Bottle Brush Plant. As the name suggests, it features bristly flowers blooming at the ends of the stems, which reminds people of a traditional bottle brush. The name is derived from the greek words kallos, meaning beauty, and stemon, meaning stamen, describing the coloured stamens, the showy part of the flowers.
It belongs to the myrtaceae family and the binomial name for this plant is callistemon citrinus. People usually grow it as a bottle brush shrub or tree that makes a perfect adornment for a small garden under windows or borders. Callistemons will grow in most.
