Description How to Grow Delivery

Broad, glaucous-blue, evergreen leaves cascade from dense clumps. Although Dianella revoluta ‘Blue Stream’ is actually a rhizomatous perennial, it looks and is used just like an ornamental grass. Drought tolerant once established, it is fantastic planted in groups in a gravel garden where its steely-blue leaves catch the sun, providing a contrast in texture and colour to mound-forming plants. It also looks wonderful anywhere that shows off its fountain-like habit, such as a container or raised bed. Height: 70cm (27in). Spread: 50cm (20in).

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.
