MEXICAN HYDRANGEA, ROSE GLORY BOWER or PINK DIAMOND
Clerodendrum bungei or Mexican Hydrangea is a Perennial is native to China and is a member of the Verbenaceae family.
It is not a real “hydrangea” nor is it from Mexico*, but it’s still attractive, even if misnamed. The flower heads are very fragrant and are produced at the tops of 120mm to 150mm stems and occur from spring to late summer and can be up to 200mm in diameter. This Clerodendrum is deciduous in colder months.
It does spread by rhizomes (underground stems), thus forming a colony. Plant it where that habit will not create a problem. While it can grow in full sun, it needs far less water in half-day sun sites. It is drought tolerant and is a tough plant.
This plant is a butterfly attractant as a nectar source for adults and a food source for caterpillars of a number of species of butterflies
