Originally from South America, the vibrant bougainvillea thrives not only in coastal areas and the South but also on your balcony, bringing a touch of tropical allure to your home. This climbing beauty, also known as bougainvillea or bougainvillea, can be a striking addition in pots. Learn about its flowering patterns and how to guide it to climb a support.

Bougainvillea Overview: Bougainvillea, a climbing plant, offers an enchanting spectacle with its flamboyant flowers. The name was bestowed in honor of the French explorer Louis Antoine de Bougainville, who discovered this plant in Brazil in 1768. Its evergreen nature presents a riot of colors, ranging from pink, fuchsia, magenta, purple to red and orange.

Varieties and Species: The genus Bougainvillea comprises 18 species and numerous varieties. Some notable ones include:

  1. Bougainvillea glabra: Luxuriant, reaching up to 10 meters, with bright leaves.
  2. Bougainvillea aurantiaca: Thrives in hot temperatures, showcasing ocher yellow leaves.
  3. Bougainvillea x buttiana: Hybrid with varied colors resulting from cross-breeding.
  4. Bougainvillea spectabilis: Brazilian origin, featuring intense pink bracts.
  5. Bougainvillea speciosa: Brazilian species with heart-shaped, pink-to-fuchsia bracts.
  6. Bougainvillea refulgens: Brazilian origin, displaying pendulous panicles in purplish tones.

Cultivation and Care:

  1. When to Plant: Choose spring for operations like seeding, transplanting, or cutting, as the climate supports bougainvillea’s life cycle.
  2. Location and Temperature: Bougainvillea thrives in full sun, adapting well to temperatures above 40°C. In winter, shield it from temperatures below 10°C and cold winds.
  3. Soil and Fertilization: Opt for well-drained, low-limestone soil. Use a flowering plant fertilizer rich in nitrogen, phosphorus, potassium, and microelements every two to three weeks.
  4. Watering: While bougainvillea tolerates drought, provide periodic watering, avoiding stagnation that may lead to root rot.
  5. Flowering: Expose the plant to at least 5 hours of sunlight daily to witness vibrant summer flowering.
  6. Pruning: Prune at the end of winter to thin out foliage, remove dry branches, and encourage new growth.
  7. Diseases and Parasites: Hardy but susceptible to aphids and scale insects. Use a broad-spectrum insecticide to counter insect attacks.
  8. Winter Care: Protect bougainvillea from cold by sheltering it from wind and insulating the pot with polystyrene. Minimize watering and move potted bougainvillea indoors in extremely cold climates.

Expert Tips: Stefano Pagano, a seasoned gardener, recommends:

  • Place bougainvillea in full sun for rapid growth.
  • Maintain soil at a slightly acidic pH, using specific soils for acidophilic plants.
  • Generously fertilize from May onward with ready-made liquid fertilizers, diluted every 15 days.
