 Repeated mild burning results in an umbrella shaped growth habit.Seed dispersal and survival greatly depends on the symbiosis of many Proteaceae with native ant species, in particular "Anoplolepis steingroeveri" and "Pheidole capensis", that carry the fruits to their underground nests, where the elaiosome is eaten, leaving a slick and hard seed underground, safe from consumption by rodents and birds and overhead fires.The seeds would germinate after a fire, due to the larger temperature variations after the overhead vegetation has vanished and chemicals from the charcoal seep with the winter rains and soak the seeds.
