Vanilla Lily – Arthropodium milleflorum is a graceful edible Australian native lily grown for its pale mauve, vanilla-scented flowers, attractive grass-like foliage and nutritious underground tubers. It is a beautiful plant for native food gardens, grassland-style plantings, cottage-style native gardens, rockeries, pots, habitat gardens and pollinator-friendly landscapes.
At Sylvaterre Native Nursery, Vanilla Lily grows in a similar seasonal rhythm to Chocolate Lily, but it generally re-emerges and flowers 1–4 weeks later. This makes it especially useful for extending the native lily season, adding another wave of scented flowers after Chocolate Lily begins its display.
Mature Vanilla Lily plants are usually slightly smaller than Chocolate Lily, with slightly broader foliage and shorter flower spikes. The foliage difference is most obvious in re-emerging plants, when Vanilla Lily produces a stronger, broader-leaved clump before sending up its pale mauve flower stems.
The plant grows from underground tuberous roots and may retreat during hot or dry conditions before re-shooting when seasonal conditions improve. In the garden it is best grown in partial shade to full sun, with partial shade preferred in hotter inland areas. It is frost tolerant, drought tolerant once established, and highly suitable for pots.
Flowers
• Soft pale mauve flowers with a gentle vanilla fragrance.
• Flowering is mainly from late spring to summer.
• At Sylvaterre, flowering usually begins 1–4 weeks later than Chocolate Lily.
• Flowers are carried on fine, branched stems above the foliage.
• Individual flowers are delicate and starry, with attractive darker anthers.
• Flowers are edible and may be used sparingly as a decorative garnish.
Foliage
• Grass-like foliage emerging from the base of the plant.
• Leaves are slightly broader than Chocolate Lily foliage.
• Re-emerging plants show the foliage difference most clearly.
• Mature plants are slightly smaller than Chocolate Lily, with shorter flower spikes.
• Foliage may die back during hot, dry or dormant periods.
• Plants re-emerge from underground tubers when conditions are suitable.
Cultivation
Soil:
Best in well-drained soil, including loam, sandy loam and clay loam where drainage is suitable. Avoid sites that remain waterlogged for long periods.
Sunlight:
Prefers partial shade to full sun. In hot inland gardens, partial shade is usually better than harsh all-day summer sun.
Watering:
Water regularly during establishment. Once established, Vanilla Lily is drought tolerant, but plants will grow, flower and tuber better with some seasonal moisture.
Frost tolerance:
Frost tolerant once established.
Drought tolerance:
Drought tolerant once established. During dry periods, plants may retreat underground and re-emerge when conditions improve.
Dormancy:
Vanilla Lily may become dormant after flowering or during hot, dry weather. Mark the planting position so dormant plants are not accidentally weeded out.
Pruning / Maintenance:
Remove spent flower stems after flowering or once seed has matured. Allow foliage to die back naturally so energy returns to the tubers.
Fertiliser:
Use a low-phosphorus native fertiliser sparingly if required. Avoid heavy feeding.
Food and Nutrition Information
Vanilla Lily has a long history as an Aboriginal food plant. The edible part is the tuberous root, which may be eaten raw when young or roasted. Young tubers are crisp, watery and mildly sweet, while older tubers can become more bitter.
The edible flowers can also be used sparingly as a garnish, but the major food value is in the underground tubers.

Iron Super-Vege: Comparison with Spinach, Broccoli and Carrot
Vanilla Lily tubers are unusually rich in iron for an edible root crop. Per 100 g edible portion, Vanilla Lily contains 7.8 mg iron, which is far higher than many common vegetables usually thought of as nutritious garden foods.
