What Is Blue Flax Lily?

The term "blue flax lily" usually refers to members of the Dianella genus, prized for their year-round beauty and toughness. Their slender, blue-green leaves form dense clumps, while small, starry blue or violet flowers appear above the foliage in spring and summer, followed by vibrant blue or purple berries. Both the flowers and berries add a splash of colour and attract native birds and pollinators into your garden.

How to Grow Blue Flax Lily in New Zealand

One of the key reasons blue flax lily is so popular is its adaptability. It tolerates sun or part shade and thrives in a range of soils, including sandy and clay types. It’s drought-tolerant once established but also copes with wet feet, making it an asset in challenging garden spots such as slopes or rain gardens. Simply plant blue flax lily in well-drained soil, water during long dry spells, and apply mulch to help retain moisture and suppress weeds. Its tidy growth habit means little maintenance is required—remove old leaves occasionally to keep your flax lilies looking lush.

Landscape Uses for Blue Flax Lily

Blue flax lily's lush foliage and compact growth make it a top contender for ground cover, mass plantings along paths, edging, or under low trees. Its roots help stabilise soil, so it’s often used for erosion control on banks and slopes. Pair blue flax lily with other tough, drought-tolerant perennials like Agapanthus 'Peter Pan' (Lily Of The Nile) for a dynamic, low-care planting scheme. For a bolder foliage statement, explore companion varieties such as Dianella 'Little Jess', Dianella Kentlyn, Dianella Goddess, and Dianella 'Revelation'.

Blue Flax Lily Varieties

If you love the classic blue flax lily, discover the range of forms and compact varieties bred for New Zealand gardens. Dianella 'Little Jess' is famously compact and tidy, perfect for smaller spaces or formal edges. Dianella Kentlyn offers robust growth and vibrant colour, while Dianella Goddess is celebrated for its abundant flowering. For modern gardens, the striking foliage of Dianella 'Revelation' brings a touch of the extraordinary.
