Telopea speciosissima

Telopea speciosissima, commonly known as the New South Wales waratah or simply waratah, is a large shrub in the Proteaceae family. It is endemic to New South Wales in Australia and is the floral emblem of that state.

No subspecies are recognised, but the closely related Telopea aspera was only recently classified as a separate species. T. speciossisima grows as a shrub to 3 or 4 m (10–13 ft) high and 2 m (7 ft) wide, with dark green leaves and several stems rising from a pronounced woody base known as a lignotuber.

It is most renowned for its striking large red inflorescences (flowerheads) in spring, each made up of hundreds of individual flowers. These are visited by the eastern pygmy possum (Cercartetus nanus), birds such as honeyeaters (Meliphagidae), and insects.

The floral emblem for its home state of New South Wales, Telopea speciosissima has featured prominently in art, architecture and advertising, particularly since federation.

Commercially grown in several countries as a cut flower, it is also cultivated in the home garden, although it requires good drainage, yet adequate moisture, and is vulnerable to fungal disease and pests.

A number of cultivars with various shades of red, pink and even white flowers are available. Plantsmen have also developed hybrids with T. oreades and T. mongaensis, which are more tolerant of cold, shade and heavier soils.

The New South Wales waratah is a large erect shrub up to 3 or 4 metres (10–13 ft) in height with one or more stems. Arising vertically or near vertically from a large woody base, or lignotuber, the stems are little branched.

There is a spurt of new growth after flowering in late spring, with new shoots often arising from old flowerheads. The dark green leaves are alternate and usually coarsely-toothed and range from 13 to 25 cm (5–10 in) in length.

Enveloped in leafy bracts, the flowerheads develop over the winter and begin to swell in early spring, before opening to reveal the striking inflorescences. The exact timing varies across New South Wales, but flowering can begin as early as August in the northern parts of its range, and finish in November in the southern, more elevated areas.

Spot flowering may also occur around March in autumn. Containing up to 250 individual flowers, the domed flowerheads are crimson in colour and measure 7–10 cm (3–4 in) in diameter. They are cupped in a whorl of leafy bracts which are 5 to 7 cm (2–3 in) long and also red.

Variations are not uncommon. Some flowerheads may be more globular or cone-shaped than dome-shaped, and the bracts may be whitish or dark red. The tips of the stigmas of some inflorescences may be whitish, contrasting with the red colour of the rest of the flowerhead.
