Lucky Bamboo
Dracaena sanderiana, known as Ribbon Dracaena, Lucky Bamboo, Belgian Evergreen or sometimes Ribbon Plant, is a species of Dracaena, native to Cameroon in tropical west Africa. It is one of a group of small, shrubby species with slender stems and flexible strap-shaped leaves that grow as understory plants in rainforests. It is an upright shrub growing to 1.5 m tall, with leaves 15-25 cm long and 1.5-4 cm broad at the base. It is marketed in the developed world as a Chinese decorative plant "Lucky Bamboo" (although unrelated to Bamboo and not native to Asia), propagated from short cuttings, usually in water. citation

Bonsai
Bonsai (lit. tree-in-a-tray) is the art of aesthetic miniaturization of trees, or of developing woody or semi-woody plants shaped as trees, by growing them in containers. Cultivation includes techniques for shaping, watering, and repotting in various styles of containers.
'Bonsai' is a Japanese pronunciation of the earlier Chinese term penzai. A 'bon' is a tray-like pot typically used in bonsai culture. The word bonsai is used in the West as an umbrella term for all miniature trees in containers or pots. citation
