Bougainvillea is a genus of thorny ornamental vines, bushes, and small trees native to South America. It’s famous for its vibrant paper-like bracts (often mistaken for petals) in colors like magenta, purple, red, orange, pink, and white.
# # # Quick facts
* **Family:** Nyctaginaceae (four o’clock family)
* **Common uses:** Garden walls, pergolas, fences, hanging baskets, bonsai
* **Climate:** Thrives in warm tropical and subtropical regions
* **Sunlight:** Full sun is essential for heavy flowering
* **Water:** Drought-tolerant once established; overwatering reduces blooms
# # # Why the colors look so bright
The true flowers are actually tiny white centers. The colorful “petals” are modified leaves called **bracts**.
# # # Care tips
* Give at least 6 hours of direct sunlight daily
* Let soil dry slightly between watering
* Prune after flowering to shape and encourage new blooms
* Avoid excessive nitrogen fertilizer, which promotes leaves over flowers
# # # Popular species
* *Bougainvillea glabra* — compact and commonly cultivated
* *Bougainvillea spectabilis* — vigorous climber with larger leaves
* Hybrid varieties — bred for color and growth habit diversity
# # # Interesting note
In many warm countries, bougainvillea is used as a natural privacy screen because of its dense thorny branches and rapid growth.
