1. Basic Identification

Common Name: White Bougainvillea / Paper Flower
Botanical Name: Bougainvillea glabra 'Alba'
Arabic Name: جهنمي
Plant Color: White
Country of Origin: Spain (Cultivated / Native to Brazil)

2. Taxonomy & Classification

Kingdom: Plantae
Order: Caryophyllales
Family: Nyctaginaceae
Genus: Bougainvillea
Species: Bougainvillea glabra

3. Origin & Distribution

Originally native to Brazil and South America, the Bougainvillea glabra is now widely distributed across Mediterranean climates, particularly in Spain, Italy, and Greece, as well as tropical and subtropical regions globally.

4. Visual Characteristics

This evergreen woody vine features lush green, ovate leaves and sharp thorns. The 'Alba' variety is distinguished by its stunning, paper-like white bracts that surround tiny, inconspicuous creamy-white flowers. Its growth habit is scrambling and climbing.

5. Size & Dimensions

In outdoor environments, it can reach heights of 3 to 10 meters (10 to 30 feet) if given a structure to climb. When grown in pots or kept as a shrub, it is typically maintained at 1 to 2 meters in height.

6. Light Requirements

Thrives in full sun. To produce the best white bract displays, it requires at least 6 to 8 hours of direct sunlight daily. It will survive in partial shade but flowering will be significantly reduced.

7. Watering Needs

Bougainvilleas are drought-tolerant once established. Water deeply when the top 2-3 inches of soil feel dry. Overwatering should be strictly avoided as it can lead to root rot and fewer blooms.

8. Soil & Potting

Requires well-draining, gritty soil. A mix of peat moss, perlite, and sand is ideal. It prefers a slightly acidic soil pH between 5.5 and 6.5. It performs well in pots but requires excellent drainage holes.

9. Temperature & Humidity

Thrives in hot, dry, or humid conditions. It is frost-sensitive and performs best in temperatures above 15°C (60°F). It can tolerate high heat and is well-suited for arid rooftop gardens and sunny patios.

10. Fertilization

Apply a high-phosphate or "bloom booster" fertilizer every 4 weeks during the spring and summer growing season to encourage flowering. Avoid high-nitrogen fertilizers which promote foliage growth at the expense of blooms.

11. Maintenance & Care Level

Low maintenance but requires regular pruning. Pruning after each flowering cycle helps maintain its shape and encourages new growth for the next bloom cycle. Be cautious of the sharp thorns when handling.

12. Growth & Propagation

This is a fast-growing plant. Propagation is most successful via semi-hardwood cuttings or tip cuttings taken in early summer and kept in warm, humid conditions until rooted.

13. Common Problems

Susceptible to aphids, spider mites, and whiteflies. Overwatering can lead to leaf drop and root rot. Lack of sufficient sunlight is the most common reason for a failure to produce white bracts.

14. Benefits & Uses

Primarily used as an ornamental plant for landscaping, privacy screens, and trellises. It is excellent for erosion control on slopes and is a popular choice for Mediterranean-style home décor and entrance styling.

15. Toxicity & Safety

The sap of the Bougainvillea can cause mild skin irritation or dermatitis in sensitive individuals. The thorns are sharp and can cause physical injury. Ingestion of the plant may cause mild gastrointestinal upset in humans and pets.
