Pots can act as a highlight to the plant they are holding, much in the same way a picture frame can add to the picture. Two ways of using pots inside is to plant into the pot and use a saucer underneath or a cover pot which doesn't have a drainage hole and is sealed to protect whatever surface it's on.The plant sits in it's plastic pot and is lifted out and watered at the sink and returned to the cover pot.Both methods have the health of the plant in mind as well as adding to the look of the room or balcony.
