Can an outdoor plant survive without sunlight

Plants for the bathroom without a window: 10 green plants

Bathrooms without a window are rare, but they do exist. A little sunlight only penetrates when the door is opened. They also have to be artificially lit during the day. The air in it can only circulate with the help of technology. Can such a room be a habitat for plants? Which green plants will survive longer in the bathroom and, with our support, will even grow happily?


No life without light

Let's not kid ourselves: the only plants that can be completely without light are artificial plants. Because plastic doesn't grow. Living green plants, however, always require a minimum amount of brightness. Therefore, not a single species of plant can be listed here for which a bathroom without a window is suitable. In a room without a window, any plant will suffer. It is only a matter of time before it dies completely.

Lamp instead of sunlight

It is still feasible to set up living green plants in the bathroom without a window. A special plant lamp makes this possible. It provides the light spectrum that plants need for photosynthesis.

  • not all light bulbs are suitable
  • use special grow lamps
  • Adjust the amount of light to the plants
  • choose a sufficiently powerful lamp
  • alternatively use several lamps
  • place near the green plants
  • simulate the natural day and night rhythm with a timer
  • Tropical plants need 10-12 hours of light a day

Unlike sunlight, this light is not available to us free of charge. In addition to purchasing the lamp, you also have to pay for the electricity you use every day. Depending on the lamp, 3-7 euros per month can be incurred.

Shade and moisture

For a bathroom without a window, but with a special plant lamp, green plants that thrive well in the shade are primarily considered. Because seldom will a plant lamp completely satisfy sun-loving plants. High humidity is a second factor that we deal with in a bathroom. Because with every shower, the air is enriched with plenty of moisture. The following list therefore consists of plants that like humidity and at the same time need little light.

Mountain palm

The mountain palm owes its popularity as a houseplant, among other things, to the fact that it is content with shady locations. This is because it is originally a plant of the rainforest, where it thrives in the shade of tall trees. The mountain palm will also grow in an artificially lit bath. Otherwise it belongs to the easy-care green plants. In a bath with high humidity, the leaf fronds do not need to be sprayed with water, as is otherwise recommended. However, a full-grown palm is only suitable for large baths, as it grows expansively.

Tip: A mountain palm is ideal for hydroponics. Because she not only likes moist air, but also wet roots. With hydroponics, you don't have to think about watering that often.

Dragon tree

Dragon trees come from sunny parts of the world. However, they cannot tolerate direct solar radiation. Well, you definitely won't get them in a bathroom without a window. The light quality of a shady to partially shaded location can be easily achieved for the dragon tree with a plant lamp. While the spray bottle has to be used regularly in other rooms during its cultivation, it gets its vital moisture in the bathroom by the way. He won't feel the hated draft here either. Since dragon trees grow towards the light, it will mainly develop upwards towards the plant lamp. Due to this expected slim shape, the dragon tree will not take up too much valuable space.


The Efeutute can tolerate the sun, but it is by no means an obligation. Even in the shade, this plant is ready to thrive. She does not like to feel a draft or a great deal of cold. In this regard, she is in good hands in a dark bathroom. The ideal humidity for them is 50 to 65%. This plant has several advantages:

  • can grow as a climbing plant
  • also suitable as a hanging plant
  • ideal for bathrooms with little space
  • the tendrils are very long
  • can act like room dividers
Note: The darker the ivy, the more it loses its striking leaf markings. But it is still a beautiful sight even with green leaves.

A leaf

The leaf also originally comes from the rainforest. The high humidity of the bathroom won't mind. This plant is one of the few green plants that even standing moisture does not bother. The single sheet will also like the warmth in the bathroom, because it prefers temperatures of 18 to 25 ° C all year round. If the light of the plant lamp is enough for her, the single leaf will even form beautiful white bracts that are reminiscent of flowers.

Tip: If the white bracts turn green or even brown, this indicates a lack of light. In this case, optimize the performance of the plant lamp.

Maidenhair fern

The ideal location for maidenhair fern is the tropical rainforest of South America. In this country, a shady location with high humidity suits him best. This description applies to a bathroom without a window, provided that a plant lamp of the green plants regularly brings light into it. The plant grows bushy and is up to half a meter high. However, it should not get splashed with water very often, otherwise its leaves will turn brown. Only water with little lime should be used for watering.

Antler fern

In the nature of Australia the antler fern grows on trees. This refers to tall trees in the rainforest, in whose forks of branches the plant seeks a place to live. The rays of the sun cannot penetrate the canopy of the trees, so the antler fern is used to shade. In the bathroom, you need to give it a specific way to hang from the ceiling. The leaves resemble deer antlers, which is easy to see from the name.

Lucky feather

The lucky feather is considered to be easy to care for and insensitive. It also thrives in shady places, but like all living green plants, it needs a minimum level of brightness. If there is too little light in your bathroom, your growth will stall. But even then, the Zamioculcas does not have to leave the wet room, because the problem can easily be solved with a new plant lamp. The lucky feather is up to one meter high. It is considered to be indestructible, but it must not be poured excessively.

Green lilies

The green lily has thin long leaves that are reminiscent of giant grass. She likes a bright location and absolutely needs sufficient additional lighting from a plant lamp in the bathroom without a window. Why it is listed as a suitable plant for the bathroom is due to its undemanding attitude towards maintenance.

  • takes up little space
  • can grow in a hanging pot
  • there are pure green and green and white striped varieties
  • the darker it is, the more the light stripes will disappear

Basket margin

The basket marante is a tropical plant that is well acquainted with both shade and high humidity. Different shades of green create an attractive pattern on the leaves. This green plant likes warm and humid places all the time and is at least spoiled in this regard by the bathroom. But her owner must not neglect her either, because this exotic requires a lot of care:

  • Keep the soil moist at all times
  • Fertilize every two weeks during the growing season
  • repot every spring
Note: If the beautiful pattern of the leaves fades over the years, it is not a sign of poor care. That is part of their existence. Each specimen of this plant species will at some point only have pure green leaves.

Cobbler palm

The cobbler palm is also known as the butcher palm. It originally comes from Asia, but also proves to be easy to care for in this country. She tolerates a lot of deviations in her living conditions. The cobbler palm is therefore one of the green plants that are suitable for people without green fingers and for beginners. It grows without a trunk, sprouts from the woody rhizome. The bushy growth can reach a height of 80 cm.

  • it grows more slowly in dark corners
  • patterned varieties lose their markings there

Observe plants

Plants are living beings, each specimen grows individually. Over time, they get bigger, and so do their demands. If the plant light was sufficient at the beginning, this can change in a later phase. You should therefore carefully watch the development of the green plants in the dark bathroom. Slow growth, leaf changes and possibly the absence of flowers could be signs that you are suffering. Then either they have to leave the bathroom or the living conditions have to be optimized. For example, with an additional plant lamp.
