Callistemon: Whispers of the Australian Bush

What are Callistemons?

The Callistemon genus, commonly known as Bottlebrush, is a group of approximately 70 species of flowering shrubs and trees native to Australia. Their most distinctive feature is, of course, their vibrant, bottlebrush-shaped flowers, which come in a dazzling array of colors, including crimson, pink, white, and even green! These plants are incredibly adaptable, thriving in diverse conditions, from coastal areas to drier inland regions. But their beauty is only part of the story. They play a crucial role in the Australian ecosystem, attracting pollinators and providing food and shelter for wildlife.
