Ray Aralie or Zimmeraralie - grooming, marveling and multiplying

It is especially popular in the office or on the windowsill. The ray artery is a welcome houseplant that is easy to maintain and especially useful as an air freshener. Their leaves make them decorative and practical too. The following lines are to be found in planting, care and location.


The Schefflera belongs to the family Araliaceae (Araliaceae). Depending on the genus and variety, it comes from the Asian or Australian tropics. Common countries of origin besides Australia are Japan, Thailand, China or Taiwan. The genus name owes its Araliengewächs to the botanist Jacob Christian Scheffler, who lived in the 18th century.

Appearance, inflorescence and flowering

In their homeland they grow as trees, some species are also lianas or epiphytes. In this country, radiation artery is more likely to be considered an evergreen shrub. Characteristic are the leaves, which are arranged radially. The leaves are often oblong oval, olive green and shine. Some can also be variegated. They are up to 30 inches long. The plant also owes its name to them. The Radiation Aralite naturally produces red colored flowers in the months of April and May, local varieties can shine with white flowers. In them, drupes are formed, which usually contain five to eleven seeds.

In the wild and at home, the ray-artery blossoms. With domestic house plants a bloom is to be expected only rarely and under particularly tropical conditions.


The genus extent is evaluated differently with Botaniker and throws up again and again new numbers and kinds. Some experts include all kinship groups, others only species-poor genera. So the species number varies from over 500 to 1100. In our latitudes, the following five forms in particular are frequently found.

  • Large-leaved Schefflera (Schefflera actinophylla)
  • Small-leaved Schefflera (Schefflera arboricola)
  • Narrow-leaved Schefflera (Schefflera elegantissima)
  • Schefflera (Schefflera elegantissima 'Castor')
  • Schefflera (Schefflera veitchii)

The large-leaved Schefflera is also called the varnish leaf or fingeraralie. This plant is native to northeast Australia and New Guinea and can reach heights between 30 and 200 centimeters. Their characteristic is the upright trunk and the large leaves, which come along oblong oval. In older plants, they can easily overhang. The small-leaved Schefflera, on the other hand, is a sparsely branched shrub from Taiwan. The leaves are usually dark green, also variegated in rarer mutations. This Schefflera variety grows only between 30 and 150 centimeters high.

The narrow-leaved Schefflera is also called Fingeraralie, which originates from New Caledonia. The leaf areas are narrow and especially dark. Their stature height can be between 20 and 80 centimeters. The dense-leaved aralia is characterized by only short distances between the leaves and therefore offers a dense habit. Their leaves are also rather broad and dark green. It can grow between 20 and 40 centimeters tall. The broadleaf Schefflera is also native to New Caledonia and has relatively broad single leaves in green shiny optics. This variety grows up to a meter tall.


Radiation Aralia is particularly popular as a houseplant, as it is considered to be particularly robust. So she often finds herself in offices as hydroponics or on the windowsill in her own four walls. The evergreen plant is not only a popular ornamental plant, it also ensures a good indoor climate. Their large and numerous leaves act as air fresheners - they filter pollutants such as the smoke from the cigarette or formaldehyde from the air.


Above all, one thing is needed for the attitude of the ray artery: light. Schefflera varieties usually love light to half-shady locations. Important for the owner is to avoid direct sunlight during lunchtime. Because this can cause burns. The sunlight is advantageous during the morning and afternoon hours - east or west windows are therefore most favorable for the houseplant. Dark corners do not like Radar Alar. Even in the dark season should be paid to enough light. The plant needs about 1500 lux.

If the leaves are unique, the ray artery also gets by with less light. Variegated varieties often even need 1700 lux. Commercially available plant soil can serve as a substrate. Who wants to increase the permeability in the pot, can add rocks such as perlite or other plant granules. Warmth also loves the tropical genus. Below 10 degrees Celsius, the room temperature should not drop, then the plant reacts with release. Above 20 degrees Celsius are only beneficial for sowing. The plant also likes high humidity.

At constant outside temperatures of around 15 degrees Celsius, the radar artery can also be released outdoors. However, a sheltered location is important here.

Planting and propagating

Radiation Aralyzer can be planted by seeds from the stone fruit. However, as the plant hardly flowers in this country, it is numerous in container goods commercially available. Nevertheless, seeds are also available. If you want to plant yourself, you can plant them in small pots in February or July. Here, coconut soil is suitable for cultivation. Important here is a soil temperature of about 25 degrees Celsius. The Radiation Aralyzer is a dark germ, so the seeds must be covered with a layer of soil. Then the pot must be kept moist until the plant expels. This can put the patience of the gardener to the test - it may take several months to see the first leaves.

A repotting in a larger pot is only advisable if the aralia has formed a branched root system. Propagation by seeds is also not widespread due to the low probability of flowering. Instead, cuttings can be used. But this is also considered difficult because the cuttings rarely root. Here you can either use stem cuttings (in early spring), head cuttings or leaf cuttings. Trunk cuttings can be brought to roots in a tinfoil wrapped water glass. Head cuttings have the best chances in a peat-sand mixture and leaf cuttings in potting soil. The clever gardener uses root aids, ensures a warm and humid climate and plenty of light. After a few weeks, the first roots can show themselves here.

