There is some debate over whether the two species should be amalgamated.
Family: - Alliaceae
False Onion Weed refers to it similarity to Three-cornered Garlic (Allium triquetrum) which is often called Onion Weed. False may allude to the fact that it doesn't have an onion like odour.
Fragrant False Garlic.
A persistent, perennial herb to 1 m tall with clusters of sweet scented, 6 petalled flowers on a cylindrical stem in spring and 2-10, long shiny, strap-like leaves that arise from a bulb in autumn and wither over summer. It has an annually renewed bulb and produces many seeds and underground bulbils. It does not have the onion-like smell of Three-cornered Garlic.
The first leaves from the seed or bulbils are fine and thread-like. The first leaf from the bulb is fleshy.
2-10 strap-like, arising from a bulb (basal). Little or no onion-like smell when crushed. Shorter than or equal to the flowering stem.
Stipules - None.
Petiole - None.
Blade - 200-300 mm long by 4-20 mm wide, flat, strap-like, 17-20 lengthwise veins. 190-230 mm long by 2-9 mm wide. Tip pointed. Edges parallel. Base sheathing for less than one tenth of the flower stem (scape).
Stem leaves -
Flower stem - Erect, cylindrical, (150)300-600(1000) mm tall by 5 mm wide, hollow or sometimes solid for part of its length, unbranched.
Terminal umbel of 8-25 flowers. Flowers are on stalks (pedicels) in dense clusters which are subtended by two bracts (spathe) that overlap at the base and are at the end of a long stem (scape). Few to many flowered loose umbel. Pedicels (10)20-45 mm long, erect. Scape 300-600(1000) mm long. Spathe is persistent, about 10 mm long or less than half as long as the pedicels and has pale red brown markings. Flowers initially enclosed in spathe.
White to faint pink or faint purple, fragrant flowers with 6 petals and a conical base. Bisexual.
Ovary - Superior, 3 celled. 4-12 ovules per cell (loculus).
Style - terminal.
Stigma - entire.
Petals (tepals) - Six, 8-15 mm long by 3-5 mm wide with pointed tips. White to faint pink or faint purple with a pale green to brown marking on the mid vein. Conical tubular at the base.
Stamens - Short, attached to segments just above the base of the perianth. Half as long as the perianth
Filaments - 7-8 mm long, simple, linear and slightly broader at the base
Anthers - Yellow, Prominent. 6.
Oval capsule, 5-8 mm long with 3 segments (locules). Dehiscing loculicidally.
Black, many, angled, 2 mm long.
Bulbils are formed at the base of the bulb, but there are none on aerial parts of the plant.
Single, white globular bulb more than 15-20 mm wide producing many basal bulbils during the growing season. Fibrous but somewhat fleshy roots.
Bulb with membranous tunic.
Little or no onion-like odour when crushed.
Flowers in umbels.
Perianth of 6 segments connate into a short tube at base.
Pistil free from stamens.
Ovules usually 4-12 per loculus.
Adapted from Burbidge, Harden
Perennial. Leaves emerge from bulb in autumn and grow over winter. In spring the flowering stem elongates and produces terminal clusters of 6 petalled, white flowers. The flowers produce seed and the bulb regrows and many underground bulbils are produce also. Seed and bulbils germinate in autumn but don't usually produce flowers until the following seasons after the bulb has increased in size.
By seed, bulbils and bulbs.
September to December in NSW.
October to November in Perth, WA.
October to January in WA.
Seed Biology and Germination:
Bulbs and bulbils.
Population Dynamics and Dispersal:
Dispersed by water and ants mainly.
Dumping of garden waste is another common method of dispersal to new areas.
It has been cultivated as a garden plant and is common around old settlements.
Tends to occur in slightly depressed and moister parts of the landscape and in disturbed areas.
Temperate and Mediterranean.
Sands, sandy clay
Ornamental garden plant.
Weed of lawns, roadsides, disturbed areas, bushland and gardens.
It is a common weed of turf and gardens in temperate Australia.
Not recorded as toxic.
Management and Control:
Herbicides are the most effective method of control. Iodosulfuron provides good control in Kikuyu, Buffalo and Couch (but not Queensland Blue Couch) turf or lawn and some other perennial grass species.
It is difficult to control manually.
It is relatively tolerant to mowing and slashing.
Rarely a weed of crops.
Very difficult to eradicate manually because the bulblets break off easily and it produces quantities of seed.
For small areas use 1 g iodosulfuron(50g/kg) plus 25 mL Pulse in 10 L water and spray until just wet in winter and repeat for 2-3 years.
No other Nothoscordum species.
Other species in the Alliaceae family include:
Leek (Allium porrum)
Naples Onion (Allium neopolitanum)
Three-cornered Garlic (Allium triquetrum)
Cultivated species include Allium, Agapanthus, and Tulbaghia.
