All I can suggest is have that pre-prepared reply as accessible as you can. I use textblaze, a plugin for chrome, and it allows me to save regular replies and access then by typing a sequence that brings them up. iNat is primarily focused on wild organism observations, and given the frequency of new users posting captive and cultivated plants, the community at large will be pre-disposed to flagging anything in a cage as wild. The Identify page thumbnails don’t show the description/notes, so anyone doing annotations or DQA there will not see them. therefore it will be an ongoing annoyance to you, I’m afraid. I myself am coming to iNat from a cultivated plant background, and so I feel your pain in terms of iNat not quite being perfect for what I do :) It’s still pretty cool though.
