Is a window sill direct sunlight

Indoor plants for sunny south-facing windows

What are sun-loving houseplants?

Indoor plants for the sun should get at least four hours of sun a day. These houseplants mostly come from tropical areas or areas with a desert climate, so the plants are well adapted to heat and lots of sun.

General characteristics of plants that can tolerate a sunny spot

A rule of thumb is that plants with small leaves can tolerate the sun better than those with large leaves. If the plants also have hairy or firm leaves, this is another indication that they can withstand sun and heat, as this is a protection against evaporation. Succulents that have firm and thick leaves are a good example of this. Little water evaporates from their leaves. In addition, the thick leaves serve as a water reservoir, so that they can withstand longer periods of drought.

South windows and the influence of the pane of glass

South windows are not just south windows - what sounds strange at first becomes understandable when you think about the insulation of the window panes. Modern windows insulate well so that no heat build-up is to be expected even on hot, sunny days. With older windows, on the other hand, it can get very hot behind the pane. Strongly insulating windows also swallow a lot of the incident light. Behind them it can be too dark even for sun-hungry plants. Here you have to try out a little which plants feel good.

Which houseplants can tolerate full sun?

Here are our recommendations for indoor plants that can stand in full sun and feel really good there.

1. Real aloe (aloe vera)

As a succulent plant, the aloe vera is ideally equipped for a life on a sunny window sill. The plant has thick leaves that are up to 60 centimeters long, with small spikes on the edges. The aloe vera is a very easy to care for houseplant that needs little water. It may only be watered when the soil in the pot is already dry. You can influence the growth with the amount of water you pour. If the plants are watered more often, they will grow faster. The aloe vera can grow very large.

2. Elephant foot (Beaucarnea recurvata)

The elephant foot is a particularly sun-hungry houseplant. Its exotic growth with its thick base and long, overhanging leaves makes it popular with us as a houseplant and has also earned it the further name "bottle tree". The elephant foot grows very slowly and can reach heights of up to 1.5 meters. Caution: the bottle tree is slightly poisonous. Cat owners should therefore keep their hands off him.

3. Miracle shrub, croton (Codiaeum variegatum)

The miracle shrub, also known as the crab flower, is a wonderful houseplant, the colorful leaves of which put many flowers in the shade. The miracle shrub loves a lot of sun. If it is too shady, the branches become very thin and soft. The crab flower belongs to the milkweed family. Their leaves are therefore slightly poisonous. Keep them out of the reach of small children and pets.

4. Column euphorbie (Euphorbia trigona)

The columnar euphorbie, also called cactus-like milkweed, triangular euphorbia or triangular milkweed, like the miracle shrub, is one of the milkweed plants and is also poisonous. The easy-care houseplants grow quickly and can reach heights of up to two meters. They have thick, triangular stems with thorns on the edges. At the top they have small leaves. If the columnar euphoria gets too big for the windowsill or room, you can cut. Always wear gloves when cutting, as the milky sap that escapes will cause skin irritation.

5.Green lily (Chlorophytum comosum)

The robust green lily feels comfortable in a place by the south window. Because of its long, overhanging leaves, it should be grown in a hanging basket or on a pillar. Green lilies do not need a lot of water and can withstand a few days in drought.

6. Madagascar palm (Pachypodium lamerei)

When looking at a Madagascar palm, some will wonder whether they are looking at a cactus or a palm. The answer is neither one nor the other. The plant has a prickly stem and elongated leaves at the top. Incidentally, it throws it off if it is too wet or dry. However, the plant is very easy to care for and can also tolerate dry heating air in winter. But be careful: The Madagascar palm belongs to the dog-poison family and is therefore poisonous in all parts of the plant.

7. Christ thorn (Euphorbia milii)

And another poisonous but very decorative milkweed plant. The thorny shoots are crowned with pretty red flowers. This plant is also very easy to care for, but not for households with small children and pets.

8. Palm Lily (Yucca)

The palm lilies are colloquially called yucca palms, as their growth is reminiscent of that of palm trees. In the right location, easy-care plants can grow very tall and wide. Palm lilies have to be watered sufficiently, but cannot tolerate waterlogging.

9. Flaming Käthchen, Madagascar bell (Kalanchoe blossfeldiana)

The best known are the red flowering Kalanchoes, which gave the Flaming Käthchen her name. There are now also yellow, orange, pink and white flowering varieties. They all feel at home in a sunny window. Kalanchoen can also survive longer periods of drought, but not a permanently wet substrate or even waterlogging. It is therefore important to plant them in a well-drained substrate.

10. Breeding leaves (Kalanchoe daigremontiana)

Like the Flaming Käthchen, the breeding leaf belongs to the genus Kalanchoen and has thick, fleshy leaves. Unlike its relative, it becomes quite large and reaches a stately 150 centimeters. The leaves of the breeding leaf can take on different shades of green on a plant. Brood leaves have long, triangular leaves. The plants form flower panicles on which the red to purple-colored individual flowers hang down like small bells. Because the plant is poisonous, it should not be found in households with young children or pets. You should wear gloves when cutting the plant.

11. Ribbon bush (Homalocladium platycladum)

The band bush is not yet very well known. The shoots of the plant look like someone has flattened them and have constrictions at regular intervals on which the small leaves grow. The plant does not need this, however, as the task of the leaves is taken over by the green, flexible branches. Still, you should watch out for the leaves, because if the ribbon bush sheds them, it is a sign that it is too dry. The ribbon bush can be up to a meter high and very wide. The ribbon bush forms white flowers on the side of the sections, from which red fruits develop.

12. Mother-in-law cactus (Echinocactus grusonii)

The mother-in-law chair cactus is a particularly easy-care cactus and very popular because of its round shape. It is an example of many other cacti that feel comfortable in a south-facing window, such as the old man's head (Cephalocereus senilis) or the bishop's cap (Astrophytum myriostigma). All cacti love a bright, but not all a sunny location. As a rule of thumb, the brighter they are, the better cacti can tolerate sunny locations.

13. Three-masted flowers (Tradescantia)

Tradeskantien are decorative foliage plants that are particularly good in hanging baskets because of their drooping shoots. The three-masted flowers are very easy to care for and can withstand many a care mistake. It is therefore highly recommended for newcomers to plants.

14. Money tree (Crassula ovata)

The money tree with its knobbly, round leaves likes a sunny spot very much. In winter, however, the uncomplicated plant likes to be a little cooler and keeps a slight hibernation.

15. Pea plant (Senecio rowleyanus)

The shoots of this hanging plant look like peas strung on a string. The plant comes from South Africa and is therefore well adapted to heat and lots of light. The plants do not have to be watered often, but then thoroughly. However, excess water must be able to run off, because the plants cannot tolerate waterlogging at all.

16. Bow hemp

Bow hemp is often described as a plant that also grows in darker corners of the room. That's right, but only because this plant is indestructible. It feels more comfortable in sunny locations and also grows better there. If you want to bring your ground hemp to the sunny south window, don't put it in the sun straight away, but give it some time to get used to it.
