    About Banksia spinulosa 'Birthday Candles'

    Banksia spinulosa 'Birthday Candles' is a compact Australian native dwarf shrub valued for its showy golden-yellow flower spikes that emerge through autumn and winter, resembling lit candles standing upright above the foliage. It is one of the most reliable flowering dwarf banksias in cultivation, bred for its tight compact form and prolific seasonal display.

    It performs best in full sun to part shade with free-draining acidic to neutral soil and is highly drought tolerant, coastal tolerant and low maintenance once established. The fine dark green foliage forms a dense rounded mound year-round, providing structure and texture even when not in flower, while the bold golden flower spikes draw honeyeaters and other nectar-feeding birds into the garden during the cooler months.

    As a feature shrub in native, coastal, modern and low-maintenance gardens, in mass plantings, borders, rockeries and large containers, Banksia 'Birthday Candles' brings reliable seasonal colour, native wildlife value and a compact manageable form that works at the front of the border or as a low feature mass.
