The sickle-leaf conebush is a perennial plant that flowers in August (4). As with all Leucadendron species, the male and female inflorescences are borne on separate plants (2). Beetles are the main pollinators, but sunbirds, sugarbirds, flies and wasps are all attracted to the plants by the sweet, sugar-rich nectar and the conspicuously coloured bracts (4). After pollination, female plants retain the winged seeds in the woody cone until a natural fire, which kills the parent, exposes them to the wind, dispersing the seeds across the landscape. Retaining the seeds on the plant reduces their loss to ground dwelling grazers, such as rodents. The germination of seeds is stimulated by a series of warm days, followed by cool nights at the beginning of autumn, while the commencement of winter rains encourages the growth of the young plant (2).
