|Difficulty of care|
Winged Tunbergia belongs to climbing plants. Its pubescent stems grow up to 3 m in length. Leaves are opposite, pubescent from below, ovate or triangular-ovate in shape 2.5–7.5 cm long with small notches at the edges. At the base, the shape of the leaves resembles a heart. Petioles are approximately equal in length to leaf blades.
The flowers of this species are axillary, with a diameter of up to 4 cm, attached to the stems with long pedicels. The color of the corolla border is cream or yellow-brown with black edges.
With this type of vine, with proper care, many single flowers grow. They are united by a characteristic black eye in the center, and the color scheme is quite diverse. Common colors: white, yellow, brown, cream and orange. There are several varieties of winged Tunbergia: Alba, Auraotiaca, Bakeri, Doddsii, Frieri and Lutea.
The plant actively blooms in June. To prolong the process, wilted flowers must be removed in a timely manner. This species is common among lovers due to its decorative properties. It can be grown like an ampelous plant, but it grows well on supports, to which it must be tied.
2.1 Propagation, growing from seeds
Plant seeds are sown in early spring. At an air temperature of about 20 ° C, germination will occur within 1 - 1.5 months. Vegetative propagation is carried out using half-ripened stem cuttings in spring and summer. Cuttings 8 to 10 cm long are separated with a sharp sterile instrument and rooted in a mixture of wet peat and sand, using growth hormones.
2.2.Tunbergia at home
Pinch fading flowers to extend flowering time. Thin stems of the plant provide support, which they easily braid. The apical buds are regularly nipped to form lateral shoots. To maintain a neat shape, stems that are too long are cut off. If possible, place the plants outside during the warmer months.
2.3 Growing conditions - temperature
Suitable year-round warm content at ordinary room temperature in the range of 18 - 24 ° C. In the fall it is advisable to take the plant to a cool place where it will spend a period of rest. In the cold season, do not expose plants to temperatures below 10 ° C.
2.4. Soil for tunbergia
Soil should easily pass moisture and be sufficiently nutritious. A mixture of peat, leaf humus, well-rotted manure with the addition of drainage materials is suitable. The soil must have a neutral or near neutral pH.
2.6 Pests and diseases
With insufficient lighting, flowering will be less plentiful or not at all. Prolonged exposure to direct sunlight during the daytime leads to burns on the leaves. Fungal diseases occur in poorly ventilated areas. Plants rot with insufficient drainage or excessive watering.
Spider mites, whiteflies, aphids, scale insects.
(Thunbergia Alata) representative of the Acanthus family (Acanthaceae). In its natural environment, South and Southeast Africa - this long, strong plant is a climber (vine) and grows up to 3 meters in length. The winged tunbergia grows rapidly, but in our climate reaches a length of only 100-150 cm. The stems are slender, sparsely branched, covered with diametrically opposed paired green leaves in the shape of a heart. The upper side of the leaves is shiny. In June, ornamental flowers appear in the axils of the leaves, consisting of five petals in the form of a crown, forming a slightly swollen tube in the lower part. The outer part of the petals is mostly orange (there are yellow and white flowers), while the inside of the tube is dark (almost black).
The latest developments of the breeders were presented to the gardeners of Tunberg with flowers of cream color and even without dark spots. Thunbergia blooms until October. During intense heat, flowering decreases, but with decreasing temperature, flowering again becomes more plentiful.
Winged tunbergia not hardy, and already the first, severe autumn frosts can cause its death. Nonetheless, tunbergia flower can winter indoors. In this case, next year the plant will begin to bloom earlier than usual flowering time. To do this, before the first autumn frosts, the flowers are transferred to a bright room and kept throughout the winter at a temperature of about 10 ºC. During this period, flowers tunbergia may lose leaves and go to rest.
In the spring, before putting flowers on the balcony, they are transplanted into nutrient soil and the stems are cut. Then the plant is transferred to a room with a temperature of 15-18 ° C, which leads to the resumption of growth and the formation of young shoots. On the eve of May (June), when the air temperature stabilizes at 10-15 ° C, the plant is taken out to the balcony, terrace or garden.
The soilfor good growth and development of the plant should be fertile, with a light alkaline environment, moderately moist and drained. An excellent earthen mixture is compost or a special substrate for flowering plants.
Location. Winged Tunbergia on the balcony requires shelter from strong winds (gusts can damage delicate leaves and flowers). The plant can grow not only in full sun, where it blooms profusely, but in partial shade, where it will bloom less. In spring and autumn, it is best to place a liana on the south side of the terrace.
Watering. Tunbergia winged constantly requires a slightly moist substrate. This is especially important during the flowering period, because due to lack of moisture, the plant withers, and all blooming flowers wilt. If this happens, then no watering can lift the plant. Therefore, the flower is abundantly watered, on especially hot days, even twice: early in the morning and late in the evening. Tunbergia require regular top dressing, which should be carried out immediately before the development of the first buds. It is better to use fertilizers for flowering plants.
