Telopea truncata
Also called Waratah
The Tasmanian waratah is a multistemmed shrub, sometimes a small tree, native to cool, moist highlands of Tasmania, grown for its red flower heads. It does best in a cool climate with ample water and good drainage.
Telopea truncata, commonly known as the Tasmanian waratah, is a plant in the family Proteaceae. It is endemic to Tasmania where it is found on moist acidic soils at altitudes of 600 to 1200 m (2000–4000 ft). Telopea truncata is a component of alpine eucalypt forest, rainforest and scrub communities. It grows as a multistemmed shrub to a height of 3 metres (10 ft), or occasionally as a small tree to 10 m (35 ft) high, with red flower heads, known as inflorescences, appearing over the Tasmanian summer (November to February) and bearing 10 to 35 individual flowers. Yellow-flowered forms are occasionally seen, but do not form a population distinct from the rest of the species.
Collected by French botanist Jacques Labillardière in 1792–93, Telopea truncata was first scientifically described in 1805.
The flowers of the Tasmanian waratah provide ample nectar and hence are a food source for bird visitors to the garden. The species can be propagated by seed, though seedlings may succumb to damping off. Growing in a natural shady location delays flowering by two to four weeks, while growing in a cooler conditions (due either to latitude or altitude) can delay flowering by up to six weeks. Pruning flower heads can promote subsequent growth of leaves and branches. It grows best in a cool climate with ample water and good drainage, and has done well in cultivation in England. The Royal Horticultural Society gave it an Award of Merit in 1934 and a First Class Certificate in 1938. The relationship between light duration and intensity, temperature, vegetative growth and flower production is poorly known. Yellow forms in cultivation were originally propagated from a plant found on Mount Wellington.
The species is found in central, southern, and western Tasmania and is absent from warmer, dryer areas. It grows on moist acidic soils in wet sclerophyll forest or subalpine scrub at altitudes of 600 to 1200 m (2000–4000 ft). It is an understory component of subalpine forest stands of alpine ash (Eucalyptus delegatensis) and alpine yellow gum (E. subcrenulata), as well as Athrotaxis selaginoides–Nothofagus gunnii short rainforest, Athrotaxis selaginoides rainforest, Leptospermum-with-rainforest scrub, the tall Nothofagus–Atherosperma rainforest and Nothofagus–Phyllocladus short rainforest. It is occasionally found in the Leptospermum scoparium–Acacia mucronata forest community of western Tasmania.
The flowers of T. truncata were once used extensively for decoration. Geoffrey Smith observed in 1909 that the collection of the flowers for this purpose had caused the decline of some populations on Mount Wellington. The timber of larger specimens has been used for inlays; it has an attractive grain and a pale red color.
