Protea CAFFRA 'KILIMANDSCHARICA'

Protea CAFFRA 'KILIMANDSCHARICA' - Kilimanjaro common sugarbush, Protea caffra 'Kilimandscharica'.

Protea is a genus of ornamental shrubs and small trees in the Proteaceae family, comprising about 100 species and distributed primarily in Southern Africa.

Plants of this genus are evergreen, with rigid leathery leaves and large showy inflorescences. Proteas are known for their tolerance of hot climates and poor soils, and are used in ornamental floriculture and floristry.

Flowering lasts from spring to summer. The inflorescence is a dense head of tubular flowers surrounded by rigid bracts. Coloration is varied, from pink to cream. The fruit is an achene, often persisting in the inflorescence until the onset of the dry period.

Protea caffra 'Kilimandscharica' is a subspecies with compact growth found on the mountain slopes of Tanzania and Kenya. The shrub height in cultivation is 1-1.5 m (3.3-4.9 ft). The leaves are rigid, lanceolate, glaucous-green, with an entire margin. The shoots are upright and densely leafy.

Flowering begins in mid-spring. The inflorescences are large, up to 10 cm (3.9 in) in diameter, with reddish-pink bracts and a pale cream center. They remain ornamental for several weeks. Seeds mature in late summer.

It is recommended to soak the seeds in warm water for 12 hours. Sowing is carried out in an acidic substrate of peat and sand. Depth is no more than 5 mm (0.2 in). Containers are covered with a transparent dome, ensuring a temperature of 20-24 °C (68-75 °F) and good lighting without direct rays.

Sprouts appear in 30-45 days. In individual cases, germination can take up to 3 months. After the appearance of 2-3 true leaves, pricking out into individual pots is carried out. Watering is limited, with good ventilation.

It is placed in full sun. In shade, ornamental value decreases and growth slows down. Good air circulation must be ensured. It is resistant to dry winds and temperature fluctuations.

The optimal temperature in summer is 22-28 °C (72-82 °F); in winter, keeping at 8-12 °C (46-54 °F) is desirable. Watering is carried out moderately, allowing the substrate to dry out. Waterlogging is not permitted. Good ventilation is required in conditions of high air humidity.

A well-drained substrate with sand, perlite, and gravel is used. The pH is slightly acidic or neutral. Repotting is carried out only by potting on in spring. A drainage layer is mandatory.

Feeding is minimal - no more than once a month during the growth period. Low-phosphorus fertilizers are used. On poor soils, the plant develops better than with excessive nutrients.

Light sanitary pruning is carried out after flowering. Propagation is carried out by seeds. Cuttings are possible, but yield limited results without stimulants.
