Great Bougainvillea

The Story

Plant Bio

Bougainvillea spectabilis is a vigorous, scrambling woody vine native to South America, characterized by stout, curved thorns in the leaf axils and pubescent stems. The true flowers are small, tubular, and creamy-white, but they are surrounded by large, papery, brightly colored bracts that provide the primary visual display.

This species is distinguished from other bougainvilleas by its distinctly hairy or pubescent foliage and stems, which feel soft to the touch on new growth. The colorful bracts occur in shades of purple, red, pink, orange, or white and appear in dense clusters throughout the warmer months.

Uses & Benefits:

Provides dense, vibrant vertical cover on trellises, arbors, and walls with its colorful papery bracts.

Functions as a formidable barrier plant or security screen due to its sharp, stout thorns.

Attracts bees, butterflies, and hummingbirds to the small tubular flowers nested within the bracts.

Planting

How to Grow

Select a planting site that receives at least six hours of direct sunlight daily to ensure heavy flowering.
Plant in well-draining, moderately fertile, sandy or loamy soil with a slightly acidic to neutral pH.
Water deeply but infrequently, allowing the soil to dry out completely between waterings to prevent root rot.
Apply a balanced fertilizer sparingly in spring, avoiding high-nitrogen mixes that suppress bloom production.

Pro Tip

Prune immediately after a flowering flush to encourage new blooming wood, and avoid shearing blindly into old, leafless stems which lack the dormant buds needed to regenerate.

Keep It Thriving

Care Guide

Do

Allow the soil to dry out completely between waterings to trigger heavier blooming.
Prune immediately after a flowering cycle to shape the vine and encourage new growth.
Wear thick gloves when handling the plant to protect against sharp, painful thorns.

Don't

Do not overwater or plant in soggy, poorly draining soils, which causes root rot.
Do not apply high-nitrogen fertilizers, which produce lush green leaves instead of colorful bracts.
Do not shear blindly into old, leafless woody stems where new buds cannot break.

When does Great Bougainvillea bloom?

Great Bougainvillea typically blooms in spring through fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Great Bougainvillea need full sun?

Great Bougainvillea does best in full sun (6+ hours).

Is Great Bougainvillea drought tolerant?

Yes — once established (usually after the first full season), Great Bougainvillea handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
