Lucky bamboo is well known for being very easy to grow and maintain. When they are grown in water they can be left for a few weeks without having any health problems, although this water should really be replaced every 7 days. To grow and maintain a good healthy plant it is much better to grow them within a soil pot.
Dracaena braunii plants grow at their best in a pot with soil and live longer lives, however, many are grown in glass type vases which does give them a pretty cool minimalistic look. They are also grown in aquariums and sold in pet shops submersed in water or some shoots just above the water, but this is not the correct way of growing them and they can rot.
