Whether you’re a seasoned horticulturalist or a budding enthusiast, acquiring an Illawarra plum tree can bring a touch of the Australian bush to your backyard, along with a bounty of delicious fruit for your kitchen.
Understanding the Illawarra Plum Tree
The Illawarra plum tree is a member of the Podocarpaceae family, which also includes other coniferous plants. However, Podocarpus elatus is a broad-leafed evergreen, often mistaken for a traditional pine due to its needle-like leaves. These leaves are typically 5-15 cm long, dark green on the upper surface, and paler underneath, arranged spirally along the branches. The tree itself can grow to a considerable size, often reaching heights of 10-25 meters in its natural habitat, though cultivated specimens are usually more manageable. It’s a slow-growing tree, which means patience is rewarded with a long-lived and resilient specimen.
The most enticing aspect of the Illawarra plum tree is undoubtedly its fruit. These are not true plums in the botanical sense but are the fleshy, edible cones of the tree. The edible part is the swollen, fleshy receptacle that surrounds the seed. They are typically ovoid in shape, about 2-5 cm long, and ripen from a green to a vibrant red or deep purple colour, usually between December and March in Australia. The flavour is often described as a unique blend of tart and sweet, with hints of pine, plum, and sometimes even a subtle spicy note. The texture is juicy and can be somewhat astringent when not fully ripe, but when at their peak, they are wonderfully refreshing.
Cultivating Your Own Illawarra Plum Tree
If you’re considering adding an Illawarra plum tree to your garden, here’s what you need to know about its cultivation:
-
Climate and Location: Illawarra plum trees are native to the coastal rainforests of eastern Australia, from southern Queensland to Victoria. They thrive in a temperate to subtropical climate. They are relatively hardy and can tolerate a range of conditions, including some frost once established. They prefer a location that receives plenty of sunlight, though they can also tolerate partial shade. Protection from strong winds is also beneficial.
-
Soil and Drainage: These trees are adaptable to various soil types, but they perform best in well-drained, fertile soil. Amending heavy clay soils with organic matter will improve drainage and aeration. They appreciate slightly acidic to neutral pH levels.
-
Planting: When planting an Illawarra plum tree, dig a hole twice the width of the root ball and just as deep. Gently remove the tree from its container, loosen any circling roots, and place it in the hole. Backfill with soil, compost, and a little native plant fertiliser if desired. Water thoroughly after planting and continue to water regularly, especially during dry periods, until the tree is established.
-
Watering: Young trees require consistent watering to establish a strong root system. Once mature, they are relatively drought-tolerant but will benefit from occasional watering during prolonged dry spells to ensure good fruit production.
-
Fertilising: While not overly demanding, a light application of a balanced, slow-release fertiliser or a composted organic fertiliser in spring can promote healthy growth and fruiting. Avoid over-fertilising, which can lead to excessive leaf growth at the expense of fruit.
-
Pruning: Illawarra plum trees generally require minimal pruning. Light pruning can be done to shape the tree, remove any dead or damaged branches, or to manage its size and form. Pruning is best carried out after fruiting.
-
Pest and Disease: Illawarra plum trees are generally resistant to most pests and diseases. Their natural resilience makes them a low-maintenance option for gardeners.

-

-

The Culinary Delights of the Illawarra Plum
The Illawarra plum is more than just a beautiful tree; it’s a culinary delight with a unique flavour profile. The fruit can be enjoyed fresh, but its true versatility shines in various culinary applications.
Harvesting: The fruit is ready to harvest when it has reached its full colour (deep red to purple) and is slightly soft to the touch. Gently twist or cut the fruit from the branch.
Preparation: The edible part of the fruit is the fleshy receptacle. The seed inside is not typically eaten. The skin is edible, and the flesh has a juicy texture. Some people prefer to remove the seed before using the fruit, while others find it easy to do so after processing.
Flavour: The flavour is a complex interplay of tartness and sweetness, with a refreshing, almost pine-like aroma. It’s a taste that is distinctly Australian and unlike any other fruit.
Illawarra Plum Recipes: A Taste of the Native Bush
Here are a few ideas to get you started with your Illawarra plum harvest:
1. Fresh Illawarra Plum Jam
This classic jam allows the unique flavour of the Illawarra plum to shine.
Ingredients:
- 1 kg ripe Illawarra plums, pitted and roughly chopped

- Place the saucepan over medium heat and stir until the sugar is completely dissolved.
- Bring the mixture to a rolling boil, stirring occasionally.
- Continue to boil, stirring frequently, until the jam reaches setting point. You can test this by placing a small amount of jam on a chilled saucer; if it wrinkles when pushed, it’s ready. This can take anywhere from 20-40 minutes, depending on the water content of your fruit.
- If the jam seems too thick, you can add a tablespoon or two of water to loosen it.
