What you choose would depend on several things.* You will need to know much light you get where you want to grow your plant(s).* Would it be direct light shining into the room on the plant(s) or a bright room with no direct sun on the plant(s) or a north facing room that doesn't get very bright light?
Do you tend to fuss with your plants and like to water alot or are you the type of person who often forgets to water?* I'm a 'forget to water' person.* :shock:
Do you want plants for a table top, window sill or something large that sits on the floor and looks more like a tree?
What type of look do you like (if you know) as to tropical, structured or even something light and airy?
Once you answer those questions I can give you some ideas with pictures.
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
