Not all indoor plants feel comfortable in a sunny south-facing window. We present nine plants that have no problems with the blazing sun.
Greening a window still on a south-facing window with house plants? It doesn’t seem that easy at all. The sunshine is particularly intense here at lunchtime and during the summer months. Not all indoor plants can cope with so much sun: Plants for dark corners would quickly get burned here. Fortunately, there are some plants, including cacti and other succulents, that are used to a lot of suns from their home. In our house, too, they want to be in the direct sun.

Which houseplants can take a lot of suns?
With their fleshy, thickened, water-storing leaves, succulents reveal that they have no problems with drought and heat. Most species come from very barren areas that are exposed to the blazing sun. Plants with tough, leathery leaves with a waxy surface are also heat-tolerant.
Some cacti, such as the old man’s head, protect their leaves from strong sunlight with their hair. Whether flower or leaf ornamental plants: the following nine house plants like to be in the sun – and need them to thrive. Because a lack of sunlight quickly leads to poor growth among sunbathers.
Aloe vera is a classic among sun-loving indoor plants. As in its tropical home, the succulent plant loves a sunny spot in our rooms. Since the light conditions on the balcony and terrace are much better in summer, the plant can also move outside during this time of year.
In winter, the houseplant likes to be cooler, but also as bright as possible. The green plant needs little water and can be kept almost dry in winter. Only in summer is it supplied with a low-dose cactus fertilizer. Tip: It is best to pour over the coaster so that no water gets inside the rosette.
Among the milkweed family (Euphorbiaceae), the Christ thorn (Euphorbia milii) is a true sun lover. In a bright, sunny spot, the succulent shrub adorns itself with its colorful bracts in the winter months. A location at the south window is ideal for the indoor plants – in summer they can also be moved to a warm, sheltered place outdoors.
Make sure you only water the milkweed plants sparingly – too much of a good thing quickly leads to root rot. Caution should also be exercised when cutting and repotting: all euphorbias contain a poisonous milky sap, and it is easy to injure yourself on the thorny branches of the plants.
Echeveria from the thick-leaf family is used to a lot of sun from the arid regions of Central and South America. To protect against strong sunlight, the leaves of some species are covered with a layer of wax, others protect themselves with thick, felted hair. The rosette from Echeveria agavoides, which is only about 15 centimeters high, is particularly beautiful.
Give the decorative houseplant a very bright, sunny place all year round. In summer the plant likes to be warm, in winter it is a bit cooler at 15 degrees Celsius. The care of the succulent is uncomplicated: Even in summer you only have to water the echeveria sparingly and only provide it with cactus fertilizer once a month.
If you are looking for sun-loving indoor plants, you will also find suitable representatives among the cacti. The prickly pear (Opuntia ficus-indica), which occurs naturally in dry subtropics, can withstand a lot of light and sun. So that the plant adorns itself with bright yellow flowers from spring to summer, it also needs a sunny, warm place in the room – the plant likes to stand by the south window.
Temperatures should be around 18 to 25 degrees Celsius and around eight degrees Celsius in winter. You can use the finger test to check whether new watering is necessary. Beware of the inconspicuous thorns of the houseplants!
Even if the name immediately suggests real palm trees: The Madagascar palm (Pachypodium lamerei) is also a succulent plant. She knows a lot of sun from her homeland Madagascar – she feels at home all year round in a south-facing window at 18 to 30 degrees Celsius. With a little luck, you can see white star blossoms in older houseplants that are already at least three feet tall.
Watering is rarely necessary as the plants can store water in their trunk and roots. The houseplants need a larger pot about every two years – to protect them from the thorns, it is essential to wear gloves when repotting.
Among the palm lilies, the yucca palm (Yucca elephantipes) is the ideal houseplant for direct sun. The bulbous, thickened stems and the sword-shaped leaves, which usually overhang elegantly, are characteristic of the plants. The location for the indoor plants should be full sun and airy all year round. From May to October, you will also feel comfortable on the balcony or terrace.
The substrate for the yucca palm is well-drained, nutrient-rich palm or green plant soil. It is best to check with a finger test before watering the houseplants whether the top layer of soil has dried off. From May to September they are fertilized every two weeks.
Among the cacti, the mother-in-law (Echinocactus grusonii) can withstand a lot of suns. With its spherical growth and yellow spines, the plant adorns large windows facing south. Particularly practical: the cactus protects itself from sunburn with its dense yellow felt. In summer, however, do not put the houseplants outside straight away: Before moving outside, it is better to get used to the plants in direct sunlight. To get an older cactus to bloom, place it a little cooler in winter at around ten degrees Celsius.
Birds of paradise (Strelitzia reginae) are known to many as exotic cut flowers, but they can also be cultivated as indoor plants. Sufficient light is crucial for the well-being of the South African beauties: Full sun promotes the formation of impressive flowers. Make sure to water the houseplants sufficiently during the growth phase and to fertilize them once a month. in winter, a bright but cool location with temperatures between 10 and 15 degrees Celsius is still ideal. Tip: As soon as the first flowers appear, you should not move the plants anymore, otherwise the flowers will not open any further.
Strelitzia: Heavenly beautiful
The Strelitzia, also known as the bird of paradise flower, is mainly used as a cut flower. The exotic plant with the spectacular flowers also thrives in pots. Here you can read everything you need to know about planting and caring for your own four walls.
Desert roses (Adenium obesum) as easy-care indoor plants for the blazing sun are still a little insider tip. The steppe plants also cope wonderfully with heat and drought. In a sunny, warm place, the plants open their colorful flowers in spring.
Tip: So that the houseplants do not grow one-sided towards the sun, they should be rotated regularly at their window seat. In winter the plants need a break in which they are kept cooler and kept dry. In the following spring, the time has come again: in the warm sun, they enchant us with their bright flowers.
