Orthrosanthus polystachyus – Morning Flag Iris

Botanical Name: Orthrosanthus polystachyus

Common Name: Morning Iris, Morning Flag

Average Height (cm): 60

Average Width (cm): 23

Description:

A clump-forming perennial with slender green leaves and tall stems of delicate blue, star-shaped flowers in spring. It differs to Orthrosanthus multiflorus in how the flowers are displayed on tall stems with multiple stacks of flowers along the stems. It will be slower to flower than O. multiflorus but it is oh so worth the wait! The flowers are a stunning and unusual colour, quite difficult to capture in a photo. It is a real statement plant when in flower, and when not it blends beautifully with it’s wide grass like leaves.

Garden Design Uses:

A stunning replacement for exotic bulbs and Iris in Australian gardens. It will blend well with grasses but in late spring to early summer is stunning in bloom. It contrasts well with hardscaping, blends beautifully with native grasses and makes a useful contrast to rounded and compact shrub shapes.

Care:

Prefers full sun to partial shade and benefits from summer watering. Drought-tolerant once established. Remove spent flower spikes to maintain neat appearance – this also helps it to flower next year as it can get too fatigued if you leave all the seeds in tact to develop on the plant.
