Vanilla Lily

Arthropodium milleflorum (DC.) J.F.Macbr.

Arthropodiummilleflorumis atuberous perennialherb belonging to theAsparagaceaefamily. It is commonly known as the Vanilla Lily, due to the slight scent emitted from the flowers.

The species has a wide distribution along the east coast, from Queensland to South Australia and Tasmania. It is particularlyprevalent on the Southern Tablelands (includingthe ACT) and in eastern New South Wales. It favours moist, grassy, sheltered slopes in open eucalypt forest, but can also be found in woodland, montane forest, and other grassland.It is listed as endangered in South Australia due to illegal collection for the horticulture trade, but is not considered at risk elsewhere.

The flowers appear between November and February on spreading or branching stems growingto 1 m. The flowers are hermaphroditic and consist of sixwhite-lilac petals, purple anthers and distinctive white or cream hairy filaments.Fruitsdevelop betweenDecemberand March and are globularcapsulesto 5mm indiameter. At the base of the plant are dark green, strappy leaves, which grow to about 60 cm long.

The plant has traditionally been used as a food source by some Aboriginal groups. The tubers are eaten raw or roasted. The flowers are also edible. The presence of flowers may have signalled to hunters that game animals, such as bandicoots (which eat the tubers of this species), were nearby.

The plant has many features which make it ideal for the home garden or landscaping. It is low maintenance, frost tolerant and has relatively low water requirements. Some sources suggest it can go dormant in the drier months, which may make it more resilient to drought. A key feature of the plant is its flowers, which are pleasantly scented, insect attracting, and hang in dainty panicles along the arching stems. It is ideal planted en masse in a meadow, path border,rockery, or under trees,and can also grow in a pot.

In nature the plant is usually propagated by birds or small mammals eating the fruit and spreading the seed. It can self-seed to some extent, but does not become invasive. In cultivation, it is easiest to propagate by seed, which must be collectedbefore they are shed from the fruit. Store seed in a cool, dry, place and sow into seed-raising trays in autumn or early spring. You may also be able to propagate by tuber division, dividing in winter and transplanting in spring.
