Botanical features of the plant

Thunbergia is a herb belonging to the Acanthus family. There are annual and perennial species that are most often grown in open soil. The plant is named after the Swedish naturalist and explorer Karl Peter Thunberg, who studied the flora and fauna of South Japan and Africa with particular interest. Residents of European countries extol another name for tunbergia - Black Suzanne, since in the center of the flower there is a peephole of a dark purple hue.

In one year, the culture can grow 2-8 m in length. The plant is distinguished by a strong root system and branched ground shoots. The leaves have an oval shape, a green tint and small embossed veins, short petioles, oppositely located on the weaving stem.

The diameter of the flower calyx is 4 cm, and the bud itself consists of 5 wide petals, singly located on the peduncles. The color of flowers can be very diverse, ranging from white to red.

After flowering, a fruit is formed - a box in which there are seeds 4 mm in diameter, oblong in shape with a rough brown skin.

Optimal conditions for growth and flowering

Bright lighting is necessary for the normal germination of tunbergia. But in the period from 12 to 3 pm it is better to provide shade so as not to expose the plant to the scorching rays of the sun. The optimum temperature ranges from 21 to 25 degrees.

How to grow a crop from seeds

To properly grow tunbergia from seeds, you need to carefully study the technology of sowing and caring for sprouts.

Sowing terms and technology

Before planting, the seed must be treated with growth stimulants.

Sowing is recommended at the end of winter or in the first month of spring.

Seeding Sequence Algorithm:

  1. Fill the containers with moistened soil mixture enriched with peat, turf and sand. Instead of sand, you can use leafy earth or humus. Mix all three components in equal amounts.
  2. Place the seeds on the surface and sprinkle with a small layer of prepared soil.
  3. Water the planting material carefully.
  4. Cover containers with a special film and place in a lighted place, avoiding direct sunlight.

In the future, it is important to create favorable conditions for germination of tunbergia sprouts and carry out appropriate care.

Germination and care of sprouts

Seedlings should be kept in a room with temperatures ranging from 22 to 24 degrees. Also, make sure that the soil in the container does not dry out and systematically moisten it. Remove the shelter as soon as the first shoots appear. With good care and acceptable conditions, they will appear within a week after disembarkation.

When 2 true leaves are formed, the seedlings need to be thinned out, removing all weak, unadapted sprouts. You can pinch to make the bushes thicker, but do this only when the seedlings reach 12-15 cm. Every week, be sure to fertilize the tunbergia with substances containing nitrogen.

Open ground transplant

Plant tunbergia seedlings in a flower bed after the frost has passed. Better to give the plant the eastern or southern part of the garden. The soil is encouraged to be drained, with a neutral environment, enriched with nutrients.

When planting, observe a distance between the holes of at least 30-45 cm. It is imperative to install a support in the form of a lattice or wire. After planting, water the seedlings well.

The flowering of tunbergia will not keep you waiting long, but will delight you 100 days after pinching.

Flower care

Tunbergia is quite unpretentious in care and grows successfully after a successful planting. But it is still important to provide the culture with proper further care, which includes high-quality watering, fertilization, weeding and protection from diseases and pests.


The plant loves moisture, especially during the flowering period, you need to regularly check the soil and eliminate signs of drying out. With insufficient moisture, tunbergia can be affected by spider mites. Therefore, in case of drought, the plant should be sprayed with a spray bottle. At the end of flowering, it is recommended to reduce watering.


Tunbergia needs feeding during the period of bud formation. For these purposes, it is better to use minerals by adding them to the water intended for irrigation.

Garden bed care: weeding

The soil near the tunbergia should be weeded as necessary and weeds should be removed, which take up a significant percentage of moisture, shade and inhibit the growth and development of flowers. Weeding will also provide oxygen to the roots of the plant.

Diseases and pests: control and prevention

The appearance of mold is a clear sign of waterlogging. Insects such as spider mites, scale insects, whiteflies are dangerous for tunbergia. They can be found on the back of the sheet. In the fight against insidious pests, only special chemicals will help.

What to do after flowering

When the tunbergia has faded, it is necessary to collect the seeds and prepare the plant for the winter period.

Seed collection

At the end of the flowering of tunbergia, in place of the buds, capsules containing seeds will begin to form. It is advisable to collect them before they open. It is advisable to open the torn boxes with your hands over the covered surface, then dry the resulting seeds and send them to cardboard boxes.

Under these conditions, they can be stored for no more than 2 years.

Preparing for the winter period

In autumn, the plant should be disposed of, since it will not be able to survive the frosts. It is best to transplant it into a pot and keep it at home. But before that, cut off the shoots, leaving about 5 buds.

Tunbergia is one of the best plants for decorating a personal plot, balcony, loggia, a separate corner in the room. The main advantages of the culture, thanks to which it is so popular, is its rapid growth and the beauty of flowering.
