Bougainvillea ‘Key West White’ – A Stunning White Beauty for Your Garden

If you’re looking to add a tropical, flowering plant to your garden, Bougainvillea ‘Key West White’ is a fantastic choice. This gorgeous plant lights up any outdoor space with clusters of creamy white blooms and lush green foliage. It’s a fast-growing vine that brings a bold, bright look to patios, fences, trellises, and sunny garden beds.

What makes ‘Key West White’ special? Unlike other bougainvilleas with loud reds or purples, this variety has soft, clean white bracts that give a cool, elegant feel to your garden. It’s perfect for warm climates, low-maintenance landscapes, and gardeners who want a lot of impact with very little effort.

Let’s explore more about what this plant is, what it needs to thrive, and how you can enjoy it in your own yard.

🌿 What Is Bougainvillea ‘Key West White’?

• Type: Tropical flowering vine
• Color: Bright white bracts (often mistaken for flowers)
• Foliage: Medium green, oval leaves
• Growth Habit: Fast-growing, vining or bushy if pruned
• Mature Size: 15–30 feet tall and wide if left untrained, or smaller with regular pruning
• Sun Needs: Full sun (at least 6 hours per day)
• USDA Zones: Best in zones 9–11, but can be grown in containers anywhere

Even though the white parts look like flowers, they are actually bracts—special leaves that surround the small, true flowers inside. These bracts last a long time and create a beautiful, tropical look that feels like summer all year long.

🌞 Where to Plant It

Bougainvillea needs lots of sunshine. It blooms best when it gets at least 6 hours of direct sunlight per day. The more sun it gets, the more flowers it will produce. If it’s planted in too much shade, you’ll get lots of leaves but very few blooms.

Choose a location with:

• Full sun
• Well-draining soil (it hates soggy roots)
• Plenty of space for spreading or climbing

You can grow it in:

• The ground (ideal for warm areas)
• Large pots (perfect for patios or balconies)
• Hanging baskets (for a trailing effect)
• Against fences, arbors, or trellises

In colder climates, grow it in a large container and bring it indoors when the temperatures drop below 40°F.

💧 Watering Needs

Bougainvillea is drought-tolerant once it’s established. That means it likes to dry out a bit between waterings.

• New plants: Water regularly until they’re established (first 6–8 weeks).
• Established plants: Water deeply but only when the top inch of soil is dry.
• Container plants: Let the soil dry out slightly before watering again.

Tip: Too much water = fewer flowers. Bougainvillea blooms best when it’s slightly stressed (just a little thirsty, not bone dry).

🌱 Soil and Fertilizer

This plant isn’t too picky, but it loves well-draining soil. Sandy or loamy soil works best. If your soil holds water or feels heavy, add compost or coarse sand to loosen it up.

Fertilize during the growing season (spring through early fall). Use a balanced fertilizer (like 10-10-10) or one with a little more phosphorus (like 10-20-10) to help boost blooming.

• Feed once a month during active growing months.
• Don’t overfeed—too much nitrogen = more leaves, fewer flowers.

✂️ Pruning Tips

Pruning is the key to a neat, blooming plant.

• Prune lightly after each blooming cycle to shape the plant and encourage new growth.
• Cut back long, wild vines to keep it full and tidy.
• You can prune heavily in late winter or early spring to shape it before the growing season starts.

Want a bushier look? Prune more often to stop it from climbing and keep it compact. Want a dramatic climber? Train the vines up a wall, fence, or trellis.

🧊 Cold Protection

Bougainvillea ‘Key West White’ loves the heat and doesn’t like cold temperatures. It can survive down to about 30°F, but freezing weather can damage or kill the plant.

If you live in a colder climate:

• Grow it in a container that can be moved indoors for winter.
• Bring it inside when temperatures drop below 40°F.
• Put it near a bright window and reduce watering while it rests in winter.

If planted in the ground and a frost is coming, cover it with a frost blanket or old sheet overnight.

🐝 Pollinators and Pests

The true flowers of bougainvillea are tiny, but they still attract bees, butterflies, and hummingbirds. It’s a great plant to add to your pollinator-friendly garden.

It’s also resistant to most pests, but you might see:

• Aphids
• Mealybugs
• Caterpillars

If pests show up, you can rinse them off with water or use insecticidal soap.

🪴 Container Growing Tips

‘Key West White’ grows well in large pots or planters. Here’s how to do it:

1. Use a big container with drainage holes.
2. Fill with light, well-draining soil (potting mix with sand or perlite).
3. Place it in full sun.
4. Water only when the top inch is dry.
5. Feed monthly during spring and summer.
6. Prune as needed to keep it neat and blooming.

In containers, the plant will stay smaller and is easier to manage than one planted in the ground.

🌼 Why Choose ‘Key West White’?

Here’s why gardeners love it:

• Tropical beauty with clean, elegant white blooms
• Low maintenance once established
• Perfect for hot, dry climates
• Great for containers, fences, and trellises
• Attracts pollinators but resists pests
• Blooms again and again through the warm season
