Strelitziaceae

Strelitzia is a genus of spectacular perennial plants belonging to the Strelitziaceae family. In agriculture and horticulture, this crop is valued primarily as a highly profitable cut flower product, widely sought after in the floral industry for its unique shape, which resembles the head of a bird of paradise.

The crop originates from South Africa. On a commercial scale, Strelitzia is cultivated in countries with tropical and subtropical climates, such as Kenya, Ethiopia, Colombia, and Israel, as well as in greenhouse facilities across Europe. The plant thrives in well-lit areas but requires protection from direct midday sun in hotter regions.

Botanically, these are large herbaceous perennials with robust root systems and rigid, leathery leaves on long petioles. The inflorescences have high density and stiff bracts, ensuring exceptional vase life for cut flowers, which can last up to three weeks if proper post-harvest handling is maintained.

Cultivation technology requires fertile, well-drained soils with a neutral or slightly acidic pH. The plant is sensitive to waterlogging, making quality drainage critical. The optimal temperature range for active growth is 18–25 degrees Celsius, while the winter dormant period requires a drop in temperature to facilitate flower bud initiation.

Key threats to productivity include susceptibility to root rot, powdery mildew, and sap-sucking pests such as spider mites, scale insects, and mealybugs.

• Regular greenhouse ventilation.
• Strict control of substrate moisture levels.
• Application of high-quality fungicides and insecticides.
• Adherence to quarantine protocols for imported planting material.
