What is Blue Hibiscus?
First, let’s talk about what Blue Hibiscus really is. The truth is, there’s no truly blue hibiscus in nature. What people call “Blue Hibiscus” is usually one of these:
- Alyogyne huegelii: This is an Australian plant that looks a lot like hibiscus. Its flowers are purple-blue.
- Hibiscus syriacus ‘Blue Bird’: This is a type of Rose of Sharon. It has lavender-blue flowers.
- Hibiscus mutabilis ‘Blue Magic’: This is a hibiscus that changes color. It starts white and turns blue-purple as it ages.
For this guide, we’ll focus on Alyogyne huegelii, which is what most people mean when they say “Blue Hibiscus.”
Why Grow Blue Hibiscus?
There are many reasons to grow Blue Hibiscus:
- Beautiful flowers: The big, blue-purple flowers are eye-catching.
- Long blooming season: It can bloom for many months.
- Attracts pollinators: It’s great for butterflies and bees.
- Drought-tolerant: Once established, it doesn’t need much water.
- Fast-growing: It can quickly fill a space in your garden.
How to Grow Blue Hibiscus
Now, let’s look at how to grow Blue Hibiscus:
- Climate: Blue Hibiscus likes warm weather. It grows best in USDA hardiness zones 9-11. If you live somewhere colder, you can grow it in a pot and bring it inside for winter.
- Sun: This plant loves sun. Give it at least 6 hours of direct sunlight each day.
- Soil: It likes well-draining soil. If your soil is heavy clay, mix in some sand or compost to improve drainage.
- Planting: The best time to plant is in spring or fall. Dig a hole twice as wide as the root ball. Place the plant in the hole at the same depth it was in its pot.
- Spacing: If you’re planting more than one, space them 3-5 feet apart. They grow big!
- Watering: Water deeply when you first plant. After that, water once a week if it doesn’t rain.
Caring for Blue Hibiscus
Once your Blue Hibiscus is planted, here’s how to take care of it:
Watering
Once established, Blue Hibiscus is drought-tolerant. Water deeply once a week in dry weather.
Fertilizing
Use a balanced, slow-release fertilizer in spring. Don’t overfeed – too much fertilizer can reduce blooming.
Pruning
Prune in late winter or early spring. Cut back by about one-third to keep the plant bushy.
Mulching
Add a 2-3 inch layer of mulch around the plant. This helps keep moisture in and weeds out.
Winter care
If you live in a cold area, grow your Blue Hibiscus in a pot. Bring it inside when temperatures drop below 50°F (10°C).
Common Problems and Solutions
Like all plants, Blue Hibiscus can have some problems. Here are common issues and how to fix them:
- Yellow leaves: This could mean overwatering or poor drainage. Make sure the soil drains well.
- Few flowers: The plant might not be getting enough sun. Move it to a sunnier spot.
- Pests: Watch for aphids and spider mites. If you see them, spray the plant with water or use insecticidal soap.
- Diseases: Fungal diseases can happen if the plant stays too wet. Improve air circulation and avoid wetting the leaves when watering.

- Focal point: Plant it alone as a stunning focal point.
