Agapanthus

Agapanthus are a hardy and versatile perennial clumping plant that can be used in pots or in the ground to define borders, along driveways, on retaining walls or mass planted under trees.

They are not overly fussy in regards to the soil they are grown in and will tolerate full sun to part shade or even full shade, but will not flower in the full shade.

Agapanthus have dark green fleshy strap like leaves and have white or a bluey/purple colour flower, although the variety “Queen Mum” has a stunning two toned blue and white flower.

Queen Mum is a larger growing variety – up to 1.5m. The regular blue or white plants grow to about 1m.

There are also dwarf varieties such as “Peter Pan” which is blue in colour and “Snowball” which is white in colour. These only grow to around 30cm high.

Apply a liquid feed regularly over the warmer months or a slow release fertiliser at the start of Spring to promote a long flowering period. Dead head flowers as they die off.

Plant Growing Tips

Where to Grow

Agapanthus (*Agapanthus praecox*) thrives in full sun to partial shade. For the best blooms, choose a location that receives at least 4-6 hours of sunlight daily. Agapanthus is ideal for garden beds, borders, or as a feature plant along pathways. It also grows well in containers. Ensure the planting site has well-draining soil, as Agapanthus can tolerate dry conditions but does not thrive in soggy soils.

Climate

Agapanthus prefers a warm, temperate climate and grows best in temperatures between 15°C and 25°C. It is hardy and can tolerate light frost, making it suitable for many Australian gardens. Agapanthus produces clusters of blue or white flowers in late spring and summer, adding height and color to the garden.

Soil Type

Plant Agapanthus in well-draining soil. It adapts well to a range of soil types, including sandy or loamy soils, and can even tolerate poorer soils once established. The ideal pH is slightly acidic to neutral (6.0-7.0). Adding organic matter, such as compost, can improve soil quality and encourage stronger growth.

Fertilizer

Feed Agapanthus with a balanced, slow-release fertiliser in early spring to support healthy growth and flower production. A second application in mid-summer can help sustain blooming. Organic options, such as compost or seaweed extract, are also beneficial and help maintain soil fertility.
