Ribwort Plantain

Plantago lanceolata

Appearance

  • A tussock-like, rosette plant.
  • Size: tussock up to 30 cm high and wide with a flower stalk up to 1 m high.
  • Leaves: long, sword-shaped and forming a clump. Each individual leaf is 8 – 20 cm long, 1 – 3 cm wide and usually stands upright. There are five veins running down each leaf.
  • Flowers: small and initially cream, but turn brown rapidly. They grow on top of a ridged, 1 m high flower stem growing from the centre of the tussock of leaves. The flowers form a tight, cylindrical cluster which is 1 – 7 cm long.
  • Fruit/seed: a black to brown seed pod, 3 – 4 mm long contains 1 – 2 yellow to pale brown seeds.

What to Observe

  • First fully open single flower (at the base of a cluster)
  • Full flowering (record all days)
  • End of flowering (when 95% of the flowers have faded)

ClimateWatch Science Advisor

We expect plants to start shooting and flowering earlier in the year as a result of climate change warming the Earth. They may also start appearing in new areas, as warmer temperatures enable them to live in environments that were previously too cold for them.

When To Look

  • From September through to May.
  • Flowers appear from September to April .

Where To Look

  • In all Australian states except the Northern Territory.
  • In woodland, grassland, disturbed sites, pastures, lawns and gardens in coastal and inland regions.
  • Look in gardens and disturbed areas, for examples sports ovals and roadsides.

  1. What Else?

    Variable Plantain (Plantago varia): its leaves usually have a toothed, or jagged, edge (not smooth like the Ribwort Plantain) and there is a dense tuft of reddish-brown hairs at the base of each leaf. Also, its flower stem can be shorter, only growing to a height of about 36 cm.

  1. Did You Know?

    It is classified as a weed in some areas and it may contribute to hayfever.

    It is native to Europe and northern and central Asia.
