Callistemon is a genus of shrubs in the family Myrtaceae, first described as a genus in 1814. The entire genus is endemic to Australia but widely cultivated in many other regions and naturalized in scattered locations. Callistemon species have commonly been referred to as bottlebrushes.
Blossoms are produced in spring simultaneously with the budding of the leaves and are produced on spurs and some long shoots. The 3 to 4 cm (1.2 to 1.6 in) flowers are white with a pink tinge that gradually fades, five petaled, with an inflorescence consisting of a cyme with 4–6 flowers.
Floral design or flower arrangement is the art of using plant materials and flowers to create a pleasing and balanced composition. Evidence of refined floristry is found as far back as the culture of ancient Egypt.
Roses are best known as ornamental plants grown for their flowers in the garden & sometimes indoors. They have been also used for commercial perfumery & cut flower crops. Some are used as landscape plants, for hedging & for other utilitarian purposes such as game cover & slope stabilization.
