💰 Price: Package of 2 seeds

Australian Ginger (Alpinia caerulea), also known as native ginger, is a striking perennial herb in the Zingiberaceae family found in rainforests and wet sclerophyll forests across eastern Australia. Growing naturally from the Gosford district to the Cape York Peninsula, it thrives in both coastal and sub-coastal regions, and can even be found in New Guinea. The plant is famous for its rhizomatous growth pattern, arching stalks, and large glossy leaves.

Plant Features:

• The plant grows to a height of 2-3 meters (6.7–9.8 feet).

• Leaves are dark green on top and lighter below, up to 40 cm (16 inches) long and 10 cm (3.9 inches) wide, with a smooth, glossy texture.

• Inflorescences are terminal on the stalks, up to 30 cm (12 inches) long, containing white flowers.

• Fruits are blue, spherical capsules, about 1 cm (0.39 inches) in diameter, containing black seeds set in white pith.

Ecology:

• This plant plays an important role in the ecosystem, serving as a host species for the larvae of the banded demon butterfly (Notocrypta waigensis).

• It is also a favorite food for various wildlife, including brush turkeys, southern cassowaries, king parrots, and even Australian rodents like the giant white-tailed rat.

• Birds such as crimson rosellas and regent bowerbirds enjoy the fruit, making it a valuable part of the rainforest habitat.

Cultural and Medicinal Uses:

• For the Kuku Yalanji people of far northern Queensland, Alpinia caerulea has significant traditional uses. The rhizomes were eaten, and the leaves were used to cover shelters or wrap meat for cooking in earth ovens.

• The fruit and young shoots of this plant are edible. The young shoots offer a mild ginger flavor, while the white flesh surrounding the seeds is crisp and acidic, often chewed to moisten the mouth during long walks. The seeds are typically discarded after chewing.

Planting Instructions:

1. Planting Time:

   • Australian Ginger seeds can be planted year-round, but the best time to sow is in spring or early summer for optimal growth.

2. Soil and Location:

   • Choose well-drained, moist, and rich soil that is slightly acidic to neutral. The plant thrives in shady to partially shaded areas, simulating the rainforest understorey environment.

   • Location: Plant in an area with indirect sunlight or filtered light.

3. Planting Depth:

   • Plant seeds slightly covered with soil, about 1–2 cm deep, ensuring they are kept consistently moist but not waterlogged.

4. Watering:

   • Keep the soil consistently moist during the growing season, especially in the early stages of growth. However, avoid letting the soil become waterlogged as this may harm the roots.

5. Spacing:

   • Space plants around 30–40 cm apart to allow for their wide growth and ensure proper airflow between them.

6. Germination:

   • Germination can take 1–3 months, so be patient. Keep the soil warm and moist, and check for sprouting every few weeks.

Harvesting:

• The rhizomes of the Australian Ginger can be harvested after 2-3 years of growth, once the plant is fully established.

• The fruits will ripen from September to April, and should be picked when they turn blue and feel slightly soft to the touch. These can be used in traditional recipes or consumed raw.
