Lemann's banksia is a Western Australian shrub or small tree with unusual hanging, honey-scented yellow flower spikes. It grows well in full sun and free-draining, alkaline soil, and it is killed by fire and regenerates from seed.

About
Banksia lemanniana, the yellow lantern banksia or Lemann's banksia, is a species of flowering plant in the family Proteaceae, native to Western Australia. It generally grows as an open woody shrub or small tree to 5 m (16 ft) high, with stiff serrated leaves and unusual hanging inflorescences. Flowering occurs over summer, the greenish buds developing into oval flower spikes before turning grey and developing the characteristic large woody follicles. It occurs within and just east of the Fitzgerald River National Park on the southern coast of the state. B. lemanniana is killed by bushfire and regenerates from seed.
Described by Swiss botanist Carl Meissner in 1856, Banksia lemanniana was named in honour of English botanist Charles Morgan Lemann. It is one of three or four related species all with pendent inflorescences, which is an unusual feature of banksias.
How to grow it
One of the easier Western species to grow, Banksia lemanniana has some horticultural potential in its attractive chocolate buds, green-yellow hanging flower spikes and large grey spikes with prominent follicles. It generally grows quite quickly, but nevertheless takes five to six years to flower from seed. It prefers a more alkaline rocky or sandy soil, with a nominal pH range from 6 to 7.5. It favours a sunny position and good drainage, and has been successfully cultivated in more humid climates on Australia's east coast. Seeds do not require any treatment, and take 27 to 43 days to germinate.
Where it grows
Banksia lemanniana is found near the southern coast of Western Australia, most of its population protected within Fitzgerald River National Park. Outside the park, it reaches the Ravensthorpe Range to the northeast and the rabbit-proof fence to the east, as well as isolated populations westwards as far as Pallinup estuary. The annual rainfall is 500–600 mm (20–24 in). It is found on the tops and slopes of hills as well as flatter areas on rocky or lateritic soil, as well as sand, in mallee scrubland or heath. Banksia lemanniana is relatively secure as much of its range lies within a National Park, and it is not a species collected for the cut flower industry. It is hence classified as Not Threatened under the Wildlife Conservation Act of Western Australia.