Percentage comparison
Compared with raw Spinach, Vanilla Lily tubers contain:
• 74% less fat
• 65% less sodium
• 188% more iron
• 79% less potassium
Compared with raw Broccoli, Vanilla Lily tubers contain:
• 75% less fat
• 983% more iron
• 65% less potassium
Compared with raw carrot, Vanilla Lily tubers contain:
• 133% more protein
• 45% less sodium
• 3,614% more iron
• 55% less potassium
Why This Matters
Vanilla Lily is a genuinely exciting edible native plant because it combines very high plant-based iron with low sodium, low fat and moderate potassium.
This makes it especially interesting for vegetarians and vegans wanting to increase plant-based iron intake. Like other plant foods, the iron in Vanilla Lily is non-haem iron, so absorption may be improved by eating it with vitamin C-rich foods such as citrus, berries, tomatoes, capsicum or leafy greens.
The low sodium level is also a major positive. At 28 mg sodium per 100 g, Vanilla Lily tubers sit well below the usual low-salt threshold of 120 mg sodium per 100 g. Combined with their much lower potassium level than spinach, broccoli and carrot, Vanilla Lily tubers may be a very promising food plant for people seeking kidney-conscious, lower-sodium edible plants.
People with kidney disease, dialysis requirements or potassium, phosphate or protein restrictions should still follow advice from their doctor or renal dietitian, because kidney diets vary between individuals.
Food Safety Note
Only eat plant material that has been correctly identified and grown without pesticides, herbicides or other contaminants. Harvest only from plants you are confident are Arthropodium milleflorum. If eating native tubers for the first time, try a small amount first.
Uses
• Edible native tuber plant for bushfood and native food gardens.
• Excellent for vegetarians and vegans interested in plant-based iron.
• Potentially useful in kidney-conscious low-sodium food gardens, with medical advice where kidney disease is present.
• Suitable for pots and containers.
• Beautiful in native cottage gardens and grassland-style plantings.
• Useful in rockeries, borders, meadow-style gardens and small spaces.
• Attractive seasonal companion to Chocolate Lily.
• Good for pollinator-friendly gardens.
• Suitable for frost-prone and drought-tolerant native gardens once established.
• Valuable in educational gardens focused on Aboriginal food plants and native plant diversity.
Habitat Value
Vanilla Lily – Arthropodium milleflorum provides pale mauve seasonal flowers for native bees, butterflies and other small pollinating insects. Its grass-like foliage helps create the fine ground-layer structure needed in native grassland, woodland and habitat-focused gardens.
When grown with other native lilies, daisies, grasses and small shrubs, Vanilla Lily contributes to a layered, biodiverse planting that supports insects and the wildlife that feeds on them.
Natural Range
Arthropodium milleflorum is native to eastern and south-eastern Australia, including Queensland, New South Wales, the Australian Capital Territory, Victoria, South Australia and Tasmania. It occurs in a range of habitats including grasslands, open woodlands, forests, sheltered slopes and seasonally moist areas.
Conservation / Rarity Status
Arthropodium milleflorum is not treated as nationally threatened. It is still a valuable native ground-layer plant because many native grassland and open woodland communities have been heavily reduced by clearing, grazing, weed invasion and soil disturbance.
Growing Vanilla Lily helps keep edible native lilies in cultivation and supports interest in diverse Australian native ground-layer plants.
Growing Tips
Plant in partial shade to full sun in a well-drained position. In hot inland gardens, give it morning sun or filtered light rather than harsh afternoon exposure.
Water through the first growing season to establish strong roots and tubers. Once established, reduce watering and allow plants to follow their natural seasonal cycle.
For the best display, plant Vanilla Lily in groups or drifts so the pale mauve flower stems rise through surrounding native grasses and small wildflowers. In pots, use a free-draining native potting mix and avoid overwatering while dormant.
Shipping Note
At Sylvaterre Native Nursery, every plant is treated with care and respect. Unlike many online nurseries that ship tubestock lying flat — often stacked on top of each other in standard Australia Post boxes — all Sylvaterre plants are shipped upright in custom-made cardboard plant boxes. This helps ensure they arrive healthy, happy, and ready to thrive in your garden or pots. See our shipping cartons in the image gallery.
