We could get some names going for the different tiers and things. I do like the way you define the differences between them, such as the magical properties. You have a good steady process, on something that has not really been touched on as far as the bazaar or anything has gone. Certainly I would like to see these be developed further as part of proper Althanas herbology.

Seperating them out into netural etc is really good. So you could have a neutral Teir 2, that is a hard plant to keep but is just at its core a pretty flower. You certainly have put a lot of work into this and it would be good to develop some examples of all of these perhaps. Maybe some quests with Nevin to go and discover the darker ones. A place to start would be the Red Forest where there are a number of dangerous plants already in the lore. Because of the state of the Red Forest these can be extremely volatile and dangerous, so would look to fit into your "Aggressive" catagories. I really look forward to seeing the work you do with this.
