I'm only an alien in my mind :P

I'm not really understanding what you are asking. There are many lists in the guide section, so I don't know which you are using. Also, you mentioned 4 different types of plants, so I'm not sure which one you are attempting to get.

If this helps, stay *away* from the mutation liquid until you know exactly how it all works. That just confuses things.

When a seed appears in the plant's information box, it is the seed that you just created (either by self pollination, cross pollination, or mutation)
