Casuarina glauca – prostrate form
An interesting and perhaps underused native ground cover plant the prostrate form of Casuarina glauca (see picture right) is an excellent alternative to many non native plants.
Cascading green foliage and very low growing, in fact ground hugging, it grows well in full sun as long as it is in a well drained environment.
Also known as ‘Cousin It’, this a great plant for tough conditions.
Reaching to .6m when it ‘mounds’ but usually lower, it will trail gracefully over low walls. Individual plants will spread to 3m+ in time. Also known as ‘Cousin It’, ‘Shagpile’ and ‘Kattang Karpet’.
Very useful for planting as cover for stumps and rocks as it will mound over them and cover them up.
As Casuarina glauca has a longish tap root it is a plant that is difficult to transplant once established and being slow growing you will need to find it a ‘permanent home’.
Growing conditions and care
Suited to coastal plantings as well as being useful in rock gardens and as a general ground cover, Casuarina glauca prostrate requires little care once established.
New plantings will require some water, and mulch to retain a little moisture and suppress weed growth is advisable.
Very little maintenance is required other than the removal of any damaged foliage. Judicial pruning can be carried out to maintain size and shape if required. Fertilise with a low phosphate fertiliser, most specialist Australian Native plant fertilisers are suitable for Casuarina glauca prostrate.
