Pimelea Ferruginea | Growing + Care Guide Australia

Growing Australian native plants is always a great idea, as they almost guarantee success, being accustomed to our climate and general environment. Few are as striking as the Pimelea ferruginea, or pink rice flower.

This fantastic flowering plant is a great way to add an almost year-round pop of pink into your garden. With large flower clusters and dense growth habits, this species is perfectly suited for coastal gardens, rockeries, as a border plant or even in pots around your garden.

Here is everything you need to know to grow, care for and propagate Pimelea ferruginea.

Genus: Pimelea
Species: P. ferruginea

How to Grow Pimelea ferruginea

While this species struggles to grow in tropical and sub-tropical climates, it can be found happily growing along the entire South West coast of Australia. Belonging to the Thymelaeaceae family, this species is a smaller growing shrug with a long-flowering dense appearance.

Its bloom clusters often range in colour from deep to light pink—these contrast magnificently against the dense, dark green foliage. Other common names for this species include the rosy rice flower and rice flower pink solitaire.

Pimelea ferruginea prefers a coastal climate, but they have been known to succeed inland. What gives the Pimelea its beauty is the way the flowers cluster together at the end of the stem.

The individual flowers themselves are quite small but because they cluster together much like the Hydrangea

While it only grows about 1 metre tall, it can grow as much as 2 metres wide, so make sure you give it sufficient space to grow, especially if planning on growing your pink pimelea in a pot. 

As with most flowering plants, it requires a lot of good sunlight. However, while it may prefer full-sun conditions, it is possible to grow pink rice flowers in the partial shade. Though, you may have slightly fewer flowers. 

This adaptable species can grow in almost any kind of soil. Naturally growing in rocky landscapes and many coastal sand dunes, if you’re planning on growing pink rice flowers in a pot, it’s best to choose a sandy or loam soil medium.

The most important factor will be to guarantee well-draining soil. Pimeleas suffer in overly moist conditions.

How to Propagate Pink Pimelea

Unfortunately, propagation from seed is incredibly unreliable with this species.

Luckily, though, you can freely propagate young plants from a stem cutting. These can often be readily available after pruning.

After taking a cutting, you can simply dip the cut end of the plant into a rooting hormone, then plant directly into the soil, allowing it to root. Be sure to give your cutting plenty of moisture and sunlight in the first few weeks. 

Pimelea ferruginea Care

Once established, this plant requires very little additional care. Be sure to allow water to drain fully between watering to avoid any issues. 

You can support your pink rice flower twice a year with a little bit of fertiliser. A good native fertiliser should be used during the winter, while a softer, mineral fertiliser can be added during the spring. 

Pruning is not always necessary but can help you to curb unsightly spent flowers and promote further dense growth. Be sure to use a sterilized pair of shears to avoid the spread of any disease or fungus. 

Pruning should be done after the first major flowering season to encourage continuous growth. Pinching back new growth will also help to maintain your shrub’s fullness.
