The Hairpin Banksia (Banksia spinulosa) is a species of woody shrub, of the genus Banksia in the Proteaceae family, native to eastern Australia. Widely distributed, it is found as an understorey plant in open dry forest or heathland from Victoria to northern Queensland, generally on sandstone though sometimes also clay soils. It generally grows as a small shrub to 2 metres (7 ft) in height, though can be a straggly tree to 6 metres (20 ft).
Banksia spinulosa ‘Birthday Candles’ is the original Banksia spinulosa Dwarf, making it one of the best known. It is unfortunately one of the most expensive and in my view not one of the hardiest. It comes from southern NSW near Ulladullah and tends to turn up its toes in areas with humid summer months. This is unfortunate as it is a lovely shrub with an even compact shape and fine bright green leaves. It grows reliably to .5metres high x 1 metre wide.
