Siderasis: Home Care, Replanting And Propagation

A genus such as Siderasis belonging to the Commelinaceae family has only one representative, namely Siderasis fuscata. In nature it is found in the forests of the eastern part of Brazil.

This herbaceous perennial can reach a height of 30-40 centimeters. It has a very short stem and a dense leaf rosette. The leaves are quite large and very fleshy.

The simple leaves are elliptical in shape, about 10 centimeters wide and 20 centimeters long. The glossy front side of the leaves is colored dark green and has a silvery, pale green longitudinal stripe right in the center. The underside is colored greenish-purple.

Small flowers (about 2.5 centimeters in diameter) are colored purplish-lilac and have white stamens.

Also, the flowers, which have 3 petals, are gathered in not very large apex inflorescences-curls. The florets are attached to thick, not long (3-4 centimeters) flower stalks. The plant blooms in May-October.

Siderasis is particularly decorative because of its spectacular pubescence. Almost all parts of the flower are covered with a dense layer of short purple hairs.

This is the reason the plant got its second name, "bear ears".

Care for Siderasis at home

This flower is very rarely seen in one's apartment, also not often seen in flower stores. Siderasis is a very exotic plant, and its happy owners must learn how to properly care for it.


Diffused light is needed, and the light should be at 2500-2700 lux. It grows and develops quite well in the penumbra, but also excels in artificial light and can then do without sunlight at all.

For this plant it is best to choose a window sill located in the northern part of the room. If it has to be placed in the southern part, however, it is recommended to remove the siderasis away from the window opening.

Temperature regime

In the warm season, it feels good at moderate temperatures (22-25 degrees). With the onset of winter, you can move the flower to a cool place (14 to 16 degrees). However, the temperature should not drop below 14 degrees, because the delicate foliage will freeze.

How to water

Pouring is done as the substrate dries up. Make sure to use soft, standing water. The liquid should never get on the leaves. Experienced florists advise watering through a tray. To do this, you need to pour water into a wide tray and put the pot.

After a while, the remaining liquid must be poured out. Mature plants should especially be watered in this way.

Do not allow water to stand still in the soil because the plant will begin to rot. Also, drying out the ground can be fatal because weak roots do not store moisture in reserve and as a result the flower quickly dries up.


High air humidity of not less than 70 percent is necessary.

However, spraying the foliage is not acceptable. To make the humidity high, you can put a little clay pebbles in the tray and pour water in. Also in the immediate vicinity of the siderasis can be put an open vessel filled with water. However, the best way to grow it are terrariums or florariums. This is where the flower will feel its best.

Earth mixture

Made sure the soil is loose and nutrient-dense. You can make the earth mixture yourself by mixing mulch and leaf soil and coarse sand in a 1:2:1 ratio. Do not forget about a good drainage layer, which will help avoid overflow.


Fertilizing is required only during the active growth of the plant 2 times a month. Complex mineral fertilizers for ornamental foliage plants are used for this purpose.

Fertilize less often in the autumn and not in the winter.

Transplanting Ciderasis

Regular transplants are not required as the plant grows quite slowly. As a rule of thumb, this procedure is not done until the roots no longer fit in the pot. For transplanting, take a flower pot slightly wider than the previous one, but it should be low.


No need.

Raising Siderasis

As a rule, it is multiplied by division. To do this, the rhizome is carefully cut into pieces during transplanting. It is extremely difficult to grow from seed, and seedlings often die. Cuttings are also not suitable for propagation.

Diseases and pests

Most often the spider mite settles on the plant.

This pest is very difficult to get rid of because the leaves should not be moistened. However, there is a fairly effective folk method. Siderasis should be tightly covered with a polyethylene bag, and inside it to place balls of absorbent cotton soaked in dichlorvos (do not put them on the leaves or the ground).

Practically not prone to diseases, but, if not cared for properly, it can lead to loss of ornamentality, and also to the death of the plant. So, you should not allow not overwatering or overdrying of the substrate.

Also if there will be low humidity, the tips of the leaves will start to dry out. The plant will lose its decorativeness for a long time because new foliage grows very slowly.
