The homeland of the bush is considered to be Polynesia. It is a special shrub plant with a height of about 1-1.2 m. The upright shoots are covered with broad-oval leaves with sharp ends 15 cm long and 10 cm wide. The leaf plates have a unique pattern consisting of multicolored spots, stripes and strokes. The leaves are attached to thin petioles, have solid edges and pronounced veins. The main background of the leaf is dark green or purple.

The pattern consists of pink, yellow, white or red, irregularly spaced spots. The intensity of the color of the leaves is directly influenced by the degree of lighting in the room. During flowering, white buds with purple spots form on the tops of the shoots. Flowers form racemose inflorescences, the length of which does not exceed 15 cm. The flowers have a yellow or red calyx. This type has two subspecies: Tricolor and Variegata, which can be distinguished by the shades of the leaf plates. Each petal of a flower has two parallel lines along the axis.

The optimum temperature for Pseuderanthemum carruthersii in summer is 22-25 °C, while in winter the temperature should not drop below 20 °C. The plant is afraid of sudden changes in temperature, cold drafts and hot air from heating appliances. In winter, it is recommended to use a potholder


The plant needs bright, diffused lighting, which allows it to reveal all the beauty of the leaves. The window sill of the western or eastern window will suit him well. In winter, additional lighting with fluorescent lamps may be needed, since the color of the leaves fades in the absence of lighting.


Pseuderanthemum carruthersii needs equally abundant watering in summer and winter without the slightest tolerance for overdrying the earthy coma. Watering is necessary with soft, settled water at room temperature. In autumn and winter, watering is regulated relative to the temperature of the content. There should be no stagnant moisture in the soil, but at the same time, overdrying should not be allowed, as this can lead to the death of the plant. At the same time, it should be borne in mind that frequent, but insufficiently abundant watering can lead to poor results. After watering, the water from the pallet must be drained

For Pseuderanthemum carruthersii, high air humidity is required throughout the year, the plant does not tolerate the slightest drop in humidity below 75%. In summer, regular, abundant spraying is necessary, and in hot weather it is necessary to arrange a warm shower for the plant to prevent pests. It is necessary to regularly clean the leaves from dust without using a sheet polishing agent. This issue becomes critical in winter. To increase humidity, you can use humidifier devices or pallets with expanded clay or moss, complementing this with spraying and water procedures.

Crown formation

Pseuderanthemum carruthersii is a shrub plant that needs to form a lush bush by pinching and pruning. This increases its branchiness and decorative effect. The lateral shoots of the plant are always directed strictly to the top, and in order for the plant to acquire the best shape, it is necessary to carefully bend them down and tie them to the pot with a flexible cord. This pinching should be done annually before transplanting the plant.

If the lower part of the trunk is bare and the plant has lost its decorative effect, the rejuvenation of the bush is carried out – for this, the cuttings obtained by pruning the plants are rooted. Cardinal pruning is not suitable for Pseudo-erantemum.


It is necessary to fertilize the plant during the period of active growth from spring to autumn, once a month, with fertilizer for decorative deciduous plants with a high potassium content, which it needs to maintain the brightness of the color of the leaves. The plant does not tolerate nitrogen. Pseuderanthemum carruthersii responds well to organic fertilizers.


For Pseuderanthemum carruthersii, the soil should be light, loose and nutritious. Soil is suitable for decorative flowering plants, a universal substrate in which it is desirable to add humus, charcoal, perlite. Good drainage is needed not only at the bottom of the pot but also throughout the soil.


The plant must be transplanted annually, combined with pruning. The plant tends to quickly grow the root system, therefore it is permissible to shorten the roots of the plant since it is simply impossible to constantly increase the capacity. When growing especially large specimens, you should try to continue to increase the capacity of the pot.

Usually, propagation with cuttings is done by pruning the plant. The stalk for rooting is cut in front of the bud at an oblique angle, it must be at least 15 cm and have at least 3 nodes. It is rooted in water at a temperature not lower than 25 °C. Roots appear within a couple of weeks. It can be rooted according to the standard scheme – in a mixture of peat and sand, under a film or glass cover. The plant is planted in a pot no more than 13 cm in diameter, and only after the roots of the plant fill the entire pot are transplanted into a larger one. This is done in order to stimulate the plant to bloom. To create a more lush pot, it is permissible to plant 2 or more plants in a pot and pinch them regularly to stimulate branching.

Growing problems

  • The tips of the leaves dry out under excessively dry conditions or exposure to direct sunlight.
  • Brown spots on leaves under excessive light.
  • Falling foliage occurs due to draft, insufficient watering, waterlogging.
  • The foliage turns yellow and dries up if the plant is too hot and dry or the soil is waterlogged.
