all choice would be. I wonder a bit how some plants got chosen for one or the other grouping, but it isn't important to me.
