Animal vectors which pollinate these flowers are nectar feeding birds, such as Hummingbirds and insects. Fertilisation methods involve using soil rich in organic components such as manure. Bottle brush plants require extreme heat to release their seeds and usually disperse their seeds after bush fires. Bottle brush plants flower commonly in the warmer months of the year and produce many flowers. The floral morphology of the Bottle Brush consists of small petals and a bright, distinctive flower which is often red. The most obvious part of the bottle brush unlike other flowers is the stamens. Each flower which extends from the fruiting capsule is an individual flower.

These colour of flowers ranges from pink, mauve, green and cream.
