Clerodendrum is a genus of flowering plants in the family Lamiaceae.[2] Its common names include glorybower, bagflower andbleeding-heart. It is currently classified in the subfamily Ajugoideae, being one of several genera transferred from Verbenaceae to Lamiaceae in the 1990s, based on phylogenetic analysis of morphological and molecular data.[3]
Estimates of the number of species in Clerodendrum vary widely, from about 150[4] to about 450.[2] This is partly because about 30 species have been transferred to Rotheca,[5][6] about 30 more to Volkameria, and 1 to Ovieda.[4] The type species for the genus is Clerodendrum infortunatum.[7] It is native to Sri Lanka and the Andaman Islands.[8]
The genus is native to tropical and warm temperate regions of the world, with most of the species occurring in tropical Africa and southern Asia, but with a few in the tropical Americas and northern Australasia, and a few extending north into the temperate zone in eastern Asia.[9]
They are shrubs, lianas, and small trees, usually growing to 1–12 m (3 ft 3 in–39 ft 4 in) tall, with opposite or whorled leaves. C. floribundumcan grow to 30 m (98 ft) tall.[10] Clerodendrum fistulosum and Clerodendrum myrmecophila have hollow stems that are inhabited by ants.[9]Clerodendrum trichotomum is a common ornamental in warmer parts of the world.[9] Eight other species are also grown in the tropics for their abundant and attractive flowers.[11] One of these, Clerodendrum macrostegium, suckers abundantly from the roots, often producing athicket within a few years.[11] A few other species are also found, somewhat rarely, in cultivation.[8]
Clerodendrum species are used as food plants by the larvae of some Lepidoptera species including Endoclita malabaricus and Endoclita sericeus. Both butterflies and hummingbirds are often attracted to blooming clerodendrum.
