It belongs to the genus & quot; Pogonatherum P.Beauv & quot ;.


The room-bamboo does not have many varieties that are commercially available. Widely used is the cultivar "Pogonatherum paniceum Monica". It is the plant that is often found on the market.

There is also real bamboo, which is called a room bamboo. This actually comes from the bamboo variety, but is much smaller. Often, this plant is also called "lucky bamboo". but is not associated with & quot; Pogonatherum paniceum & quot;


The room bamboo is mostly used as ornamental and indoor plant in all areas of home, office and public spaces. But also as a cat grass he finds his use. Because of its nature, hobby zoologists can also use it as a reptile food. Seychelles grass is also very popular in floristry. Its leaves have a particularly long shelf life after cutting. Therefore, due to its fresh appearance, it is often used as a green ornament in bouquets.

Appearance, inflorescence and flowering

The room bamboo has a creeping root system on which the branches and leaves form. The plant can grow up to 60 centimeters high. It has (light) green and mostly upright stalks. Below, these are not branched and hard. Above, the ornamental grass forms branched clumps. The leaves there are long and thin - they resemble a lancet. Some grow up, others depend on growth a bit too. They can be up to 5.5 inches long and 0.4 inches wide. When the room bamboo flowers, it produces yellow grapes that are up to 3 cm long and occur in pairs. Seeds are found in ears of corn.


As the name implies, the room bamboo is a plant for the interior. It can be used both in the rooms, under certain circumstances but also on balcony and terrace plant. It is important that she receives a sunny location. Besides, she always needs it warm. Temperatures between 20 and 25 degrees are optimal. That's why it can be put outdoors during the summer months. But it should also be moist. Bathroom and kitchen are also suitable places. At the earth, the potted plant is not particularly demanding, commercial soil is completely sufficient. Since the room bamboo does not tolerate waterlogging, the floor must be permeable. This can therefore be loosened up with granules or sand. Since the plants have a high nutrient requirement, the clever gardener selects a pre-fertilized substrate here. The pH of the soil should be between 5.5 and 6.5.

Plants and propagate

The planting of the Zimmerbambus can be done by young plants, which are available at very favorable prices in the trade. But also sowing by seeds is possible. These are obtained from the ears of the plant, but also the trade holds suitable seeds ready. The sowing should take place in a warm and sunny location and is possible all year round. The plant needs a lot of water, so seeds (or whole ears) should be soaked in the same for one hour before sowing. Then they germinate within a few days. The sowing depth in the cultivation soil is a maximum of two to three centimeters. At high temperatures and low humidity should be covered with foil. This prevents drying out. If the shoots are about ten centimeters high, then they can be put in pots.

For propagation also root outcrops or the possibility of root division are available. In the former, strong side shoots are separated from the root ball and cultured in a glass of water. However, this variant has the least chance of success. The division of the root is considered simpler. The root ball must be lifted out of the pot and pulled apart slightly. The rhizomes separate almost automatically from each other. Dead shoots are removed at the same time. The two separate plants are now also planted separately. In order to facilitate the growth, the soil must be kept very moist.

The water glass with roots should be dark to improve the chances of success. High temperatures are an advantage here.


Watering and fertilizing

The room bamboo is considered to be easy to clean. However, just when casting the mediocrity must be found. Because both dehydration and waterlogging damage the plant. The former must not occur for a short time, otherwise significant damage may already occur. Therefore, it is also advisable to regularly spray the plant with water to spray or shower. This is necessary especially in rooms with low humidity. The Zimmerbambus loves lime-poor water. Therefore, rainwater from the barrel is optimal. If tap water has to be used, this should be left out a little bit beforehand. Fertilization is also necessary on a regular basis. From spring to autumn, a fertilizer should be given every two to four weeks. In winter it is not necessary. The darkness of this time of year sets the plant in its resting phase even in the warm room temperatures.

The bathroom or kitchen is usually very humid. Here should not be poured too much. In case of prolonged absence, an automatic pouring device is recommended for the room bamboo.

Cutting and caring properly

In many cases, the room bamboo does not have to be cut. However, it can also become too big or too lush. Then the owner should thin out with scissors. Also dry and dead leaves and stalks should be removed regularly. This can happen all year except in winter. During this period, no new shoots would be formed. The incision can also help with the infestation of diseases or pests. Once a year, the Zimmerbambus must be repotted. This should happen in the spring. Reason are the densely formed roots, which can fill the pot on the one hand, but also knot with each other. In addition, it needs new soil, as this is quickly consumed by the frequent pouring. When repotting a larger pot should be selected. This is filled with fresh earth. The soil can be directly enriched with fertilizer. The root ball should first be rinsed off after removal and then freed from knotted parts. After potting, sufficient watering is important. The stems of the plant should also be moistened.

The augmentation can take place simultaneously with the annual repotting. The gardener only has to work once, because the roots have to be removed from the vessel one way or the other.

Toxicity and Ingredients

As a young plant, the room bamboo may be poisonous. Therefore, it should be placed at this stage out of the reach of children and pets. When the plant grows up, it loses its toxicity. However, she gains in injury. Because the stalks and leaf edges can become sharp. At them it is easy to cut. Therefore, the offer of the plant for cats as a cat grass should be treated with caution.


The Zimmerbambus must overwinter inside. He is allowed to go outside in summer. Because the plant needs warm temperatures. In winter, they should not sink below 18 degrees Celsius. A dark location puts the room bamboo in the resting phase. So normal temperatures are possible.

Susceptibility to diseases and pests

One of the biggest enemies of ornamental grass is rot. This is mainly caused by waterlogging. Especially in winter, the danger is particularly high, since the plant is in the resting phase and requires less moisture. If the room is not ventilated enough, rot can quickly develop. If this is the case, the affected areas must be removed. The earth should also be replaced if the plant is to be saved. Natural pests for the Zimmerbambus are mainly spider mites and aphids. In many cases, they only make one stop on their journey from plant to plant. Here commercially available means should be used to combat them. In most cases, the infestation is not permanent. Care mistakes are often blamed for damage as the room bamboo is considered robust and resistant. Therefore, it is important to check the casting behavior in dry, brown or infested plants.
