Description
Striking Variegated Flax Lily Dianella ‘Silver Streak’ is a beautiful Australian native plant with distinctive silver, white and green striped foliage. Its compact clumping habit and attractive colouring make it an excellent choice for borders, mass planting, pathways, pots and contemporary landscape designs. Unlike plain green Dianella varieties, ‘Silver Streak’ has particularly eye-catching variegated foliage. The long, strap-like leaves are marked with silvery-white and green striping, creating a bright, architectural effect in the garden. Plants form neat clumps reaching approximately 50–60cm high and 50–60cm wide, making this variety useful where a smaller native plant is required. Attractive Year-Round Foliage The foliage is the main feature of Dianella ‘Silver Streak’. Its narrow leaves create a soft but structured appearance, while the silver and white markings help brighten darker garden areas. The clumping growth habit also makes it useful for planting along pathways, garden edges and larger feature plants. Several plants planted together can create a particularly attractive flowing effect. During the warmer months, flowering stems rise above the foliage and produce delicate blue to violet-blue flowers. These provide a lovely contrast against the silver-green leaves and add seasonal interest to the garden. Flowers may be followed by attractive blue to blue-purple berries, extending the ornamental display. Versatile Australian Native Dianella ‘Silver Streak’ is a versatile choice for Australian gardens and works particularly well in modern, native and low-maintenance landscapes. Use it as an edging plant along paths, as a foreground plant beneath larger shrubs and trees, or in groups to create a stronger visual impact. Its compact size also makes it suitable for containers and courtyard gardens. Growing Dianella ‘Silver Streak’ Plant in full sun to part shade. A position with good light will generally produce strong foliage colour, while some afternoon protection can be useful in particularly hot locations. Dianella is adaptable to a range of well-drained soils and is relatively low maintenance once established. Water regularly while young to help develop a strong root system. Established plants can tolerate periods of dry weather, although occasional deep watering during prolonged heat and drought will help maintain their appearance. Remove older or damaged foliage when necessary to keep the plant looking fresh. After flowering, spent flower stems can also be removed if a tidier appearance is preferred. Avoid consistently waterlogged soil, particularly in heavy clay. Great for Small Garden Spaces With its manageable size and distinctive foliage, Dianella ‘Silver Streak’ is a particularly useful plant for gardeners looking for an Australian native that doesn't overwhelm a garden bed. Its silver-striped leaves provide colour and texture even when the plant isn't flowering, while the blue flowers add an extra seasonal feature.
