Plant Profile – Spreading Landscape Plants

There are a number of plants that have a reputation for spreading across, and sometimes beyond, the area in which they are planted. This can be a problem if you are unaware of the spreading habit of the plant before you use it. If it is planted in the wrong location it will spread into unwanted areas, will take over other plants and will over run the area causing nothing but headaches.

A plant’s ability to spread is not necessarily a bad thing, it can actually be a real asset in the landscape. Spreading plants can be just what you are looking for in the right circumstances. They can out compete weeds, reduce soil erosion by strengthening and binding soil together and revamp a sloping or rocky area that is difficult to mow or maintain.

I would like to feature 2 spreading landscape plants with rhizomatous growth habit which are ideal for creating fast growing dense ground covers.
Lucia is a low growing form of Dianella caerulea with an amazing ability to spread. It would have to be the fastest and the best spreading Dianella out there. Lucia is ideal for planting in median strips, roadsides, large mass planted areas, along a fence or as a ground cover it excels.

Lucia has multiple rhizome shoots to develop a mat of foliage, this attribute allows it to carpet the ground and recover quickly from any damage. Lucia has unusual deep mulberry colour flowers which are bold and prolific throughout spring. Planted at 4 plants per square metre, it is a low cost, drought tolerant, ground cover option for mass planting.

If you are planning to use Lucia remember the old saying right plant for the right place, you are not going to use Lucia as a garden border amongst other plants, as it will spread into them and eventually out compete them. If you want to use it in a garden design it can be used successfully given enough room to spread without affecting other plants.

Yalba is a newly developed form of Imperata cylindrica commonly called Blady Grass. This is an Australian plant unlike the other well known Imperata cylindrica commonly called Japanese Blood Grass, that is obviously of Japanese origin. Yalba is very fast growing and spreads more rapidly than the common Australian form. It is ideal for areas that need a quick native ground cover, such as median strips, roadsides, slopes and other mass planted areas.

Yalba is only recommended for areas where it can be contained such as median strips or where you require a mono culture planting where it will not interfere with other plantings or spread into any unwanted areas. Yalba has a very strong vigorous habit, so this needs to be an important consideration when specifying or using this plant.

Yalba grows to a uniform height approximately 400mm high making it more compact than the common Australian Imperata cylindrica. Yalba is excellent for erosion control and its deep rhizomes make it drought tough and its vigour helps it out compete weeds. It also develops reddish toned foliage in autumn and winter and green foliage in the warmer months.

Be smart when using these types of plants as when they are used in the correct applications they will certainly do the job for you.
