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.

-
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.
