Compact bunches of incredibly lovely pale Wedgwood blue starry flowers appear above thin iris-like leaves. This plant was originally grown in a friend's Australian nursery, but grows and flowers unprotected here, and produces a rare and valuable colour in the garden, where it is very long-lived in a well-drained spot.
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
