The name Pachystachys comes from the Greek for "thick spike", referring to the flower heads. [3] The genus is closely related to Justicia . [2]

The species P. coccinea, P. lutea and P. spicata are found in cultivation. They can be grown outside in subtropical gardens in areas where the temperature does not fall below 10 °C (50 °F). Elsewhere, they can be grown under glass or as houseplants. [2]

Banksias range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts.

<i>Dahlia</i> Genus of flowering plants in the daisy family Asteraceae

<i>Banksia coccinea</i> Species of shrub or small tree

Banksia coccinea, commonly known as the scarlet banksia, waratah banksia or Albany banksia, is an erect shrub or small tree in the family Proteaceae. Its distribution in the wild is along the south west coast of Western Australia, from Denmark to the Stokes National Park, and north to the Stirling Range, growing on white or grey sand in shrubland, heath or open woodland. Reaching up to 8 m (26 ft) in height, it is a single-stemmed plant that has oblong leaves, which are 3–9 cm (1.2–3.5 in) long and 2–7 cm (0.8–2.8 in) wide. The prominent red and white flower spikes appear mainly in the spring. As they age they develop small follicles that store seeds until opened by fire. Though widely occurring, it is highly sensitive to dieback and large populations of plants have succumbed to the disease.
