She already has a large inventory list.
Teresa, do you mean you want to see your inventory list in alphabetical order? They already are. You can go to your profile page and open one of your lists, say for instance, your daylily list. What I would do to continue adding additional plants is open another window, that way you can go back and forth against what you already added. Not sure if you noticed though, if something is already in your list, it says so on the entry so you can't add it again.
