 No seed is set when pollinators are excluded, indicating that seed set must be pollinator-limited. About 96 % of fertilized follicles mature, and about 82 % of seeds mature. These are very high numbers for Banksia, indicating that there are no problems with nutrient supply. This species produces an unusually high number of old flowerheads, or cones, per plant — typically more than 500. However, there are an unusually low number of follicles per cone — often only one. Thus the number of follicles per plant ends up roughly average for a Banksia species.
