Blue & White Agapanthus – Hardy, Stunning & Easy to Grow

Whether you’re drawn to the deep, rich tones of Blue Agapanthus or the crisp elegance of White Agapanthus, both varieties bring structure, colour and reliability to the garden. These plants look just as good when not in bloom, with their neat, evergreen leaves, and then explode into globe-like flower heads in summer. Perfect for borders, driveways, or as a feature in large pots, they suit everything from formal gardens to relaxed coastal yards.

Agapanthus Size & Height

Agapanthus grow around 60–80 cm tall in leaf, with flower stems reaching 1–1.5 m when in bloom. This gives them enough height to add drama without blocking views, and makes them excellent for low-maintenance hedging or as a repeating accent along pathways.

Low Effort, Big Reward

One of the biggest reasons both blue and white agapanthus are so popular in Australia is how little care they need. Plant them in full sun, give them well-drained soil, and water them while they establish. After that, they’ll cope with dry spells, poor soils, coastal winds and the general “set and forget” approach many of us want in a garden. A light feed in spring will encourage lush foliage and more flowers, but even without it they’ll keep coming back year after year.

Flowering & Seasonal Interest

Blue agapanthus flowers bring bold, deep blue tones from late spring into summer, while white agapanthus offers bright, snow-white blooms that work beautifully in moon gardens or mixed colour schemes. Both look fantastic en masse, and their tidy foliage ensures the bed still looks green and structured once the blooms are done.

How to Use Them in Your Garden

• Create a white agapanthus hedge along a driveway for a clean, formal look.
• Mix blue and white agapanthus for a soft coastal palette.
• Plant large clumps of one colour for dramatic summer impact.
• Grow in oversized pots near the pool or patio for easy seasonal colour.
