Lucky bamboo

some more tips..

Bamboo is an easy houseplant to grow, and it requires little care. Just remove the string to keep it from choking the plant as it grows and be sure it gets plenty of indirect sunlight. Direct sunlight can cause yellowing of the stalks.

If your plant came in a pot filled with tiny pebbles, simply replenish the water as it evaporates, keeping it at about an inch from the base of the stalks. Change the water completely from time to time to keep it clean. If it's planted in soil, water it when the soil surface becomes dry. Using chlorinated, fluorinated tap water might cause the stalks to turn yellow, so let the water sit in a cup overnight at room temperature before watering. This will allow the chemicals to dissipate. You can use spring water instead, if you prefer. And keep the bamboo away from pets; it's toxic.
