Murnong: A Native Superfood’s Revival and Cultivation Guide
For millennia, the Murnong ( Microseris lanceolata ), also known as the yam daisy, was a cornerstone of Aboriginal Australian diets, particularly in the fertile south-eastern regions. Its starchy, tuberous roots, rich in carbohydrates and possessing a subtly sweet, nutty flavour, provided essential sustenance. However, with the advent of European colonisation, traditional foodways were disrupted, and the Murnong, like many native flora, faded from widespread cultivation and consumption. Today, a burgeoning movement is dedicated to reviving this remarkable plant, recognizing its potential as a sustainable, nutritious, and culturally significant food source. This article delves into the fascinating world of Murnong cultivation, offering a comprehensive guide for those interested in reintroducing this ancient superfood to our plates.
The Enduring Legacy of Murnong
The Murnong’s significance extends far beyond its nutritional value. It was a vital component of complex Aboriginal agricultural practices, where careful management of native grasslands ensured a continuous supply of Murnong tubers. Indigenous peoples developed sophisticated techniques for harvesting, storing, and propagating the plant, demonstrating an intimate understanding of its ecological needs. The tuber was typically roasted in earth ovens, a method that unlocked its delicious flavour and rendered it easily digestible. The widespread distribution of Murnong across southern Australia speaks to its adaptability and importance as a staple food across diverse landscapes.

Cultivation Guide: From Seed to Harvest
Cultivating Murnong requires patience and an understanding of its specific needs. While it can be challenging to establish, the rewards are well worth the effort.
1. Sourcing Seeds and Tubers:
- Ethical Sourcing: It is paramount to source Murnong seeds or tubers ethically and sustainably. Connect with Indigenous cultural centres, native plant nurseries specializing in Indigenous flora, or reputable conservation organizations. Avoid disturbing wild populations.
- Seed vs. Tuber Propagation: Murnong can be propagated by both seeds and tubers. Seeds offer a more widely available starting point, but tuber propagation can lead to faster establishment and a higher success rate for experienced growers.
2. Site Selection and Preparation:
- Sunlight: Murnong thrives in full sun to partial shade. Choose a location that receives at least six hours of sunlight per day.
- Soil: The ideal soil for Murnong is well-draining, sandy loam with a slightly acidic to neutral pH (5.5-7.0). While Murnong is adaptable, it dislikes waterlogged conditions. Amend heavy clay soils with compost and coarse sand to improve drainage.
- Weed Control: Prior to planting, thoroughly remove any weeds, as they will compete with young Murnong plants.
3. Sowing Seeds:
- Timing: The best time to sow Murnong seeds is typically in autumn (March to May) or early spring (August to October), depending on your local climate. This allows seeds to germinate with the cooler, moister conditions.
- Method:
- Direct Sowing: Sow seeds directly into the prepared soil, about 5-10 mm deep. Space seeds approximately 15-20 cm apart.
- Stratification: Murnong seeds often benefit from stratification (a period of cold, moist treatment) to break dormancy. You can achieve this by sowing seeds in a tray filled with moist seed-raising mix and placing it in the refrigerator for 4-6 weeks before sowing outdoors.
- Watering: Water gently after sowing and keep the soil consistently moist but not waterlogged.
4. Planting Tubers:
- Timing: Plant tubers in late autumn or early spring when the soil is cool and moist.
- Method:
- Dig small holes approximately 5-10 cm deep.
- Place tubers in the holes, ensuring they are covered with soil. Space tubers about 20-30 cm apart.
- Water thoroughly after planting.
5. Watering and Care:
- Establishment: During the initial establishment phase, regular watering is crucial, especially during dry periods.
- Mature Plants: Once established, Murnong is relatively drought-tolerant. However, consistent moisture during the flowering and tuber development stages will promote better yields. Avoid overwatering.
- Weeding: Continue to keep the area around young Murnong plants free of weeds. As the plants mature and form a dense groundcover, they will naturally suppress weed growth.
- Fertilizing: Murnong generally does not require heavy fertilization. A light dressing of compost or well-rotted manure in spring can be beneficial. Avoid excessive nitrogen, which can promote leaf growth at the expense of tuber development.
6. Pests and Diseases:
Murnong is generally a hardy plant with few pest and disease issues. However, keep an eye out for:
- Slugs and Snails: These can be a problem for young seedlings. Use natural deterrents like crushed eggshells or beer traps.
- Aphids: In some cases, aphids may attack new growth. A strong jet of water or insecticidal soap can be effective.
- Root Rot: This is primarily caused by poor drainage. Ensure your soil is well-draining to prevent this.
7. Harvesting:
- Timing: The best time to harvest Murnong tubers is after the plant has finished flowering and the leaves have begun to die back, typically in late spring or early summer (November to January). This indicates that the energy has been stored in the tubers.
- Method:
- Gently loosen the soil around the base of the plant with a fork or spade.
- Carefully unearth the tubers. They can vary in size and shape.
- Harvest only what you intend to use or store. Leaving some tubers in the ground allows for natural regeneration.
8. Storage:
- Fresh: Freshly harvested Murnong tubers can be stored in a cool, dark, and dry place for a few weeks.
- Drying: For longer-term storage, Murnong can be sliced and dried in the sun or a dehydrator until brittle. Dried tubers can be ground into flour or stored whole.
Murnong in the Kitchen: Recipes and Preparations
The culinary potential of Murnong is vast, offering a delightful journey into ancestral flavours. Its subtle sweetness and nutty notes make it a versatile ingredient.
