Lomandra have the common name of Iron Grass in many cases. The leaves are very tough. I tried to pull a dried leaf from a clump and gave up. Besides I was in danger of cutting my hand.
These are attractive clumping plants. The male and female flowers are borne on separate plants. They look great in groupings of plants rather than one isolated plant. On the other hand they are very attractive growing amongst other plants in a rockery.
Lomandra effusa is the species which occurs on our block. It has leaves to 30cm tall. The flower spike in both the male and female are similar in appearance. The flowers are a pretty creamy white formed along a stem rising from the base of the clump. The common name is Scented Mat Rush. When down on hands and knees the perfume can be detected and it is very pleasant.
