Apple Berry – Billardiera scandens – Bush Tucker Food
Billardiera scandens, commonly known as Apple Berry, Climbing Apple Berry, Bomula or Karrawang, is an attractive Australian native plant grown both for its edible fruit and its ornamental value in the garden.
Naturally occurring in coastal and near-coastal regions of eastern Australia, particularly throughout New South Wales and Victoria, this evergreen species grows as a scrambling shrub or light climber in open forest and woodland environments.
The soft, velvety new foliage provides year-round interest, while the unusual greenish-yellow tubular flowers appear from winter through to early summer. These are followed by decorative purple to blue berries that are edible when fully ripe.
The fruit has long been used as a bush tucker food. Often referred to as Sweet Apple Berry, the flavour is said to resemble apple with a slight hint of aniseed. The berries can be eaten fresh from the plant or used in cooking, and have traditionally been dried and stored in a similar way to sultanas.
Although usually described as a climber, Billardiera scandens is perhaps better considered a scrambler. It can be allowed to wander naturally through surrounding vegetation or easily trained onto a trellis, fence or support structure.
While becoming more popular in native gardens, plants can still be somewhat difficult to find in mainstream nurseries.
Growing Billardiera scandens
Apple Berry is a relatively easy native plant to grow once established and adapts well to a range of garden situations.
For best results, grow it in a humus-rich soil that retains some moisture while still providing good drainage. Consistent moisture encourages stronger growth, heavier flowering and better fruit production.
The plant performs best in part shade or filtered sunlight. Morning sun with protection from hot afternoon sun is ideal, particularly in warmer climates. In cooler districts and higher altitude areas it will often tolerate full sun.
A layer of organic mulch helps maintain even soil moisture and improves soil structure over time.
Once established, Apple Berry has moderate drought tolerance, although prolonged dry conditions may reduce flowering and fruit production.
Care
The natural habitat of Billardiera scandens is generally open woodland and dry forest environments.
In cultivation, the preferred growing conditions are a moist but well-drained soil enriched with organic matter and a position with good morning sun or filtered shade.
Plants grown under suitable conditions will develop denser foliage, produce more flowers and generally yield larger crops of fruit.
Pruning is rarely required, although occasional trimming after fruiting can be used to maintain shape and encourage bushier growth.
Bush Tucker Uses
The edible berries are the main attraction of Billardiera scandens.
Fruit develops after flowering and gradually ripens to a blue-purple colour. Fully ripe fruit has a sweet flavour often compared to apple with subtle aniseed notes.
The berries may be:
- Eaten fresh from the plant.
- Added to fruit salads.
- Used in jams and preserves.
- Added to desserts.
- Dried for later use.
As with many Australian native food plants, harvesting is best carried out when the fruit is fully ripe for maximum flavour.
Landscaping Uses
Apple Berry is a versatile native plant that can be incorporated into many garden styles.
Popular uses include:
- Training over a trellis or fence.
- Growing through larger native shrubs.
- Understorey planting in native gardens.
- Wildlife-friendly gardens.
- Bush food gardens.
- Informal cottage-style plantings.
- Courtyard and small-space gardens.
Its relatively restrained growth habit makes it easier to manage than many vigorous climbing plants.
Propagation
Propagation is usually from seed.
Fresh seed generally provides the best results, although germination can be slow and erratic. The seed coat is relatively hard and some form of scarification or pre-treatment is often used to improve germination rates.
Seedlings may take several weeks or even months to emerge.
Propagation from semi-hardwood cuttings is sometimes possible, although success rates are generally lower than with seed.
Problems
Billardiera scandens is generally a reliable and trouble-free plant.
The most common issues are related to growing conditions:
- Poor flowering may result from excessive shade.
- Reduced fruit production is often linked to insufficient sunlight.
- Waterlogged soils can lead to poor growth and root problems.
- Extended dry periods may reduce flowering and fruit set.
Providing good drainage and regular moisture usually prevents most problems.
