Gymea Lily

Doryanthes excelsa

Appearance

  • Giant tussock-like, rosette plant.
  • Size: up to 2.5 m high with a flower stalk up to 5 m high!
  • Leaves: long, sword-shaped and forming a clump. Each individual leaf is 1 – 2.5 m long and about 10 cm wide. Shorter leaves up to 30 cm long are found along the flower stem.
  • Flowers: located at the top of a single flower stem which grows from the centre of the tussock of leaves. The stem is 2 – 5 m high upon which the flowers form a cluster up to 70 cm in diameter. The individual flowers are bright red (or rarely white), trumpet-shaped and 10 – 16 cm long.
  • Fruit/seed: a red-brown, woody seed pod, which is 7 – 10 cm long, contains flat, brown seeds which are 1.5 – 2.5 cm long. 

What to Observe

  • First fully open single flower
  • Full flowering (record all days)
  • End of flowering (when 95% of the flowers have faded)
  • Open seed pods (record all days) - carefully observed so as not to damage the flowering stalk

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 spring through summer.
  • Flower stem emerges from the tussock of leaves during winter.
  • Flowers appear in spring and summer.
  • Seed pods appear after flowers.
  • Seed pods split open in January or February

Where To Look

  • It is naturally found along the east coast of New South Wales, from Newcastle to Wollongong, and also in a few isolated regions on the North Coast.
  • However, it has proven adaptable to a range of climates and is now also grown in Melbourne, Brisbane, Perth and Adelaide
  • In open forest and woodland, and also in urban areas, in parks, gardens and along roadsides.
  • Look in urban areas, particularly in parks and along roadsides.

Above, the left and middle maps show the modelled habitat suitability for the the species under current and potential future climate conditions. The colours indicate the predicted habitat suitability from low (white) to high (dark red).

The future habitat suitability is modelled for the year 2070 under a climate change scenario that represents 'business as usual' (RCP 8.5). The map on the right shows how the range of the species might change between now and 2070, with orange areas indicating where the species might disappear, green areas where the species range might expand, and blue areas where the habitat is predicted to be suitable for the species now and in the future.

The models for this species were run in the Biodiversity and Climate Change Virtual Laboratory. Please note that while models can be very informative, they are only a representation of the real world and thus should always be viewed with caution. You can read more about the science behind these models here.

  1. What Else?

    Waratah (Telopea speciosissima): has shorter leaves (8 – 28 cm long), usually with serrated edges, that don’t grow in a clump or tussock from the ground. The flower stem is also much shorter, and the flower cluster much smaller (only 7 – 10 cm in diameter).

  1. Did You Know?

    Its genus name Doryanthes (meaning spear and flower), and its species name excelsa (meaning high), both refer to its tall flower stem.

    Indigenous Australians used to roast the stems and roots of the Gymea Lily. They made the roots into a type of cake that was eaten cold.

    When grown from seed, the flowering stems take 5 – 20 years to develop.
