Two species of Banksia are found on Mount Henry Peninsula, B. attenuata (candlestick banksia) and B. menziesii (firewood banksia). B. attenuata flowers from spring into summer and the B. menziesii flowering occurs in autumn and winter, the presence of both these species on Mount Henry Peninsula means that at any time during an annual period, at least one of the species of Banksia will be in flower, This is a major factor in the support of Mount Henry Peninsula's bird population.
