Plants need sunlight to be able to thrive. They also need a certain amount of oxygen, though not much. Other plants are thought to be nuisance aquatic species. Various plants need several types of containers.
Green craft project idea - Repurpose a tuna can and clothes pins to make a flower pot or candle holders. Would be cute to do with a kid to work on fine motor skills. Would be cute for grandparents or as a Mothers Day gift! =) mothers day present :)
