Growth Habit: Plantains are common weeds throughout Tasmania. The most common species is Plantago lanceolata. This species develops a leafy rosette up to 30cm wide and high. It has mid to light green leaves that have 3-7 longitudinal veins.
Type of Plant: A low growing perennial.
Flowers: The flowers grow in tight clusters which are 1 to 2.5cm long. Individual flowers are quite small and insignificant.
Fruit/Seed: Seeds are black to brown in colour. Germination occurs autumn to winter.
Dispersal: Seeds fall from the seed head and may be carried short distances on wind. Soil and water movement may move them further from the parent plant.
Distribution: Plantain can be found in lawns, gardens, most pastures and virtually all roadsides.
Status: Undeclared in Tasmania.
- Plantain may contribute to hayfever.
- Infestations can become quite dense in run down lawns and pastures, excluding desirable grasses.
- Some biodynamic farmers promote plantains as a deep-rooted supplement to traditional pasture species as they can access nutrients deeper in the soil than most grasses.

- Grubbing (all year). Ensure entire plant is removed especially the long taproot.
- Cultivation (all year). Breaks up plantain clumps. Follow up with establishment of a competitive pasture or crop.
- Herbicide (spring, summer and autumn). Herbicides registered in Tasmania include dicamba, MCPA, glyphosate, 2,4-DB and 2,4-D.
N.B. Always check the herbicide label before use.
