Flowers at the end of branches come in clusters, each flower is 2.5-5 cm diameter. The long bloom period from spring to fall is one of the reasons for its popularity, with the extreme drought tolerance being another. Many cultivars have scented flowers, coming in red, pink, white salmon and yellow. Double flowers are less common than single. Single flowers fall off after finishing, while double flowers turn brown and remain until trimmed off. | Flowers at the end of branches come in clusters, each flower is 2.5-5 cm diameter.
