Crinodendron

The genus Crinodendron (Crinodendron), also known as Tricuspidaria (Tricuspidaria), consists of two species. Large shrubs and trees, evergreen and fairly stable, grow up to 5 m in height (in the conditions of natural growth up to 9 m). These are very lush plants with spreading branches. They are very much appreciated for their beautiful dark foliage and abundant flowering. Glossy leathery simple dark green leaves with a slightly toothed edge are arranged alternately or opposite. The flowers are solitary or bloom in pairs, drooping, with a long pedicel. Often, the buds are kept for a whole season on the plant does not open. The corolla is tubular-bell-shaped, sometimes pitcher-shaped (shaped like a pitcher). Crinodendron Hooker (Crinodendron hookerianum), or Tricuspidaria lanceolate (Tricuspidaria lanceolate), is a shrub or tree. Large branches grow upwards. The leaf plate 5-10 cm wide is attached to a short thin petiole; the leaves are elliptical or lanceolate, dark green in color, with a glossy upper side, slightly pubescent lower. In the period from April to June, hanging flowers like lanterns bloom, their corolla is colored in colors from scarlet to bright crimson and purple. Crinodendron patagua (C. patagua), or tricuspidaria drooping (T. dependens), usually grows in the form of a large bush, but can have the shape of a tree. The branches point upward. The width of slightly leathery dark green leaves is 3-7 cm, the shape is elliptical to oblong. In summer, white hanging bell-shaped flowers bloom, which open more than in Hooker's crinodendron.

Cultivation

Plants of the genus Crinodendron are grown in the open ground in the garden (in mild climates) or in pots, which in cold climates are brought into the house for the winter. They are planted permanently in spring in a fairly moist, slightly acidic, fertile soil, but they provide good drainage. When planting, it is recommended to apply organic fertilizers (5-7 kg /m2). When preparing the soil for growing in a pot, 2/3 peat and 1/3 peat are used sod land, it is filled with a complex fertilizer and iron chelates at the rate of 20 g per bucket. It is strictly forbidden to use lime fertilizers. In the period from May to August, a complex mineral fertilizer in the amount of 10-20 g per bucket is added to the water for irrigation every 20-30 days. Pruning is limited only to removing dry and damaged branches.

Location

Plants of the genus Crinodendron prefer a semi-shaded place, well protected from cold winds.

Temperature

These plants are thermophilic, although they can tolerate a drop in temperature to -10 °C, but they are afraid of prolonged frosts.

Watering

Water generously and abundantly to keep the soil moist, but without stagnating water. Crinodendron Patagua can tolerate a short drought.

Transplant

Transplanted once every 1-2 years in the spring, in a new, several sizes larger than the old, pot. When the pot is already difficult to manipulate, you can limit yourself to replacing the surface layer of the earth.

Reproduction

In July-August, semi-lignified cuttings are taken and placed for root formation in a mixture of sand and peat (1:1). After the formation of roots, new plants are planted singly in pots and kept for the winter in a closed and well-lit room with a temperature of approximately 16 °C. In the spring, they are taken out into the fresh air, but they are planted in a permanent place in the ground only for the next year.

Diseases

If the ground is waterlogged and water stagnates in it, root rot occurs, caused by various fungi, which can completely destroy the plant. With an increased pH (soil acidity), chlorosis begins, which ultimately leads to a delay in plant growth. Use suitable soil and feed it with iron chelates.

Acquisition

Plants of the genus Crinodendron can be found in horticultural centers and specialized nurseries offering an expanded range of crops. Choose plants that are not too overgrown, they are easier to plant in the ground, and they are easier to transfer. Make sure that the seedlings are healthy when buying.
