This robust shrub grows above 4 meters and produces cylindrical red flower spikes 6 to 10 centimeters in length, for which it is aptly named the bottlebrush. Sometimes the pollen gives these spikes a bright yellow flush. When crushed, the leaves produce an agreeable fragrance, which has led to their use in tea. A pinch of these seeds is enough to germinate a forest.
