Barbara Karst Bougainvillea

Bougainvillea ‘Barbara Karst’

Barbara Karst Bougainvillea is one of the most popular bougainvillea varieties, celebrated for its brilliant, magenta-red bracts that blanket the plant in vibrant color nearly year-round in warm climates. This vigorous, fast-growing vine can be trained to climb walls, trellises, or arbors, or grown as a sprawling shrub. Its lush green foliage and show-stopping color make it a favorite for adding dramatic tropical flair to gardens and landscapes.

Growing Bougainvillea ‘Barbara Karst’

• Light: Full sun is essential; at least 6 hours daily for the best flowering.

• Soil: Prefers well-draining soil; sandy or loamy types are ideal.

• Water: Low water needs once established; allow soil to dry between deep waterings.

• Fertilizer: Feed monthly in spring and summer with a low-nitrogen, bloom-boosting fertilizer.

• Maintenance: Prune after bloom cycles to control size, encourage branching, and promote heavier flowering.

• Hardiness: USDA zones 9–11; frost-sensitive, but can be overwintered in containers in cooler regions.

• Wildlife: Flowers attract hummingbirds and pollinators.