Watering and Fertilizing

Since the ray aralia comes from the tropics, these conditions must also be imitated here in Germany. Therefore, it is important that it has the Schefflera moist. During the growing season from April to September, moderate amounts of water should be given again and again. However, avoid standing water. The Schefflera reacts to water in the coaster with loss of leaves. Watering is necessary when the earth feels dry. A hydrometer is a clever purchase from the Schefflera to best estimate when the roots need new water. For casting, the owner preferably uses rainwater or decalcified water. Also a high humidity says the plant to. Also a spraying of the plant with lukewarm water from time to time is advisable. In the resting phase in winter, it needs much less moisture. Fertilizer can also help the well-being of the radar artery. Between March and September, liquid houseplant fertilizer, fertilizer cones or fertilizer sticks are welcome every two weeks. In winter, fertilizing is enough once a month. Since the plant is evergreen, replenishment of nutrients is needed even in the cold and dark season.

Trimming properly

Radiation artery is one of the fastest growing varieties. Once it has rooted, it can shoot up rapidly. Who wants to curb the size, it must therefore cut. The best time is just before winter and early spring. The clippings are ideal for propagation through cuttings.

Toxicity and Ingredients

As beautiful as the Schefflera looks, unfortunately it is not entirely safe. Because all parts of the plant are poisonous. Leaves and shoots contain oxalate crystals, which can lead to serious consequences both on skin contact and when consumed. These include:


  • Gastrointestinal Problems
  • Diarrhea
  • Vomiting
  • Irritation of the Mucous Membrane
  • Laxity
  • Loss of appetite
  • Caution should be exercised especially in infants and pets. Anyone who does not want to give up the decorative plant should set it out of reach.

Gloves are an ideal choice for the care of the radar artery. Both when cutting and when repotting prevent this skin contact and corresponding reactions.


The Schefflera is not hardy, but belongs to the evergreen plants. With the right hibernation she keeps her leaves. The plant should be placed in cooler areas during the resting phase. Optimal temperatures are between twelve and 16 degrees Celsius. If it gets too cool or too warm, the leaves will be lost quickly. Even pests have an easier game at the wrong temperatures. In the cold season it also requires significantly less water and fertilizer.

Susceptibility to diseases and pests

The greatest attack surface for diseases and pests can be found in the radar artery, when the conditions are not optimal. Too much water causes the leaves to tumble. Also decay is a common consequence. If the room temperatures are not right, lice have an easy time. Wool, shield and aphids infest the Schefflera when it is too warm. Here commercial suppositories help against the vermin, Wollläuse can be dabbed with alcohol and killed. If aphids occur, a cold stream of water helps. If the infestation is very strong, the owner should think about repotting and relocation. But also thunderstorms (thrips) can become dangerous to the ray araly. They can eat like the lice through the plant and eventually kill them. Antidotes here are insecticides and lubricious soap solution. Of course, enemies such as lacewings or predatory mites can help as well.

FAQ - Frequently Asked Questions

Where does the ray aralism originate?

The ray aralia originally comes from Asia. There it is increasingly noticed by large species diversity of the genus. In addition, however, this biodiversity is also found in some regions of Australia.

What is the use of ray aral?

Compared to the original plant, the variant used here is usually kept as a houseplant. Originally, the ray artery was a tree. The reason that the plant is kept as a houseplant, is not due to elaborate breeding, but that the plants used are very young. This reduces the size, but the look is still very handsome, which is why the ornament works so well.

What is the difference between the individual radar anomalies?

The decisive feature in the differentiation of each species is its shape and size the leaves. The Queensland Radiation Aralie is also called, for example, Großblättrige Schefflera. This is characterized by hand-sized leaves, which are divided into five to nine individual sheets. The stature height can also be up to two meters. Slightly smaller is the small-leaved Strahlenaralie. It has a slightly lower stature height and much smaller leaves. The leaf shape is similar to that of the large leaflets.

Another leaf form has the narrow-leaved finger aralia. The leaves are very narrow and equipped with small excesses. The plant is altogether with a maximally 80 cm growth height also clearly smaller than the first two variants. The leaflet fingeraralie grows about half as tall as the narrow-leafed. The leaves are slightly wider, but have a similar shape, because they also have the excesses.

How must the radar artery be cared for?

Especially the casting is a somewhat complicated process, as with most other indoor plants, because the soil should first dry a bit. Then it can be poured, but not to saturation, but only until a reasonably even filling of the earth with water is present. If too much water was poured, it should be poured off after a short time. For fertilizing a houseplant fertilizer is needed. This can be added from time to time, about every fourth pour. If the shoots have grown too long, they can be cut back. This is especially useful before the summer and before the winter.

How can the radar artery be winterized?

The plant actually does not have a real break in growth, as is the case with most plants. Therefore, it continues to grow in winter, but slower because there is less light. If the light supply in the normal location is too low, the plant may have to be illuminated artificially. For this purpose, LED lamps are suitable. Alternatively, the plant can also be placed on a well-lit window. The only important thing is that the room does not get too cold, as the plant otherwise throws off the leaves.

Which temperatures are healthy for the radieal artery?

Especially in winter, attention must be paid to the temperature. Below 15 degrees the temperature should never fall and in some species the limit is even 18 degrees. However, even in the summer too warm a room is harmful. Therefore, a room can be chosen that does not warm up too much and still provides enough light. The temperatures around 20 degrees are well suited.
